The way to write out the difference of 9 and a number is n-9.
a is a number which is twice as 4
9-n
9-n
X-9
1
I don’t know
9n
N
11
abs(9 - n) which is 9 - n if 9 ≥ n and n- 9 if 9 ≤ n
n - 7 = 9 n = 16
9 - n
1/9 * (n - 15)the product of one-ninth and the difference of a number and fifteen:Let n = the number1/9 * (n - 15)
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.
abs(n - 6) < 9.
Abs(9 - n)
2*abs(2-n) = 9
let the number be 'm' & 'n' m + n = 17 m - n = 1 Add 2m = 18 m - 18 / 2 = 9 Substituting 9 - n = 1 9 - 1 = n n = 8 So the two numbers are '8' & '9'.
7 - n
8-n
suppose "n"= a number so : n - 6 it will "-" because it's said DIFFERENCE .
