Jackson decides to track how far from home he will be throughout the day, starting right after school. BAHS is 11 blocks from home. From school, he travels in the opposite direction from home, going 2 blocks every minute. When he's 35 blocks from home, he decides he's gone far enough. For how long has he been walking when he decides to go home?
12 minutes

Ms. Mack loves playing Apex. She fires at N00bSauce at a rate of 180 damage over 4 seconds. N00bSauce fires back at her at a rate of 200 damage over 5 seconds. Who deals more damage per second, and how much damage per second do they deal?
Ms. Mack deals 45 damage per second, while N00bSauce deals 40 damage per second. Of course Ms. Mack deals more damage!

Surprisingly, there were no fouls in Saturday's Basketball game, so all points were either 2-pointers or 3-pointers. In total, the winning team scored 88 points. Write an equation to represent the number of 2-pointers (x) and 3-pointers (y) that were made.
2x + 3y = 88
