Question

1. what value of r satisfies the equation $\frac{4r - 2}{5}=0.4$? enter the correct answer into the box. r =

Explanation:

Step1: Multiply both sides by 5

$5\times\frac{4r - 2}{5}=0.4\times5$
$4r - 2 = 2$

Step2: Add 2 to both sides

$4r-2 + 2=2 + 2$
$4r=4$

Step3: Divide both sides by 4

$\frac{4r}{4}=\frac{4}{4}$
$r = 1$

Answer:

$1$
