For this problem we must set up some fractions in an equality. First, we put number of people in the numerator and number of hours in the denominator. After this we can plug in 24 to the numerator of the first fraction and 4 to the denominator of the first fraction (24/4). We then set the two fractions equal to each other and put 18 in the numerator of the second fraction and the variable X and the denominator of the second fraction (18/x). Lastly we cross multiply and then divide leaving X alone. This will be our answer. Therefore the answer is 3 hours.
Answer:
175 minutes
Step-by-step explanation:
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes
Answer: its either A or C, but im p sure its C
Answer:
B
Step-by-step explanation:
Given
x² - 12x + 35
Consider the factors of the constant term ( + 35) which sum to give the coefficient of the x- term
The factors are - 5 and - 7, since
- 5 × - 7 = + 35 and - 5 + - 7 = - 12, hence
x² - 12x + 35 = (x - 5)(x - 7) → B
