Question

Which letter on the number line represents the solution to -2.5r = -20? A) Point P B) Point Q Eliminate C) Point R D) Point S

Answer 1

Point R = 8

Explanation:

-2.5 r = -20

The solution to this equation is represented by a number line

In the given equation we have only the variable 'r'

We will get the value of 'r' while solving the above equation

That 'r' value is the solution point R on number line

`-2.5r = -20`

divide by -2.5 on both sides

`r=(-20)/(-2.5)`

r= 8 is our solution
