Note: I am assuming you meant to write the value of y = 12 instead of w = 12.
So, I am assuming y = 12
Answer:
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
[tex]13\:-\:0.75y\:+\:8x[/tex]
Given
substituting y = 12 and x = 1/2 in the expresion
[tex]13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)[/tex]
[tex]=13-0.75\cdot \:12+8\cdot \frac{1}{2}[/tex]
[tex]=13-9+4[/tex]
[tex]=8[/tex]
Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8
