Question

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

Answer 1

Answer:

x = 12.6

Step-by-step explanation:

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

$\frac{a}{b} = \frac{c}{d}$

can be rewritten as:

a*d = c*b

For this case:

$\frac{5}{7} = \frac{9}{x}$

5*x = 7*9

x = 63/5

x = 12.6
