8p + 3q - 18 when p = 1/2 and q = 7
You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.
Rewrite your expression to include the values of p and q plugged in. Your expression should look like:
8(1/2) + 3(7) - 18
According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:
4 + 21 - 18
According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.
4 + 21 = 25
25 - 18 = 7
Your answer is 7.
