How many 10-passenger vans will it take to drive all 95 members of the football team to an away game?
| 6 vans | |
| 9 vans | |
| 10 vans | |
| 8 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{95}{10} \) = 9\(\frac{1}{2}\)
So, it will take 9 full vans and one partially full van to transport the entire team making a total of 10 vans.
Convert b-3 to remove the negative exponent.
| \( \frac{3}{b} \) | |
| \( \frac{1}{b^3} \) | |
| \( \frac{-1}{-3b} \) | |
| \( \frac{-1}{-3b^{3}} \) |
To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.

\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?
distributive property for division |

commutative property for multiplication |

distributive property for multiplication |
|
commutative property for division |
The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Ezra buys two shirts, each with a regular price of $40, how much money will he save?
| $4.00 | |
| $10.00 | |
| $16.00 | |
| $8.00 |
By buying two shirts, Ezra will save $40 x \( \frac{40}{100} \) = \( \frac{$40 x 40}{100} \) = \( \frac{$1600}{100} \) = $16.00 on the second shirt.
