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
If it is 4 1/2, you can make 10 four and a half inch strips with no remainder
The answer is: b) a = 63°
2m + 6 = 2(2m + 3) -2m
2m + 6 = 4m - 2m + 6
2m + 6 = 2m + 6
True.
