Whats n+8
N - 8 = 22 (:
Well, darling, 5 times the difference of a number and 8 is simply 5(n-8), where n is the mysterious number you're working with. So, if you want to find out the result, just plug in your number and do the math. Easy peasy, lemon squeezy!
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'.
Abs(n - 8) = 22
8-n
n-8
If the number is n then it is |8 - n| or abs(8 - n)
Whats 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.
4n-8
The corresponding equation, is solve n when :- 2(n - 4) = -8 2n - 8 = -8 2n = -8 + 8 = 0 n = 0
N - 8 = 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'.
Abs(n - 8) = 22
n/8 or 8/n
The difference between successive terms is 8 tn = 8n + 9 or 8(n+1)+1 where n = 1,2,3,...
