Question

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

Answer 1

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
