1 gallon = 4 quarts
1 Quart = 2 pints
1 Pint = 2 cups
2 (amount of pints in a quart) x 5 (amount of quarts) = 10 = how many pints
10 x 2 (amount of cups in a pint) = 20
20 = how many cups in 5 quarts
7-2=5
17-16=1
You are trying to find the difference that equals 3 and is near those range of numbers.
The numbers are 11 and 14.
The next time they wil leave together is 6:00. The LCM of 8, 12, and 10 is 120. So 120/6=2, so two hours. 6:00.
A calculator can help you with that.
In radians, arcsin(sin(9π) / 7) = 0.
I think the awnser would be +7
