The computation shows that the price of each game is $2.5 and the price of shoe rental will be $3.
<h3>How to illustrate the information?</h3>
Fron the information given, the equation will be:
s + 4g = 13
s + 8g = 23
4g = 10
g = 2.5
Therefore, the price of each game is $2.5
The price of shoe rental will be:
s + 4g = 13
s + 4(2.50) = 13
s = 13 - 10.
s = 3

Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :
![{(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}](https://tex.z-dn.net/?f=%20%7B%28x%20-%20h%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%28y%20-%20k%29%7D%5E%7B2%7D%20%20%3D%20%20%7Br%7D%5E%7B2%7D%20)
Given, the equation of circle
![{(x + 2)}^{2} + (y - 3) ^{2} = 25 = {5}^{2}](https://tex.z-dn.net/?f=%20%7B%28x%20%2B%202%29%7D%5E%7B2%7D%20%20%2B%20%28y%20-%203%29%20%5E%7B2%7D%20%20%3D%2025%20%3D%20%20%7B5%7D%5E%7B2%7D%20)
By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)

8.25 or 9 .....................................................................................
The answer is 8.8 because the number 3 can be round off to 0
This equation involves no x variable, so I assume you want to solve this for D.
First of all, you can divide both sides by 0.785 to get
![0.785D^2 = 0.54 \iff \dfrac{0.785D^2}{0.785} = \dfrac{0.54}{0.785} \iff D^2 = \dfrac{0.54}{0.785} =](https://tex.z-dn.net/?f=%200.785D%5E2%20%3D%200.54%20%5Ciff%20%5Cdfrac%7B0.785D%5E2%7D%7B0.785%7D%20%3D%20%5Cdfrac%7B0.54%7D%7B0.785%7D%20%5Ciff%20D%5E2%20%3D%20%5Cdfrac%7B0.54%7D%7B0.785%7D%20%3D%20)
Since the right hand side is positive, the equation make sense (otherwise we would be asking a square, i.e. a positive number, to equal a negative number). So, we can extract the square root from both sides:
![D^2 = \dfrac{0.54}{0.785} \iff \sqrt{D^2} = \pm\sqrt{\dfrac{0.54}{0.785}} \iff D = \pm\sqrt{\dfrac{0.54}{0.785}}](https://tex.z-dn.net/?f=%20D%5E2%20%3D%20%5Cdfrac%7B0.54%7D%7B0.785%7D%20%5Ciff%20%5Csqrt%7BD%5E2%7D%20%3D%20%5Cpm%5Csqrt%7B%5Cdfrac%7B0.54%7D%7B0.785%7D%7D%20%5Ciff%20D%20%3D%20%5Cpm%5Csqrt%7B%5Cdfrac%7B0.54%7D%7B0.785%7D%7D)
