Answer:
first, how many cups in a gallon. 4 cups/quart, 4 quarts/gallon- 16 cups per gallon
144/16= 9 gallons
The answer is 30000+2000+700+40+6
-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.
8(2+6) = 16 + 48
or
16(1+3) = 16 + 48
or
4(4+12) = 16 + 48
