PLEASE MAKE SURE THEY ARE CORRECT
1. d - 12
2. b - 90
3. a - 2 bags
4. b - 30th caller
5. b - 6x + 24
6. a - 5
7. c - 2(11x + 3)
8. d - 3
9. a - 4 days
10. d - 19
Please double check
1. d - 12 (Greatest common factor of 24 and 60 is 12)
2. b - 90 (Least common multiple of 18 and 30 is 90)
3. a - 2 bags (The greatest common factor of 18 and 6 is 6, so they can make 2 bags with 6 items in each)
4. b - 30th caller (First caller to receive both prizes will be the 30th caller)
5. b - 6x + 24 (Rewriting using distributive property: 2(3x) + 2(12) = 6x + 24)
6. a - 5 (Solving 20 - 4 x 4 + 1: 20 - 16 + 1 = 5)
7. c - 2(11x + 3) (Pulling out the greatest common factor from 22x + 6 gives 2(11x + 3))
8. d - 3 (Solving 20 ÷ (4 - (10-2^3)): 2^3 = 8, 10 - 8 = 2, 20 ÷ 2 = 10, Final calculation 10 ÷ 3 = 3)
9. a - 4 days (Julia runs every 4 days and lifts weights every 3 days, the least common multiple is 12 days, so she will run and lift on the same day after 4 days)
10. d - 19 (Solving (8 - 3) + 5 (3^2 - 3) - 1: 5 + 5(9 - 3) - 1 = 5 + 30 - 1 = 34 - 1 = 19)
