2(x-5)=20
Divide both sides by 2  (division of property equality) 
x - 5 = 10
Add 5 to both sides     (addition of property equality)
x = 15
Answer
x = 15 is the solution

Given an integral  .
.
We are required to express the integral as a limit of Riemann sums.
An integral basically assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinite data. 
A Riemann sum is basically a certain kind of approximation of an integral by a finite sum. 
Using Riemann sums, we have :
 =
= ∑f(a+iΔx)Δx ,here Δx=(b-a)/n
∑f(a+iΔx)Δx ,here Δx=(b-a)/n
 =f(x)=
=f(x)=
⇒Δx=(5-1)/n=4/n
f(a+iΔx)=f(1+4i/n)
f(1+4i/n)=![[n^{2}(n+4i)]/2n^{3}+(n+4i)^{3}](https://tex.z-dn.net/?f=%5Bn%5E%7B2%7D%28n%2B4i%29%5D%2F2n%5E%7B3%7D%2B%28n%2B4i%29%5E%7B3%7D)
 ∑f(a+iΔx)Δx=
∑f(a+iΔx)Δx=

Hence the expression of integral as a limit of Riemann sums of given integral  is 4

∑ from i=1 to i=n.
 from i=1 to i=n.

5(12.50 x 7) = 437.5
Explanation: you take the amount she makes for one hour (12.50), times it with the hours she works in a day (7), and then times it with how many days she works (5).

The answer is 4733% 
I did this by multiplying 47.33 by 100 to convert to percent.
47.33*100=4733%
