IF you meant n/7=4 then n=28
If you mean: n-4 = 10 then n =14
Mean = (24+25+26+28)/4 = 103/4 = 25.75
-53+n = -28 n = -28+53 n = 25
28 + N = 68 Subtract 28 from each side: N = 40
IF you meant n/7=4 then n=28
N plus 28 is a math equation. N would stand for an unknown number. You would add 28 to this unknown to find the answer.
n = 35
If you mean: n-4 = 10 then n =14
Mean = (24+25+26+28)/4 = 103/4 = 25.75
If you mean 4 and 28 then the LCM is 28
It is any one of infinitely many fractions of the form n/n where n is a no-zero integer.
Euclid found the four first even perfect numbers by using the formula (2^n -1)(2^n -1). For n = 2 he found 6. For n = 3 he found 28. Let's compute it. (2^n -1)(2^n -1) (2 ^3-1)(2^3 - 1) = (4)(7) = 28. Let's check if this is true. Factors of 28 are 1, 2, 4, 7, 14, and 28. 1 + 2 + 4 + 7 + 14 = 28. For n = 5 Euclid found 496, and for n = 7 he found 8128.
-53+n = -28 n = -28+53 n = 25
6
If you mean: -4*(n-6) = 12 then the value of n = 3
If you mean 21/28 then it is 3/4
