Answer:

b=\frac{c-3a}{2}

Step-by-step explanation:

To solve for b, we need to isolate b from the other variables. We can do this by subtracting '3a' by both sides. We get:

2b= c-3a

Now, to get 'b', we will need to divide both sides by 2. This results in:

b=\frac{c-3a}{2}

This is your answer!

Schach [20]

Answer:

the teacher bought 100 balloons, and 95 of them were left for the party.

Step-by-step explanation:

red balloons is given, 40.

first you find the green balloons.

<em>the number of green balloons is 3/5 the number of red balloons.</em>

3/5 * 40 = 24

so there are 24 green balloons.

next is yellow balloons.

<em>the number of green balloons is 2/3 the number of yellow balloons.</em>

24 = 2/3 * x

24 ÷ 2/3 = x

24 ÷ 2/3 = 36

there are 36 yellow balloons.

find the total balloons:

40 + 24 + 36 = 100

the teacher bought 100 balloons.

1/20 of the red balloons popped.

1/20 * 40 = 2

2 of the red balloons popped

1/12 of the green balloons popped

1/12 * 24 = 2

2 of the green balloons popped.

1/36 of the yellow balloons popped

1/36 * 36 = 1

1 yellow balloon popped

2 + 2 + 1 = 5

100 - 5 = 95

there were 95 balloons left for the party.

e-lub [12.9K]

SOLUTION

Given the question in the question tab, the following are the solution steps to get the rental cost for each movie and each video game.

Step 1: Write the representation for the two rentals

Let m represents movies

Let v represent video games

Step 2: Write the statements in form of a mathematical equation

\begin{gathered} \text{Month 1: }4m+8v=57 \\ \text{Month 2: }2m+3v=23 \end{gathered}

Step 3: Solve the equations above simultaneously using elimination method to get the values of m and v

\begin{gathered} 4m+8v=57----(1) \\ 2m+3v=23----(2) \\ \text{ multiply equation 1 by 2 and equation 2 by }4 \\ 8m+16v=114----(3) \\ 8m+12v=92----(4) \\ \text{subtract equation (4) from equation (3)} \\ 4v=22 \\ v=\frac{22}{4}=5.5 \\ \text{Substitute 5.5 for v in equation 1 to get the value of m} \\ 4m+8v=57 \\ 4m+8(5.5)=57 \\ 4m+44=57 \\ 4m=57-44=13 \\ m=\frac{13}{4}=3.25 \\ m=\text{\$}3.25,v=\text{\$}5.50 \end{gathered}

Rental cost for each movies is $3.25

Rental cost for each video games $5.50
