Question

Which expression has a solution of 27, if r = 3? 8 r 6 r 9 r 7 r

Answer 1

Answer:

8r.

Step-by-step explanation:

If we substitute 3 into all of these equations, we get

8(3) which equals 24

6(3) which equals 18

9(3) which equals 27

7(3) which equals 21

8r is the one that equals 24 when 3 is substituted.
