Which value if x makes this proportional true? 14/20=56/x A. x=62 B. x=70 C. x=80 D. x=100

Work Shown:

Let's cross multiply to get the following

14/20 = 56/x

14*x = 20*56

14x = 1120

x = 1120/14

x = 80

As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.

idk what the heck he answer is, i’m just putting this here so i finish my account
