Note: I am assuming you meant to write the value of y = 12 instead of w = 12.

So, I am assuming y = 12

The value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

Step-by-step explanation:

Given the expression

$13\:-\:0.75y\:+\:8x$

Given

y = 12x = 1/2

substituting y = 12 and x = 1/2 in the expresion

$13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)$

$=13-0.75\cdot \:12+8\cdot \frac{1}{2}$

=13-9+4

Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

32x - 8

Step-by-step explanation:

A = LW

A = (8x - 2)(4)

A = 32x - 8
