Question

Evaluate -8w + 3z when w = 2.2 and z = -9.1.

Answer 1

-8w+3z
w=2.2
z=-9.1

-8(2.2)+3(-9.1)
-17.6-27.3
-44.9

The answer is -44.9

Answer 2

-8w + 3z when w = 2.2, z = -9.1

Simply plug in everything.

Plug in 2.2 for w, and -9.1 for z :)

-8(2.2) + 3(-9.1)

Simplify.

-17.6 + (-27.3)

-17.6 - 27.3

Simplify.

-44.9
