Chapter 7: Q11. (page 246)

Apply the means-extremes property to $\frac{x}{10} = \frac{4}{5}$ and you get $5 x = ?$ and $x = ?$

Short Answer

Expert verified

The final answer is,

$5 x = 40$ and $x = 8$ .

Step by step solution

01

Step 1. Given information.

The given proportion is,

$\frac{x}{10} = \frac{4}{5}$

02

Step 2. Use mean extremes property.

Product of means is equal to product of extremes,

So,

$5 x = 40$

03

Step 3. Now, dividing through-out by .

$\begin{matrix} x = \frac{40}{5} \\ = 8 \end{matrix}$

Therefore, the final answer is $5 x = 40$ , and $x = 8$ .
