Question

Evaluate each expression for the given value (please answer all)

-20a - 65 for a=2.7

-6 + 52 for x=1 1/6

Answer 1

-20a - 65 = -104 for a = 2.7

-6x + 52 = 45 for x = 1 1/6

Explanation:

-20a - 50 for a = 2.7

Insert 2.7 in for a.

-20(2.7) - 50 = -54 - 50 = -104

-6x + 52 for x = 1 1/6

Insert 1 1/6 for x.

-6(1 1/6) + 52 = -7 + 52 = 45
