Answer:
tell him tell him dphones are trash and slow
Step-by-step explanation:
Try making a grid like this. Apologies for the terrible drawing and handwriting. It represents all possible results of rolling two dice and summing their values. The blue column and yellow row represent the values of each die, and the green numbers reptesent their sums.
First, you can see that there are 36 possible values. Second, it's easy to see how many results are greater than 9, since they're all in one corner. And last, you can see just how many are even and how many are odd. Remember to reduce your fractions in the end.
It would take him 9 hours to drive 522 miles since if you divide 638 with 11 you would get 58 and if you divide 522 with 58 you'll get 9.
