Question

Evaluate the expression when m = 4.



35 – 3m



A.
1


B.
13


C.
23


D.
128

Answer 1

35 – 3(4)
3 * 4 = 12
35 - 12 = 23
m = 23

Answer 2

At first you got to know that when you say "3m" you mean "3 times m"
So, your expression is \(\large\color{black}{ 35-3\times m }\) .

And based on the order of operations, you multiply first.
So first multiply and then subtract.

Your question gives an additional information though, it says that m=4, so plug in 4 instead of m (replace "m" with 4).

\(\large\color{black}{ 35-3\times 4 }\)

Now just multiply

\(\large\color{black}{ 35-12 }\)

And lastly subtract.

\(\large\color{black}{ 23. }\)
