<u />
<u />
<u />
<u>Step 2: Find Unknown</u>
- Multiply both sides by 8/15:
![\frac{8}{15} \cdot \frac{r+s}{x-y} = \frac{8}{15} \cdot \frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D%20%5Ccdot%20%5Cfrac%7Br%2Bs%7D%7Bx-y%7D%20%3D%20%5Cfrac%7B8%7D%7B15%7D%20%5Ccdot%20%5Cfrac%7B3%7D%7B4%7D)
- Distribute/Multiply:
![\frac{8r+8s}{15x-15y}= \frac{24}{60}](https://tex.z-dn.net/?f=%5Cfrac%7B8r%2B8s%7D%7B15x-15y%7D%3D%20%5Cfrac%7B24%7D%7B60%7D)
- Simplify:
![\frac{8r+8s}{15x-15y} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8r%2B8s%7D%7B15x-15y%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)

Answer:
B
Step-by-step explanation:
A=1/2*(10+20)*5
=1/2*30*5
=75m*2
To find this number, let's represent the unknown amount of students with the variable x:
356 + 365 + x = 977
721 + x = 977
x = 256
There are 256 students in ninth grade.
