n - 15 < 48 Add '15' to both sides n - 15 + 15 < 48 + 15 n < 63
The answer is 3. How do you find this? List the factors of both 48 and 15: 48: 1,2,3,4,6,8,12,16,24,48 15:1,3,5,15 Then take the greatest common factor, which in this case is 3. :)
15 and 5 both go into every multiple of 15 .
the answer is 11. b = 11 b is unknown value. We need to find out what is "b" to make the statement true. write the given statement 3b + 15 = 48 Subtract 15 from both sides 3b + 15 -15 = 48 - 15 3b = 33 Divide both sides by 3 3b/3 = 33/3 b = 11
Both 15 and 20 can go into 60, as they are both factors of that number.
