The anwer is b because you can multiply or subraction from it
We want to find y from the equation
![\frac{3}{y-2} =8](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7By-2%7D%20%3D8)
Multiply each side by (y - 2).
![(y-2).( \frac{3}{y-2)}) = 8(y-2)](https://tex.z-dn.net/?f=%28y-2%29.%28%20%5Cfrac%7B3%7D%7By-2%29%7D%29%20%3D%208%28y-2%29%20)
Note that (y-2) in the numerator and denominator cancel out on the left side.
Therefore
3 = 8(y - 2)
3 = 8y - 16
Add 16 to each side.
3 + 16 = 8y - 16 + 16
19 = 8y
Divideach side by 8.
19/8 = y
Answer:
Answer:
50%
Step-by-step explanation:
Total students = 12 + 18 + 6 = 36
Seventh-graders = 18
18/36*100 = 50%
245,195,145,95,45
explanation: 245-195 is 50 so you subtract 50 from 195 and get 145 and subtract 50 from that and get 95
