Answer:

Step-by-step explanation:

Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.

Write it out in a line: 3m + 12 - 8m -2

Simplify: -5m +10

Divide by -5 again to simplify further: m - 2

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!
