Noelle has 5/6 of a yard of purple ribbon and 9/10 of a yard of Pink ribbon. How mucho ribbon does se have altogether?

Answers

Answer 1

Well you need to find a common denominator which 30 is the closest one. 5/6 becomes 25/30, 9/10 becomes 27/30. 27/30+ 25/30 = 52/30. To simplify that you divide by 2 to get 26/15. It is no longer divisible to a whole number after that point.

solve the equation 17=-13-8x with steps

Answers

17 = -13 - 8x .....add 13 to both sides
13 + 17 = -8x

The solution for given equation 17=-13-8x is x = -15/4.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given equation is,

17 = -13 - 8x

Now to solve the equation following steps are followed :

adding 13 both the sides of the equation,

17 + 13 = -13 - 8x + 13

or, 17 + 13 = -13 + 13 - 8x

Solving them we get,

30 = - 8x

or, - 8x = 30

multiplying -1 both side

- 8x*(-1) = 30*(-1)

Solving them we get,

8x = -30

dividing both side by 2

8x/2 = -30/2

Solving them we get,

4x = -15

dividing both side by 4

4x/4 = -15/4

Solving them we get

x = -15/4

Hence,the solution for given equation 17=-13-8x is x = -15/4.

Answers

First you have to distribute the 2x+11.
So multiply -4x2x and -4x11.
5x-8x-44=13
Add all your like terms so 5x+-8x.
-3x-44=13. Now add 44 to both sides.
-3x= 57. Now divide both sides by -3 to get the x by itself.
x=-19

5x-4(2x+11)=13

1)distribute the -4 to the numbers within the parenthesis.

5x-8x-44=13

2) next step you combine light terms.
''5x-8x=-3x''
so now you have -3x-44=13
3) add 44 on both sides
and you're left with -3x=57
4) divide both sides by -3 in order to solve for x; x divided by any number is always x, and 57divided by -3 is -19
5) so you're left with [n=-19] as your final answer

After that, we can divide both sides by -18, resulting in y=5/18. Next, plugging that into 4x-2y=9, we have 4x-10/18=9. Adding 10/18 to both sides, we get 4x=9+10/18.

the product of three consecutive nonzero integers

Answers

Final answer:

To find the product of three consecutive nonzero integers, multiply the first number by the next two numbers in the sequence.

Explanation:

If the first integer is n, the next will be n+1 and the next to it will be n+2

The product of three consecutive nonzero integers can be calculated using the formula:

n * (n+1) * (n+2)= n(n^2 + 3n+ 2)=n^3 +3n^2 + 2n

where 'n' represents the first integer. For example, if we take 'n' as 2, the three consecutive nonzero integers would be 2, 3, and 4. So, the product would be 2 * 3 * 4 = 24= (2)^3+ 3*(2)^2+ 2*2

Two of the angles in a parallelogram measure 5x° and 7x°. what is the value of x?

What is parallelogram?"It is a quadrilateral with opposite sides parallel.""The opposite angles of parallelogram are equal. "

For given question,

Two of the angles in a parallelogram measure 5x° and 7x°

The measure of an angle opposite to 5x° is also 5x°

Similarly the measure of an angle opposite to 7x° is also 7x°

So, we have the four angles of parallelogram as 5x°, 7x°, 5x°, 7x°

We know, the sum of all angles of quadrilateral is 360°

⇒ 5x° + 7x° + 5x° + 7x° = 360°

⇒ (5 + 7 + 5 + 7) x = 360

⇒ 24x = 360

⇒ x = 15

Therefore, the value of x is 15.

Your baseball team has a goal to collect at least 160 blankets for a shelter. Team members brought 42 blankets on monday and 65 on wednesday . Write and solve an inequality to find out how many blankets the team has to collect on friday?

Answers

y=160-(65+42). so it's 53

Answer:

Atleast 53

Step-by-step explanation:

We are given that your basketball team has a goal to collect atleast 160 blanket for a shelter.

Team member bought blankets on Monday =42

Team member bought blankets on Wednesday=65

We have to write an inequality and find the number of blankets has to collect on Friday.

Let x be the number of blankets bought by team members on Friday

According to question

[tex]42+65+x \geq 160[/tex]

[tex]107+x \geq 160[/tex]

Subtract 107 on both sides

[tex]107-107+x\geq 160-107[/tex]

[tex]x\geq 53[/tex]

Hence, team members bought atleast 53 blankets on Friday .

what is 50/12 in a mixed number

Answers

just divide 50 by 12

4 1/6

A fraction is when there is less than 1 whole i.e. 1/2
A mixed fraction is when there is more than 1 whole i.e. 1 3/4
A improper fraction is when there is more than 1 whole i.e. 50/12

As you may have observed, the thing which differentiates a mixed fraction from an improper fraction is that a mixed fraction's numerator is never bigger than it's denominator.
:)
50/12 is an improper fraction,
To convert this into a mixed fraction, we can find out how many times 50 fits in 12: 50/12 = 4.16666
So we know there are 4 wholes, which as twelfths are 48/12;
We can then observe the difference between 50 and 48 is 2 twelfths

So 50/12 as a mixed number/fraction is 4 wholes and 2 twelfths
which can also be written as 4 2/12 and then simplified to 4 1/6

What is the equation of a line passing through the points 6,3 and -4,3 so y=?

Answers

Answer:

y=3

Step-by-step explanation:

The required line will be y = 3 which is passing through points (6,3) and (-4,3)

What is the slope of the line?

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

To determine the line of passing through points (6,3) and (-4,3)

We have been given two points :(6,3) and (-4,3)

Let the required line will be:

(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )

Here

x₁ = 6, y₁ = 3

x₂ = -4, y₂ = 3

(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )

Substitute values in the above formula

(y - 3) = [(3 - 3)/(-4 -6 )](x -6 )

(y - 3) = [(0)/(-10 )](x -6 )

(y - 3) = 0

y = 3

Therefore, the required line will be y = 3

Although there are negatives and decimals, treat it as a normal multiplication problem while doing the math.

This will give you -13.3179, just move the decimal point down, and since a positive is being multiplied by a negative, the answer is negative. Once you have this number, just add it to -0.98. This is the same as subtracting, since it is negative, so in other words, just subtract 0.98 from -13.3179, and you have your answer.

This would be -14.2979, or roughly -14.2.
