X = (7 + Y) (7 - Y)
2 + Y
F = 1/2(r + 6.5)
2f = r + 6.5
r = 2f - 6.5
(1/3) of (14-1/3) = (1/3) x (43/3) = (43/9) = about <em>(4 and 7/9) gallons</em>.
2 1/4 times 3 1/9
Make the fractions into decimals
So now it’s 2.25 times 3.11...
Multiply that to get 6.99 but since the 3.11... is a repeated sequence you would round it to 7, which is your answer!
