Answer 1

7

Explanation:

Answer 2

Value of the expression will be 7

Explanation

Given value of the variables are :
`p= (1)/(2)` and
`q=7`

Given expression:
`8p+3q-18`

So, plugging the values of
`p` and
`q` into the above expression, we will get...

`8p+3q-18\\ \\ = 8((1)/(2))+3(7)-18\\ \\ =4 + 21-18\\ \\ =25-18\\ \\ =7`

So, the value of the expression will be 7.
