The way to write out the difference of 9 and a number is n-9.
abs(9 - n) which is 9 - n if 9 ≥ n and n- 9 if 9 ≤ n
8-n
7 - n
n-8
n - 8 is the expression for the difference of eight and a number.'Number' is a variable, so the variable must be a letter (in this case, 'n'). 'The difference' is going to be the subtraction symbol that is in between the 'number' and eight, so it must be n - 8. It could, of course, be 8 - n.
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
To find the value of the expression "two less than six times the difference of a number and five" when ( n = 9 ), first calculate the difference: ( n - 5 = 9 - 5 = 4 ). Then, multiply this difference by six: ( 6 \times 4 = 24 ). Finally, subtract two: ( 24 - 2 = 22 ). Thus, the value of the expression is 22.
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'.
