Respond quick solve the first proportion for x. use that value to solve the second proportion for y. , x/24 = 9/72, x/9 = y/12 a. x = 3, y = 4 b. x = 4, y = 3 c. x = 27, y = 36 d. x = 3, y = 6

A

Step-by-step explanation:

3/24=9/72        3*3=9    24*3=72      x=3

3/9=y/12         9/3=3        12/3=4      y=4

X=3 y=4

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
