1 gallon = 2.93
2 gallons = 5.86
3 gallons = 8.86
Therefore the correct table is D.
Answer:
y = 3x+9
y = -4x +6
Step-by-step explanation:
Form an equation to describe the situation
x+y=10
Then use the other information they gave you and form another equation
x-y=2
You can add the two equations together, and you see that the y variables cancel out(elimination)
2x=12
Solve for one variable and then plug it back into the original equation
x=6
6+y=10
y=4
