Answer:
12×0.25 is definitely right
×0.25 is another way of finding a quarter of something. I looked at the other answers and I think this one is the only correct one
Quotient means division, which is obvious by all the division answers.
It says "Quotient of 4 AND ..." which means that four will be on top and everything else will be on the bottom.
So now you have:

four over something unknown.
Reading the rest of the question, "the sum of a number and three"
Sum means addition, again obvious by the answer choices.
"a number" is an unknown, so we can set that to x
and this x is being added to by three, so therefore
x+3 would be in your denominator.
You final equation should look like this:;

OR answer choice

Answer:
y+5/3x=34/3
Step-by-step explanation:
y=mx+b
3=5m+b
-2=8m+b (system of equations, subtract them)
5=-3m
-5/3=m
3=5m+b
3=5(-5/3)+b
3=-25/3+b
9/3+25/3=b
34/3=b
y=-5/3x+34/3
y+5/3x=34/3
