Answer:
Step-by-step explanation:
For this case the density is given by:
D = fish / volume
By clearing the volume we have:
volume = fish / D
Substituting values:
volume = (8) / (0.2)
volume = 40 feet ^ 3
Answer:
the volume of the tank is:
40 ft3
Answer:
9/16
Step-by-step explanation:
i got it right on khan academy
3x + 3 = 3y < -- make this 3x - 3y = -3
2x - 6y = 2
multiply by 2 on the first equation
6x - 6y = -6
2x - 6y = 2
subtract them
4x = -8
x = -2
substitute x = -2 into any of the equation
2x - 6y = 2
2(-2) - 6y = 2
-4 - 6y = 2
-6y = 6
y = -1
So the answer is
(-2 , -1)
