Final answer:

To evaluate the expression 3m - 2 + 8k, substitute the given values for m and k and simplify the expression.


Step-by-step explanation:

To evaluate the expression 3m - 2 + 8k, we substitute the given values for m and k. Since m = 7 and k = -2, we replace m with 7 and k with -2 in the expression. This gives us:

3(7) - 2 + 8(-2)

Simplifying this expression, we get:

21 - 2 - 16

Which further simplifies to:

3

So, when m = 7 and k = -2, the value of the expression 3m - 2 + 8k is 3.
