you have to know what x and s are because they are variables.
=7(x+s)
To find the positive number ( x ) that, when added to its reciprocal ( \frac{1}{x} ), gives the maximum sum, we can express the sum as ( S = x + \frac{1}{x} ). By using calculus, we can determine that this function reaches its minimum at ( x = 1 ), which means that the maximum sum occurs symmetrically around that point. Therefore, the maximum sum ( S ) occurs at ( x = 1 ), giving ( S = 1 + 1 = 2 ).
There is a formula to calculate this sum. It is, S = ½n(n + 1) In this question, n = 25 so the sum of the numbers from 1-25 is, ½ x 25 x 26 = 325
x-7
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
=7(x+s)
The value of s minus the sum of t and g, minus the sum of m and x, is s - (t g) - (m x).
To find the positive number ( x ) that, when added to its reciprocal ( \frac{1}{x} ), gives the maximum sum, we can express the sum as ( S = x + \frac{1}{x} ).

There are two solution: -3 and +2.
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
there are different ways of writing dis program... 1+x+(x*x)+(x*x*x*)+....has a formula for its sum... the sum for a geometric series with a as initial value and x as common ratio is (a*(pow(r,n)-1))/(r-1).... where a=1;r=x.. accept the values of x and n through keyboard remember to take x as a float value!! apply the formula and be careful about the parantheses. happy programming!!!
s=sample standard deviation s=square root (Sum(x-(xbar))2 /(n-1) Computing formula (so you don't have to find the mean and the distance from the mean over and over): square root(Sxx /(n-1)) Sxx= Sum(x2) - ((Sum(x))2/n)

2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
the sum equals x+10
To find the sum of x and y, you simply add the two variables together: sum = x + y. If you have specific values for x and y, you can substitute them into this equation to calculate the sum. Otherwise, the sum remains expressed as x + y.
