Question

Write an
expression that is equivalent to -0.5(20f – 16).

Answer 1

Apply distributive law

• a(b-c)=ab-ac

`\\ \tt\longmapsto -0.5(20f-16)`

`\\ \tt\longmapsto -0.5(20f)-0.5(-16)`

`\\ \tt\longmapsto -10f+8`

Answer 2

• - 10f + 8

Explanation:

Given expression:

• - 0.5(20f - 16)

Distribute and simplify:

• -0.5(20f) - 0.5(- 16) =
• - 10f + 8
