9 - n
n 7
1/9 * (n - 15)the product of one-ninth and the difference of a number and fifteen:Let n = the number1/9 * (n - 15)
7*abs(n - 10) which is 7*(10 - n) if n < 10 and 7*(n - 10) if n ≥ 10
abs(n - 6) < 9.
7 - n
abs(9 - n) which is 9 - n if 9 ≥ n and n- 9 if 9 ≤ n
7 more than the quotient of a number n and 4 is 9
The way to write out the difference of 9 and a number is n-9.
9 - n
n 7
1/9 * (n - 15)the product of one-ninth and the difference of a number and fifteen:Let n = the number1/9 * (n - 15)
n-8
3 x (7 - n)
The difference between a number and its reverse must be divisible by 9. 42 is NOT divisible by 9. There is, therefore, no such number.
7*abs(n - 10) which is 7*(10 - n) if n < 10 and 7*(n - 10) if n ≥ 10
abs(n - 6) < 9.
