Question

PLEASE IF YOUR A MATH EXPERT ANSWER THIS I'M LOSING MY SANITY

What is the value of 7m−3n when m = 3 and n = 2?
A: 5
B: 15
C: 24
D: 36

Answer 1

Answer: Choice B) 15

=======================================================

Step-by-step 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 2

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.
