It is 17 because (17+19)/3 = 12
the answer is 9
the number is 11
19 + 3 = 22
-24
Reverse the operations. Start with 19, subtract 4, which leaves 15. Divide 15 by 3, and that is the number you began with.
If sum of digits of a number is divisible by 3 then the number is divisible by 3. Sum of digits = 1+3+4+5+6 = 19 and 19 is not divisible by 3. So 13456 is not divisible by 3.
It is 17 because (17+19)/3 = 12
5x + 6
The numbers are 19 and 5
3 + 23 7 + 19 13 + 13
the answer is 9
what is 4 times the sum of a number squared and 3
19 and 3; 17 and 5.
10n = -30 n = -3
-3
That number would be 3
