1) Answer: 113
3^3 + 2[64 - (3x7)]
27 + 2[64 - (3x7)]
27 + 2[64 - 21]
27 + 2[43]
27 + 86
= 113
3) Answer: (-1, 11)
Since the problem said that it was 11 points across the y-axis, you just have to replace the -12 with 11 because -12 is the y-value.
4) 5.5 quarts = 11 pints
1 quart is equal to 2 pints, so just double the amount of quarts.
5) 120 minutes (or 2 hours)
Set up a proportion and solve for the missing value. (24/x = 6/30)
6) 5 and 8
5 x 8 = 40
5 + 8 = 13
8) -8.95
1.3 + (-6) + (-4.25)
1.3 - 6 - 4.25
-4.7 - 4.25
= -8.95
