If a number is divisible by 3 and 5 then it is divisible by 15
2 answers:
Answer:
Yes!
Step-by-step explanation:
Besides 15 and one, 3 and 5 are the greatest common factors of 15. Those numbers are therefore divisible by any product of 15.
Example:
45
45/3 = 15
45/5 = 9
45/15 = 3
Answer:
Yes it is
Step-by-step explanation:
Since the multiplication of 3 and 5 will give 15
I.e 3 × 5 = 15
Then any number that can be divided by 3 and 5, can also be divided by 15.

Answer:
-63, 38
Step-by-step explanation:
1st number = x
2nd number = x+101
x+x+101=-25
2x=-126
x=-63
1st number = x = -63
2nd number = x+101 = 38
The solution will be x>1/6
