Camille spent 22 minutes and 30 seconds opening presents.
Since Camille had a very fun birthday party with lots of friends and family attending, and the party lasted for 3 hours, and she and her friends played games for 3/8 of the time, ate pizza and cake for 50% of the time , and spent the remainder of the time opening presents, to determine the amount of time spent opening presents the following calculation must be performed, posing the following linear equation:
Total time - time spent on other activities = time spent opening presents
- 3 - (3 x 3/8) - (3 x 0.5) = X
- 3 - 1.125 - 1.5 = X
- 3 - 2.625 = X
- 0.375 = X
- 1 = 60
- 0.375 = X
- 0.375 x 60 = X
- 22.5 = X
Therefore, Camille spent 22 minutes and 30 seconds opening presents.

3,400 since 81,600÷24= 3,400.
You have to distribute it or use FOIL (if u know that method). This is basically factoring.
for instance:
(2x-9)×(x+4)
first: 2x × x = 2x^2
second: 2x × 4 = 8x
third: -9 × x = -9x
forth: -9 × 4 = -36
now combine like terms.
2x^2 + 8x -9x - 36
(8x and -9x are like terms)
(add the two together, which is -1x or -x)
2x^2 -x -36 is ur answer
now do this same method for the rest
Answer:
6 times 6 times 6
Step-by-step explanation:
6 x 6 = 6²
Therefore 6 x 6 x 6 = 6³
