Question

Expression when m=8 and n=7 n+6m

Answer 1

in the expression n+6m, subst. 8 for m and 7 for n:

7+6(8) = 55 (answer)

Answer 2

All you have to do is plug m and n into the equation:

n+6m

Since n=7, you'll get:

7+6m

And since m=8, you'll get:

7+6(8)

And by doing the order of operations (PEMDAS), you'll start off multiplying 6 and 8, which is 48, then add 7, which is 55.

Your answer should be 55!
