1.5x7 = 10.5 cups per week
I don't know how to convert it. probably a decimal or fraction.
here's how to convert, 10.5/16 = # gallon(s)
A translation
(I'm assuming that this isn't multiple choice since you didn't include the answer choices.)
We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.
10x- 9(x-2)=24
Distribute.
10x- 9x+18= 24
x+18= 24
Subtract 18 on both sides.
x= 6
Now, plug in x.
y= (6)-2
y= 4
We can check this to see if this works:
4= 6-2, 4=4
10(6)- 9(4)= 24
60-36= 24, 24=24
x=6 and y=4
I hope this helps!
