Answer: Choice B) 15
=======================================================
Explanation:
The variables m and n are placeholders for numbers. In this case, we replace m with 3 and n with 2 since m = 3 and n = 2.
We'll use PEMDAS to simplify
So,
7m - 3n
7*3 - 3*2
21 - 6
15
The expression 7m-3n turns into 15 after plugging in those m and n values, and simplifying.
Answer:
21-6=15. 15 is your answer. (B)
Step-by-step explanation:
…
It’s a simple problem
If the value of m=3,
Then 7*3=21
And if n’s value is 2, then 3n would be 3*2, which is 6.
And if we put it in equations:
21-6,
THEREFORE, we get 15, also known as 15.
