Question

5. Find the value of x in each of the following proportions.

a. 6:9 = x:72
b. 8/3 = 40/x
C. X:55 = 3:5
d. 33/x = 11/5

Answer 1

the value of x

`a.(6)/(9) = (x)/(72) \\ 432 = 9x \\ x = 48 \\ b. (8)/(3) = (40)/(x) \\ 8x = 120 \\ x = 15 \\ c. (x)/(55) = (3)/(5) \\ 5x = 165 \\ x = 33 \\ d. (33)/(x) = (11)/(5) \\ 11x = 165 \\ x = 15`
