Mr. Tram was planning his trip from Dallas, TX to Detroit, MI. He knows that the total distance he needs to cover is 1620 km. He usually drives at a speed of 60 km per hour. If he is willing to drive up to 8 hours per day, how many days and how many hours will this trip take?

3 days and 3 hours

Step-by-step explanation:

lets find how many total hours he will need to spend to get to Detroit

1620/60=27

Lets find how many days will it take Mr. Tram to get to Detroit if he is willing to drive only for 8 hours each day.

27/8=3 3/8

3 days and 3 hours

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
