Chaunae has eaten 64 of her 128 total Jolly Ranchers. She eats 8 per day. Which equation could be used to determine how many days it'll take her to eat all her Jolly Ranchers (if d represents the number of days)?
1. 128 – 8d = 64
2. 64d = 128
3. 64 – 8d = 128
4. 8d + 64 = 128

Teddy bear is streaming on Twitch (playing Minecraft) over a 4-hour period and gains 272 viewers. Which equation represents the relationship between t, the number of hours they've been streaming, and v represents the number of total viewers.
1. v = 272/t
2. v = t/68
3. v = 68t
4. v = 272t
3 – because they gain 68 viewers per hour!

Each set of three numbers represents the lengths, in units, of the sides of a triangle. Which set can not be used to make a triangle?
- 7, 6, 14
- 4, 4, 4
- 6, 6, 2
- 7, 8,13
1 Because 7 + 6 = 13, and that's shorter than the longest side.
