Circle the best answer, or write your answer on the line.
Ari's bean plant is 5 cm and grows 3 cm a week; the pea plant is 11 cm and grows 1 cm a week. Which equation shows when they match after w weeks?
- 3w + w = 5 + 11
- 5w + 3 = 11w + 1
- 3w + 5 = w + 11
- 3w + 11 = w + 5
Bo is on page 20 of a comic, reading 15 pages a day, and on page 60 of a novel, reading 5 a day. Which equation tells when the page numbers match after d days?
- 20d + 15 = 60d + 5
- 15d + 5d = 20 + 60
- 15d + 20 = 5d + 60
- 15d + 60 = 5d + 20
Esme's red kite is at 6 m, climbing 4 m a minute; the blue kite is at 18 m, climbing 1 m a minute. Which equation shows when they are level after x minutes?
- 6x + 4 = 18x + 1
- 4x + x = 6 + 18
- 4x + 18 = x + 6
- 4x + 6 = x + 18
Jun's sunflower is 8 cm and grows 5 cm a week; the bean plant is 20 cm and grows 2 cm a week. Which equation tells when they are equal after w weeks?
- 8w + 5 = 20w + 2
- 5w + 20 = 2w + 8
- 5w + 8 = 2w + 20
- 5w + 2w = 8 + 20
Kira's sprout is 2 cm and grows 4 cm a week; the class plant is 17 cm and grows 1 cm a week. After how many weeks are they equal?
Luz's sticker book has 10 stickers and gains 7 a day; the card box has 34 cards and gains 3 a day. After how many days do they match?

Noah's bean plant is 1 cm and grows 8 cm a week; the pea plant is 26 cm and grows 3 cm a week. After how many weeks are they equal?
Tala's red kite starts at 9 m and climbs 4 m a minute. Solving 4x + 9 = x + 24 gives x = 5. How high is each kite then, in m?
Zee's sunflower starts at 2 cm and grows 6 cm a week. Solving 6w + 2 = 2w + 22 gives w = 5. How tall is each plant then, in cm?
