Given:
The expression is
[tex]8p+3q-18[/tex]
To find:
The value of the expression when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].
Solution:
We have,
[tex]8p+3q-18[/tex]
Putting [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex], we get
[tex]8(\dfrac{1}{2})+3(7)-18[/tex]
[tex]=4+21-18[/tex]
[tex]=7[/tex]
Therefore, the value of the expression is 7 when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].
