Answer:
3
Explanation:
(1/3x-1/6y)×18=4×18 ⇒ 6x-3y=72
6x-ay=8 if a=3 ⇒ 6x-3y=8
72≠8
a=3 ⇒ system has no solution
Answer:
4
Explanation:
Since it's a flippy number, we can set each digit into ababa
Since it can be divisible by 15, which means it can be divisible by both 5 and 3.
Since it is divisible by 5, the last digit will be either 0 and 5, but it cannot be 0 because 0 cannot be the first digit, so last digit must be 5.
So, ababa --> 5b5b5
It can also be divisible by 3. According to de divisibility rule of 3, if the sum of all digit is divisible by 3 then the number is divisible by 3.
Sum of all digits = 15 + 2b
it's divisible by 3 when b = 0,3,6,9
The answer is 4.
There are 4 such number.
