Sagot :

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

  • y = 12
  • x = 1/2

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
