We know this: 2/7 G = 3/5 B
We know this: B = (G - 165)
Plug the second equation into the first to solve for G: 2/7 G = 3/5(G - 165)
Solve from there.
G = 315
Plug that into the second equation: B = (G - 165)
B = 315 - 165
B = 150
G + B = 465

So first write down the fraction which is 8/28
then make it into its simplest form which is 2/7
then make it into ration form it is 2:7
reading 2 is to 7
Answer:
there is no graph
Step-by-step explanation:
The answer will be A because 3x=-3
X= -1
