if you put in what the problem equals then it can be answered
30 + 30 + 30 + 30 + 30 + 30 = 180
12/n+7m=30 12/6=2 + 7x4=28
2 plus n is the true one, but 1 plus n is not?
4!
(n2 + n)/2 1+2+3+4+5+n= 15+n
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
N+18=30. Subtract 18 both sides N=12
It depends on the value of n.
1. n + 3*5 = 30 2. n + 15 = 30 3. n + 15 = 30 - 15 -15 n = 15
N=3.
It is a linear equation in one variable, n.
n = 5 so both sides are equal
To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
The sum of 2n, for n= 0 to 29.
If the question means solve 1+2+...+60 then 1+2+...+n = n(n+1)/2 for any integer n>0 So for n= 60 the sum is 60*61/2 = 30*61 = 1830
If you mean -5(6n+6) = 30 then -30n -30 = 30 and so n = -2 when evaluated
n plus 15.n plus 15.n plus 15.n plus 15.
