21 Solution: n = 13 + 8 n = 21
Yes n-8 means 8 less than n
N = nigers but if you take half away it is a wigger
N+4=12 Then, you subtract 4 from each side N+4-4=12-4 So, N=8
21
yes
2n+8
21 Solution: n = 13 + 8 n = 21
Where the number=n: (n/2)+8.
n + 8
Yes n-8 means 8 less than n
n = 32 + 8 = 40
Let n = the original number n + 8 = another number which is 8 more than the original number Therefore, the two variable expressions are n and n+8
N = nigers but if you take half away it is a wigger
Energy levels from 3 and above can have more than 8 electrons maximum. Maximum of 2n2 electrons is possible where n is the energy level.
8c+ 1/2n
8n+6
