Question

5m + 9n If m =-7 and n = 4 Evaluate each expression given the variable replacement

Answer 1

To solve this expression, we can substitute -7 and 4 in for our variables. This would look like:

5(-7) + 9(4) = -35 + 36

= 1

Therefore, the evaluation process would result in 1 as our answer.

Answer 2

Step-by-step explanation

We are given an expression

`5m+9n`

We are told to evaluate the expression when m=-7 and n=4

To do so, we will simply substitute m=-7 and n=4 into the question, so we will have

`5(-7)+9(4)=-35+36=1`

Therefore, the answer is 1
