The density of a fish tank is 0.2 fish over feet cubed . There are 8 fish in the tank. What is the volume of the tank?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

probably .5

i can on others if necessary.

t= 1/3.

hope this .

step-by-step explanation:

the answer is 9 because the question is telling how much it be together.
