Question

(vi) -5r = 0.5 tell the answer
​

Answer 1

Answer:

-5r=0.5 then r=5+0.5=5.5

Answer 2

Answer:

$\large\boxed{R=-0.1}$

Step-by-step explanation:

Isolate by the r on one side of the equation. Division property of equality is dividing from both sides of an equation by the same non-zero number and doesn't change the equation.

Given:

-5r=0.5

Solutions:

First, divide by -5 from both sides.

$\displaystyle\frac{-5r}{-5}=\frac{0.5}{-5}$

Solve.

Divide numbers from left to right.

$\displaystyle 0.5\div-5=\boxed{-0.1}$

$\large\boxed{R=-0.1}$

So, the correct answer is r=-0.1
