Given that 5 x : 8 = 7 : 2 Calculate the value of x .

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6
