Question

Which of the following values of r will result in a true statement when substituted into the given equation? -r + 5(r + 2) = -10 A. r = -6 B. r = -5 C. r = 0 D. r = 1

Answer 1

Answer:

Choice B is correct.

Explanation:

The given equation is -r+5(r+2)=-10

Put r=-5 into the above equation

-(-5)+5(-5+2)=-10

5+5(-3)=-10

5-15=-10

-10=-10

Right and left side of above equation is equal by putting r=-5 so it is true statement.
