15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
5
Three pairs of numbers with a GCF of 5 are: 5 and 10, 10 and 15, and 5 and 15.
-10
Average(5, 10, 15) = (5 + 10 + 15)/3 = 30/3 = 10
5 10 15 10 5
Yes, 10 + 5 = 15.
10 less than 15 = 15 - 10 = 5
10 and 5 10+5=15 10-5=5
The GCF is 5.
-5 - 10 = -15
