Billy graphed the system of linear equations to find an approximate solution. y =-7/4 x +5/2 y =3/4 x – 3

Answer:

The answer is 5/36

Step-by-step explanation:

first, you are going to convert both of the fractions to have the same dinominator by multiplying by any of their factors.

32/36 - 27/36 = 536

Then you subtract the numerators and that's it

hope I helped :)

first you would put the expression in a fraction for

180/460

you already know that the both numbers are divisible by 2

the rule to prove that the number is divisible by three is when you add the digits of the number for example 333. 3+3+3=9 and nine is divisible by nine

THE ANSWER IS:::::::: 90/230

Answer:

B= 44.9506°

Step-by-step explanation:

WE apply sine angle formula

[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]

Given angle C = 51, c= 11 and b = 10

[tex]\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]

Plug in the values

[tex]\frac{10}{sin(B)}=\frac{11}{sin(51)}[/tex]

Cross multiply it

10 * sin(51) = 11* sin(B)

7.771459615 = 11 sin(B)

Now divide by 11 on both sides

0.706496328 = sin(B)

Now [tex]B = sin^{-1} (0.706496328)[/tex]

B= 44.9506°

Answer:

Step-by-step explanation: My answer would be 36.To figure this out,list all the multiples of 6,9,and 12.Once you do that you have to see which numbers occur in all three.Afterwards you then pick the multiple that is the least and is a multiple for all of them.

Hope this help!!!!!!!!

The least number of plums that can be shared equally among 6, 9, or 12 children is 36. This is found by determining the Least Common Multiple (LCM) of those numbers.

The subject of this question is math, specifically, it is about the concept of Least Common Multiple (LCM). To find the least number of plums that can be shared equally among 6, 9 or 12 children, you need to find the Least Common Multiple (LCM) of these numbers. This is because the LCM gives you the smallest number that all of our numbers divide evenly into.

Here's how you find the LCM of 6, 9, and 12:

Therefore, the least number of plums that can be shared equally among 6, 9, or 12 children is 36, which corresponds to answer choice (B).

Answer:

Option c is correct.

The sequence is, 2, -3 , -8 , -13, -18, .....

Step-by-step explanation:

Given the following as;

f(1) = 2

The recursive function is;[tex]f(n) = f(n-1) -5[/tex]             ......[1]

to find the sequence defined by the recursive function;

Put n=2 in [1];

[tex]f(2) = f(2-1) -5[/tex]

[tex]f(2) = f(1) -5[/tex]

Substitute the value of f(1) = 2 we have;

[tex]f(2) = 2-5 = -3[/tex]

Similarly, put n =3

[tex]f(3) = f(3-1) -5[/tex]

[tex]f(3) = f(2) -5[/tex]

Substitute the value of f(2) = -3 we have;

[tex]f(3) = -3-5 = -8[/tex]

for n = 4 we have;

[tex]f(4) = f(4-1) -5[/tex]

[tex]f(4) = f(3) -5[/tex]

Substitute the value of f(3) = -8 we have;

[tex]f(4) = -8-5 = -13[/tex] and so on .......

Therefore, we get the sequence defined by the recursive formula is,

2, -3 , -8 , -13, -18, .........

Answer:

36%

Step-by-step explanation:

9/25

multiply each by 4 to get 36/100

as a percent it would be 36%

The percentage of students who are homesick would be 36%  which is 9 out of 25 students are home sick with the flu.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 12×2 = 24

We have been given that 9 out of 25 students are home sick with the flu.

We have to determine the percentage of students who are homesick

⇒ (9/25) × 100

Apply the division operation, and we get

⇒ 0.36 × 100

Apply the multiplication operation, and we get

⇒ 36%

Therefore, the percentage of students who are homesick would be 36%.

Answer:

c) 2.082

Step-by-step explanation:

First you would add 1.567 and 2.345 together to get 3.912. If you take 3.912 and subtract 1.83 from that, it would be 2.082.

Hey there!

1.567 + 2.345 - 1.83 (5)

1.567 + 2.345 = 3.912

3.912 - 1.83(5)

1.83(5) = 9.15

3.912 - 9.15 = -5.238

Step-by-step explanation:

3/4 + 2/3

We must find the common denominator.

The list of multiples of 3: 0, 3, 6, 9, 12, 15, 18, ...

The common denominator is 12.

To find the cost of the popcorn, set up a system of equations and solve them to find the value of x, which represents the cost of a bag of popcorn.

To find the cost of the popcorn, we need to set up a system of equations. Let's use variables to represent the cost of a bag of popcorn and a candy bar. Let x be the cost of a bag of popcorn and y be the cost of a candy bar. We can set up two equations using the given information:

28x + 40y = 282

17x + 20y = 160.50

Now, we can solve this system of equations. Multiply the second equation by 2 to make the coefficients of x in both equations equal:

34x + 40y = 321

28x + 40y = 282

Subtract the second equation from the first equation:

34x - 28x + 40y - 40y = 321 - 282

6x = 39

Divide both sides of the equation by 6:

x = 6.50

Therefore, the cost of a bag of popcorn is $6.50.

Answer:

Maria made = $124.94

hope it helps

Step-by-step explanation:

if they made $187.41 and maria is getting twice a much as Andrew you'll divide 187.41 by 3 because maria is getting twice as more

187.41 ÷ 3 = 62.47

Andrew =  62.47

Maria = 62.47 x 2 = 124.94

to check your answer by adding 124.94 and 62.47 and should equal to the money made in total

124.94 + 62.47 = 187.41

Maria's profit from the lemonade stand business is calculated by dividing the total profit by 3 and then multiplying that amount by 2, as she is to receive twice as much as Andrew.

The question involves calculating Maria's share of the profit from their lemonade stand business. With a total profit of $187.41, and the agreement that Maria should receive twice as much as Andrew, we can set up an equation to solve the problem. Let's denote Maria's profit as M and Andrew's profit as A. The equation based on their agreement is M = 2A. Since the total profit is their profits added together, we have another equation: M + A = $187.41. Substituting the first equation into the second, we get: 2A + A = $187.41, which simplifies to 3A = $187.41. Dividing both sides by 3 to isolate A, A = $187.41 / 3. Calculating this gives us Andrew's profit, and multiplying A by 2 gives us Maria's profit.

Answer:

Correct options are 1 and 5.

Step-by-step explanation:

If parallel lines m and n are cut by a transeversal t, then corresponding angles are equal in measure. Therefore,

∠2≅∠6;

∠1≅∠5;

∠3≅∠7;

∠4≅∠8.

If parallel lines m and n are cut by a transeversal t, then interior angles on the same side are supplementary. Thus,

∠3+∠5=180°;

∠4+∠6=180°.

If one of the angles ( let it be angle 3) formed measures 58°, then m∠5=180°-58°=122°. Then

m∠2=m∠3=m∠6=m∠7=58°;

m∠1=m∠4=m∠5=m∠8=122°.

You can conclude that there are three more angles with the same measure of 58° and four of the angles measure 122°.

The polynomial 5x3 + 2x + 7x5 written in descending form is 7x5 + 5x3 + 2x, organized from the highest to the lowest power of x.

To write the polynomial 5x3 + 2x + 7x5 in descending form, arrange the terms in order from the highest power of x to the lowest. The given polynomial has the terms with powers of 5, 3, and 1. Organizing the polynomial in descending order of the exponents gives us:

7x5 + 5x3 + 2x.

As we can see, the term with the highest exponent, 7x5 (degree 5), comes first, followed by 5x3 (degree 3), and lastly the term with the lowest degree, 2x (degree 1).
