The expression simplifies to 8.

$13 - 0.75 w + 8 x$ $13-0.75w+8x$ , where $w = 12 and x = \frac{1}{2}$ $w=12 and x=1/2$ .

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

$13 - 0.75 (12) + 8 (\frac{1}{2}) =$ $13-color(red)(0.75(12)) +color(blue)(8(1/2))=$

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

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

$8$ $8$
