Let N = the fractionEquation: 6 = N * 15or15N/15= 6/15N = 6/15 6 is what fraction of 15
15 - n when n equals 9 = 6
15 - n/6 = n/6 - 1 16 = 2n/6 8 = n/6 n = 48 Check it. 15 - 8 = 8 - 1 It checks.
6 x n = 90 n = 15
n is 6
-24
It is an equation and the value of n is 6
Let the two numbers be 'm' & 'n' Sum = m + n = -9 Product is mn = -90 Hence m = -90/n Substitute -90/n + n = -9 Multiply through by 'n' -90 + n^2 = - 9n n^2 + 9n - 90 = 0 It is now in quadratic form ; factor (n + 15)(n - 6) = 0 n = -15 & n = 6
5/8 < n/6 6*5/8 < n ie n< 15/4 or 3.75
6 + n < 21 Subtracting 6 from both sides: n < 15
let suppose total number of nodes/computers = n the formula will be = n(n-1)/2 e.g = 6(6-1)/2 =15 links.
it is C 6 H 15 N,
