Answer:
7
Step-by-step explanation:
Hallo Ialejo123!
Remember when two numbers are right next to it it represents multiplication. I've replaced it so it makes more sense:
When p = [tex]\frac{1}{2}[/tex] and q = 7:
8 × [tex]\frac{1}{2}[/tex] + 3 × 7 - 18
We can put parenthesis around what we solve first (according to the Order of Operations):
(8 × [tex]\frac{1}{2}[/tex]) + (3 × 7) - 18
Simplify!
4 + 21 - 18
Again, simplify!
25 - 18
Which gives [tex]\boxed{7}$[/tex] as our answer.
