Solve 5(y - 4) = 7(2y + 1)

Answers

Answer 1
5y-20=14y+7

5y-20+20=14y+7+20

5y-14y=14y + 27 -14y

9y=27
Divide both by -9
Y=-3
Answer 2
5(y-4)=7(2y+1)   use the distributive property: 5y-20=14y+7   then isolate one variable: 5y-20(-7)=14y+7(-7)   which is: 5y-13=14y    next subtract 5y from 14y which gives you: -13=9y   the last step is to divide each side by 9, isolating y. your answer will be y=-1.4

an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle at the rate of 2 seats in 11 minutes. Write a proportion relating the number of seats s to the number of minutes m. At this rate, how long will it take to add 16 seats? 19 seats?

Answers

Rate = 2 seats/11 minutes = 2/11  seats/min

Therefore the time required for s seats is
[tex](m \, min) = \frac{s \, seats}{ \frac{2}{11} \, \frac{seats}{min} } = \frac{11s}{2} \, min[/tex]
That is,
m = (11s)/2 min

When s = 16, obtain
[tex]m = \frac{11(16)}{2} = 88 \, min[/tex]

When s = 19, obtain
[tex]m = \frac{11(19)}{2} = 104.5 \, min[/tex]

Answers:
[tex]m = \frac{11s}{2} [/tex]
When s = 16, m = 88 min

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x+2) ?



The graph of g(x) is the graph of ​f(x)​ translated 2 units left.

The graph of g(x) is the graph of ​f(x)​ translated 2 units up.

The graph of g(x) is the graph of ​f(x)​ translated 2 units down.

The graph of g(x) is the graph of ​f(x)​ translated 2 units right.

Answers

It would be the first answer, the graph if g(x) is the graph of f(x) translated 2 units left
This is because the +2 is in the parentheses with the x which makes it move left or right and because it’s positive you would do the opposite and more it left

we have that

[tex]f(x)\\g(x)=f(x+2)[/tex]

we know that

the rule of the translation of f(x) to g(x) is equal to

[tex](x,y)----> (x-2,y)[/tex]

that means

the graph of g(x) is the graph of f(x) translated [tex]2[/tex] units left

therefore

the answer is the option

the graph of g(x) is the graph of f(x) translated [tex]2[/tex] units left

A)The root at point P may be 3/5.
B)The root at point P may be 1/5.
C)The root at point P may be 5/3.
D)The root at point P may be 1/3.

Answers

The roots of f(x) are the values for x at which f(x)=zero. The root of f(x) at point P is a bit redundant, since point P is the root of the function (and based on the graph, the only root). 

We could plug zero in for f(x) to find the value of x at Point P, but based on the graph/options provided and the complexity of the function, it may be easier to just eyeball the graph to get the correct answer. We see that point P is between 1/2 and 1 on the x-axis. 

Of the options provided, we want the value for x that satisfies: 1/2 < x < 1

Write an expression with four terms. Include at least one term with an exponent, one term with a coefficient of 5, one term with three factors, and one constant. Make two of the terms like terms.

Answers

An algebraic expression is looking something like this: 8x³ + 5
This expression has two terms; 8x³ and 5
The value of '8' in 8x³ is called COEFFICIENT
The value of '3' in 8x³ is called POWER or INDICES
The term 8x³ is called  an exponent because it has power/indices
The letter 'x' in the term 8x³ is called VARIABLE

So, we want an expression with four terms
_____ ⁺/₋ _____ ⁺/₋ _____ ⁺/₋ _____

One term with an exponent ⇒ You can choose any letter and any power that will go with it, for example, 6x⁴

One term with a coefficient of 5 ⇒ 5x⁴

One term with three factors ⇒ This could be a combination of any three letters that represent three values for example 'abc'. This term means a × b × c, so it has three factors.

One constant ⇒ Choose any number, say 45

Make two of the terms like terms ⇒ We have 6x⁴ + 5x⁴; these two terms are alike, they are in term of x⁴

Putting the four terms together: 6x⁴ + 5x⁴ + abc + 45

An expression satisfying all the conditions specified is [tex]5x^2 + 5xy + 3xy + 7[/tex]

Here's an expression with four terms that meets all the requirements :

[tex]5x^2 + 5xy + 3xy + 7[/tex]
1. Term with an exponent: [tex]\( 5x^2 \)[/tex] (The exponent is 2)
2. Term with a coefficient of 5: [tex]\( 5xy \)[/tex]
3. Term with three factors: [tex]5xy[/tex] (The factors are 5, x, and y)
4. Constant term: 7
Like terms:[tex]\( 5xy \)\ and\ \( 3xy \)[/tex]
So the expression [tex]\( 5x^2 + 5xy + 3xy + 7 \)[/tex] includes all the specified requirements.

Kayla has $500 in her account, and she spends $40 a week on food. If she falls below $30 in her account, she must pay a penalty. What is an inequality that can represent this situation?

Answers

She starts with $500; that's a given. If she's spending $40 a week, that means that she'll be subtracting $40 from her account for each week (let's call the number of weeks that've gone by "w"), leaving her with 500-40w dollars after week w.

Now we have to compare this somehow to $30. Our inequality is going to look like:

500-40w ? 30

Where the ? is a stand-in for an inequality sign. Which inequality sign should we pick? Take a look at the question and see if you can find any keywords that might give you a hint. "If she falls below" is the big one I'm seeing. If she can't fall below $30, that means she'll always have to stay at or above $30 to avoid paying the penalty. What inequality sign represents at or above?

Final answer:

The inequality that represents this situation is: 500 - 40w < 30, where w represents the number of weeks that have passed.

Explanation:

The situation can be represented by the inequality:

500 - 40w < 30

where w represents the number of weeks that have passed.

This inequality states that the amount of money remaining in Kayla's account (500 - 40w) must be less than $30 for her to have to pay a penalty. If Kayla's account falls below $30, she would have to pay a penalty because she does not have enough money to cover her regular expenses.

For example, if we substitute w = 10 into the inequality, we get 500 - (40 × 10) < 30, which simplifies to 100 < 30. Since 100 is not less than 30, Kayla would not have to pay a penalty.

One leg of a right isosceles triangle is 8 feet. What is the area of the triangle?

Answers

Step-by-step explanation:

a little late on this answer

The area of a right isosceles triangle with legs each measuring 8 feet is calculated using the formula A = (base x height) / 2, resulting in an area of 32 square feet.

The question you've asked is about finding the area of a right isosceles triangle when one leg is known. In a right isosceles triangle, both legs are of equal length. Since one leg is given as 8 feet, the other leg is also 8 feet. The formula for the area of a right triangle is A = (base x height) / 2.

In this case, the base and height are the same, which are the lengths of the legs of the triangle, so the formula becomes A = (8 feet x 8 feet) / 2. Performing the calculation, we find that A = 64 feet2 / 2, which simplifies to A = 32 feet2. Therefore, the area of the triangle is 32 square feet.

Find the difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712

Answers

Final answer:

The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.

Explanation:

The difference between the product and the sum can be found by first calculating the product of 26.22 and 3.09 and then calculating the sum of 3.507, 2.08, 11.5, and 16.712. Once both of these values are calculated, subtract the sum from the product to find the difference.

To calculate the product of 26.22 and 3.09, you would multiply these two numbers:

26.22 × 3.09 = 81.0198

To calculate the sum of 3.507, 2.08, 11.5, and 16.712, you would add these numbers together:

3.507 + 2.08 + 11.5 + 16.712 = 33.799

Finally, to find the difference, subtract the sum from the product:

81.0198 - 33.799 = 47.2208

The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.

Explanation:

We are given 10 degrees Celsius, so C = 10. We will plug this into the given equation. In other words, replace the C with 10. Then use PEMDAS to simplify the right side of the equation

F = (C * 1.8) + 32
F = (10 * 1.8) + 32
F = 18 + 32
F = 50

how to solve 5 hours to 720 minutes

Answers

Final answer:

To convert hours to minutes, multiply the number of hours by 60. When adding or subtracting time, work with like units first and simplify when needed. For conversion, it's also helpful to understand that 60 minutes equals 1 hour for fractional time units.

Explanation:

Converting units of time such as hours to minutes involves understanding the relationship between these units. In this case, the conversion factor between hours and minutes is that 1 hour is equivalent to 60 minutes.

Therefore, to convert hours into minutes, you would multiply the number of hours by 60.

Here's an example on how to convert 5 hours to minutes:
5 hours = 5 × 60 minutes = 300 minutes.

In this context, let's look at a smaller unit to larger unit conversion example:
120 seconds = 120 ÷ 60 = 2 minutes. Dividing the number of seconds by 60 converts seconds to minutes.

Now, let's consider another example by converting a larger unit to a smaller unit:
4 hours = 4 × 60 minutes = 240 minutes. Multiplying the number of hours by 60 converts hours to minutes.

Adding measures of time involves combining like units first, as in the example of adding 1 hour 55 minutes to 45 minutes, resulting in 1 hour 100 minutes. This can be simplified by recognizing that 60 minutes is equivalent to 1 hour, resulting in a total of 2 hours.

Subtraction of time units might require 'borrowing' from a larger unit, such as borrowing 60 minutes from an hour, to facilitate the subtraction process.

Hence, for 5 hours 10 minutes minus 30 minutes, we adjust it to 4 hours 70 minutes and then subtract, resulting in 4 hours 40 minutes.

How to identify the place value of a digit in a number?

The place values on the left of the decimal point start as ones, tens, hundreds, and so on. The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so on. The tens mean multiplied by 10. The tenth means the tenth part of that digit which is that digit divided by 10

We are given multiple number names and asked to add them.

We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.

We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.

To find this problem, it will be easier to split the sentences into multiple parts like this;

1. "2 tens" mean 2 x 10 =20

2. "15 ones" mean 15 x 1= 15

Then, if we add them up it will be;

20+15= 35

The answer to this problem would be 35

Therefore, the number that will be equal to 2 tens 15 ones is 35.

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation.

let the consecutive integers are x  and x+1.

So,

x+ (X+ 1)= -15

2x + 1 =-15

2x= -16

x= -8

80 girls and boys have planned for a movie. They are in a ratio of 6 girls to 2 boys . How many girls are there?

Answers

Let g represent the amount of girls at the movie and b represent the amount of boys, and t represent the total amount of kids at the movie. t = g + b the equation the represents the situation, so 8 = 6 + 2 represents that if there is a total of 8 kids, there are 6 girls and 2 boys. Because the ratio is 6:2, the amount of girls to the total amount of kids is 6:8 (which is the same is 3/4) and the amount of boys to the total amount of kids is 2:8 (which is the same is 1/4). Therefore, the equation that represents the situation is t = 3/4t + 1/4t, meaning that g = 3/4t and b = 1/4t. If there is a total of 80 kids, replace t with 80 and solve for g (number of girls at the movie): 

g = 3/4t

g = 3/4(80)

g = 60

There are 60 girls at the movie.
