Question

How do you evaluate `13-0.75w+8x` when w=12 and x=1/2?

Answer 1

The expression simplifies to 8.

Explanation:

`13-0.75w+8x`, where `w=12 and x=1/2`.

Substitute the values for `w and x` into the expression.

`13-color(red)(0.75(12)) +color(blue)(8(1/2))=`

`13-color(red)(9)+color(blue)(4)=`

`color(red)4+color(blue)4=`

`8`
