What's the problem you need help with
You would divide 27/6.75.
You'd get 4, so 4 people went.
To check you would do 4x6.75 and your get the total of 27$
(fog)(x)=f(g(x))
f(g(x))=3(-4x+7)+5
f(g(-4))=3(-4(4)+7)+5=3(-16+7)+5=3(-9)+5=-27+5=-22
(fog)(-4)=-22
Answer:8x+4w
Step-by-step explanation:
So the question is
3x+4w+7x-2x
We take the variables that are the same which are
3x
7x
-2x
We add all of these together
3x+7x+(-2x)=8x
8x is our answer, so we take 8x and add 4w to it
8x+4w
This is the final answer, because there is nothing else left to do
