Nahhhh
So basically WHERE DID THE x COME FROM anyway ???
5 * 7 = 35
but
IT DOES NOT EQUAL TO
57x
It might be true depending on what the x value is, but you dont know what the x value is so ...
C because the relation acts as a function no mater the 2 items
2x-7 * x
----------- =. 100^2= 10000
2
2x^2-7/2= x^2-7/2
x^2-7/2=10000
x^2 = 20007/7
7 - 3 1/4 = (turn mixed number to improper fraction
7 - 13/4 = (common denominator is 4)
28/4 - 13/4 =
15/4 or 3 3/4 gallons remain in the tank
