Solve for each of the following proportions:
a. 5/x=30/42
b. x/8=-12/32

A. x = 7

B. x = -3

Step-by-step explanation:

A.  5/x = 30/42

5/x = 5/7

5 = 5/7 x

5= 5x/7

5 x 7 = 5x

35 = 5x

35/5 = x

7 = x

x = 7

B.  x/8 = -12/32

x/8 = -3/8

x = - 3/8 x 8

x = -  24/8

x = -3

Hope this helps you have a gr8 day :3

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
