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
Step-by-step explanation:
