n + 13 = 21. n = 21 - 13
6 percent of what number is 21?
6/100 X n = 21 .06 X n = 21 n = 21/.06 = 350
If n plus 2 times 3 equals 21 what is n?
n + (2 x 3) = 21 Therefore, n = 21 - (2 x 3) n = 15
What algebraic expression can you draw from 21 less than a number divided by 4?

If the product is 80 and the sum us 21 what are the numbers?
Let the number be 'm' & 'n' Hence Product ; mn = 80 Sum ; m + n = 21 m = 21 - n Substitute (21 - n) n = 80 21n - n^2 = 80 n^2 - 21 n + 80 = 0 It is now in quadratic form to factor. ( n - 16)(n - 5) = 0 Hence the numbers are 5 & 16
What nation is in 21 n and 81 e?
21 N 81 E is India
7 times n divided 21 equals 1 what is n?
n = 3Solution:7n/21 = 17n = 1 * 217n = 21n = 21/7n = 3
What is 8 more than 13?
21 Solution: n = 13 + 8 n = 21
The product of a number and 3 is -21?
24
Which is the solution of the inequality n plus 21 is greater than or equal to 7?
n + 21 ≥ 7 Subtract 21 from both sides: n ≥ -14
38 plus n divided by 2 equals 21?
38 + (n/2) = 21 Therefore, n/2 = -17 n = -17 x 2 n = -34
How do I find the sum of 1 to 20?
The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210The sum from 1 to n is n*(n+1)/2In this case that mean 20*21/2 = 210
