D. 3 - 5m

Answer 1

one way to do this, is first use numbers.
For example, what is 5 less than 8 ?

Answer 2

remember, if there is "less than, it implies that it is being subtracted

So ___ - 5.

Then, 3 times the number m can be thought of as multiplication. As we explored in the last problem, they go next to each other.

B

Answer 4

@phi 's method is also good. Kind of gives you a perspective to where things go, since the wording of these problems are what get people off track.

saying "what is 8 less than 5?" is backwards, in a sense.

and B is correct, nice work
