Respuesta :

Value of the expression will be 7

Explanation

Given value of the variables are : [tex]p= \frac{1}{2}[/tex] and [tex]q=7[/tex]

Given expression: [tex]8p+3q-18[/tex]

So, plugging the values of [tex]p[/tex] and [tex]q[/tex] into the above expression, we will get...

[tex]8p+3q-18\\ \\ = 8(\frac{1}{2})+3(7)-18\\ \\ =4 + 21-18\\ \\ =25-18\\ \\ =7[/tex]

So, the value of the expression will be 7.
