Which value if x makes this proportional true? 14/20=56/x A.x=62 B.x=70 C.x=80 D.x=100​
Leya [2.2K]
<h3>Answer:  C) x = 80</h3>

==================================================

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.
