Yes they can. They have to be more clear and collected
There were 60 girls because you do cross multiplication (5 x 48 is 240 4 x 60 is 240)
Y=-3
-3=-1.5x
you substitiue y value, then you divide both sides by -1.5 and you get 2 for x.
(2,-3)
y=4.5
4.5=-1.5x
you substitute y value, then again you divide both sides by -1.5 and you get 3.
(3,4.5)
y=6
6=-1.5x
same thing for this last one. then once again divide by -1.5 and you get -4.
(-4,6)
The answer is B, 7.We can factor a 2 out of this:
We can't factor anything.
We can factor a 4 out of this:
We can factor an 8 out of this:
So your answer is B, 7.
