Question

Use the Means-Extremes Property to solve for x. 57 =9x x =

Answer 1

x = 12.6

Explanation:

When you have one fraction equated to another one, the means-extremes property allows you to cross multiply, as follows:

`(a)/(b) = (c)/(d)`

can be rewritten as:

a*d = c*b

For this case:

`(5)/(7) = (9)/(x)`

5*x = 7*9

x = 63/5

x = 12.6
