To determine if any three numbers from the list add up to 44, we can start by considering all possible combinations of three numbers and then calculate their sums.
Let’s examine the numbers: 21, 7, 34, 9, and 15. We can form several combinations:
- 21 + 7 + 34 = 62
- 21 + 7 + 9 = 37
- 21 + 7 + 15 = 43
- 21 + 34 + 9 = 64
- 21 + 34 + 15 = 70
- 21 + 9 + 15 = 45
- 7 + 34 + 9 = 50
- 7 + 34 + 15 = 56
- 7 + 9 + 15 = 31
- 34 + 9 + 15 = 58
After checking all combinations, we see that none of these sums equal 44. Therefore, the answer is no, three of the numbers from this list do not add up to 44.
