Y= 9.2

Explanation:
13(y+7)=3(y-1)

Distribute the 13 on the left side and the 3 on the right side.

13y+91=3y-1

Subtract the 3y to the 13y (little brother goes to the big brother always)

10y+91=-1

Subtract 91 to the right side.

10y=92

Divide by 10.

Can somebody pls show me how to solve this?

Answer:

C. 52.5

Step-by-step explanation:

The total from W(-20) to Z(120) is 140.

You can add up all of the numbers in the ratio, 2:3:3, to get 8

Divide 140 by 8 to get 17.5

Multiply 17.5 times the number in the ratio for each segment, so the new ratio would be 35 : 52.5 : 52.5

Since you are trying to find segment XY, which was the 2nd number in the ratio, you would get your answer as 52.5
