N=20
20 = 5 + n/3 15 = n/3 n = 45
N equals 20. You would take 5 and multiply it by 16, and then you get 80. Take 80 and then divide by 4, and then you get 20. Here is what the equation would look like. 5x(16)=4n 80= 4n Then divide each side by a four. N=20. There you go.
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4
n + 1/4 = 9/20 n + 5/20 = 9/20 n = 4/20 = 1/5
This is what is called equations, which is Algebra. Here is how to do this calculation. 5n=20 5 and n multiply together, so 5 times n = 20. So 5 times ? = 20. To write this, you should write: 5n=20 n=20/5 n=4 So the answer is 4. J.H.
If you mean -17 = 15n -20 then the value of n is 1/5
if n=4 then n+1 would be 4+1 which equals 5
5
1*20 = 20 Thus n = 20
when n = 0 it equals -25 when n = 1 it equals -36 when n = 2 it equals -39 etc
n = 20
