Answer:
16
Step-by-step explanation:
To solve we must first find what the given ratios equal
8/5 = 1.6
40/25 = 1.6
48/30 = 1.6
this means that x/10 = 1.6
To find x... multiply both sides of this equation my 10 to get x alone
x=1.6×10
x=16
Answer:

We can write a proportion to solve
14 10
------ = ------
21 x
Using cross products
14x = 21*10
14x =210
Divide each side by 14
14x/14 = 210/14
x =15
