Answer:
7
Explanation:
If m = 3, the first step you would take is to replace m in the expression 9/m + 4 with the number 3 so the expression reads 9/3 + 4.
In PEMDAS, division comes before addition so you will take take care of 9/3 first. 9/3 = 3.
Replace 9/3 with 3 in the expression so that it says 3 + 4. Then, solve the addition or 3 + 4.
Does that help?
