(1/2s)+(1/5x)+7
5s+2x+7
5s=2x+7
s=2/5x+7/5
(1/2(2/5x+7/5))+(1/5x)+7
1/5x+3.5/5+1/5x+7
2/5x+7 7/10
2/5x=-7 7/10
x=-19.25
(1/2s)+(1/5x)+7
1/2s-3.85+7
1/2s+3.15
1/2s=-3.15
s=-6.3
(1/2s)+(1/5x)+7
1/2(-6.3)+1/5(-19.25)+7
-3.15-3.85+7
0
In the end, it equals 0 because there were no values for x and s and since I started with just an equation with nothing on the other side, I used (by default) 0 on the other side.

What is the sum of all integers not greater than 10000 that are not divisible by 7?
This is easiest to answer by summing all the numbers 1-10000 and subtracting the sum of the multiples of 7 (7, 14, 21, ..., 9996). The sum of a series is: S = (first + last) x number_of_terms / 2 For for 1-10000, the sum is: S1 = (1 + 10000) x 10000 / 2 = 10001 x 5000 = 50005000 For the multiples of 7 the sum is: S2 = (7 + 9996) x 1428 / 2 = 10003 x 714 = 7142142 So the sum of all integers not greater than 10000 that are not divisible by 7 is: S = S1 - S2 = 50005000 - 7142142 = 42,862,858

Program to calculate the sum of first ten natural numbers?
Algorithm to find the sum of first n natural numbers:1. Read n.2. Initialize N=1.3. Initialize sum S=0.4. Calculate S=S+N.5. Calculate N=N+1.6. If N>n, then goto step 7 else goto step 4.7. Write the sum S.8. Stop.
How do you find the sum of all the integer multiples of 7 from 7 to 700?
∑7n from n = 1 to n = 100 is a shorthand method of writing :- 7x1 + 7x2 + 7x3 +...........+ 7x 99 + 7x100 This can be written as 7(1 + 2 + 3 +........+ 99 + 100) The sum (S) of a range of numbers from 1 to n is given by the formula S = 1/2 n(n + 1) And substituting the relevant numbers gives, S = 1/2 x 100 x 101 = 5050 But this now needs multiplying by 7 to give the sum of the multiples = 7 x 5050 = 35350.
If the sum of interior angle measures of a polygon is 900 degrees how many sides does the polygon have?
The polygon has 7 sides (septagon). The formula for the total degrees is D = 180 (s-2) 900 = 180 (s-2) 5 = s-2 7 = s
