Answer:
2 hour 50 minutes
Step-by-step explanation:
Given data: Departure = 5:30 pm MST, Arrive = 9:20 pm CST
Note that MST is the time zone 1 hour before CST.
Let us convert MST into CST.
Departure = 5:30 pm MST = 6:30 pm CST
Total time travel = Departure – Arrival
= 9.20 pm MST – 6.30 pm MST
= 2 hour 50 minutes
Hence, total time travel is 2 hour 50 minutes.
What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to

and the second fraction to

. (You are dividing a negative by a negative, therefore, your answer would be a positive.
Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it :

×

.
You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it

. This, converted to a mixed fraction, makes 1

., which is the same as 1

. Your answer is the
SECOND CHOICE.
Answer: 39
Step-by-step explanation: you have to plug in -4 into each x so that would be f(-4)=2(-4)(2)+7(-4)(3)-8(-4)(2)-21(-4)+7= 39

Answer:
A=11,13,17,19 B=12,18 None=10,14,16,19 Both=15
Step-by-step explanation:
11,13,15,17,19 are all odd so they go in A
12,15,18 Are all multiples of 3 so they go in B
10,14,16,19 Are not classified so they go outside of the diagram but inside E
15 is odd and a multiple of 3 so put it in the center and not with A and B
