You can put this solution on YOUR website! N% of 18 is 63. To the nearest tenths, N =
18*n = 63
n = 63/18
N% = 63*100/18

The sum of two consecutive odd numbers plus the next even number is 926. Write an algebraic equation that can be used to solve this problem.
n + n+2 + n+3 = 926
Answer by jim_thompson5910(35256)  (Show Source):
You can put this solution on YOUR website! (N/100)*18 = 63
N/100 = 63/18
N/100 = 3.5
N = 3.5*100
N = 350
So N = 350

"The sum of two consecutive odd numbers plus the next even number is 926"
translates to
(2x + 1) + (2x + 3) + (2x + 4) = 926

You can put this solution on YOUR website! N% of 18 is 63. To the nearest tenths, N = ?
------
(N/100)*18 = 63
18N = 6300
N = 113400

The sum of two consecutive odd numbers plus the next even number is 926. Write an algebraic equation that can be used to solve this problem.
1st odd: 2x-1
2nd odd: 2x+1
Next even: 2x+2
---------
Equation:
4x + 2x+2 = 926
6x = 924
x = 154
------
1st odd: 2x-1 = 307
2nd odd: 2x+1 = 309
Next even: 310

You can put this solution on YOUR website! The sum of two consecutive odd numbers plus the next even number is 926. Write an algebraic equation that can be used to solve this problem.
We have 3 unknown numbers.
odd number one odd number two and the next even number.
let first odd number be represented by x
The second odd number is x + 2
and the next even number is x + 3
x + x + 2 + x + 3 = 926 *
(first odd ) ( next odd) + ( next even) = 926
combining lime terms we get 3x + 5 = 926
- 5 = -5
__________________
3x = 921
x = 307
Then x + 2 is next odd number = 309
and the next even number is = 310
307 + 309 + 310 = 926
* Since odd numbers are all separated by 2
( for ex 5,7,9,11)
Then if x is first odd number, we have to add 2 to get the
NEXT(consecutive) odd number.
