Hi, I am struggling on this math question. Can someone help me out please? I more so need how to set up the equation than the answer. The aquarium has 6 fewer yellow fish than green fish. 40 percent of the fish are yellow. How many green fish are in the aquarium?

Y = number of yellow fish

G = number of green fish

Y = G - 6

Y = 0.40 * (Y+G)

G - 6 = 0.4*(G-6+G)

G - 6 = 0.4*(2G-6)

G - 6 = 0.8G -2.4

0.2G = 3.6

G = 3.6/0.2=18

There are 18 green fish.

Step-by-step explanation:

18 green fish and there are 12 yellow fish

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
