Answer:
wiring probably.
Step-by-step explanation:
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
![9.1 = -0.2x + 10](https://tex.z-dn.net/?f=9.1%20%3D%20-0.2x%20%2B%2010)
![0.2x= 10-9.1](https://tex.z-dn.net/?f=0.2x%3D%2010-9.1)
![0.2x= 0.9](https://tex.z-dn.net/?f=0.2x%3D%200.9)
Divide both sides by 0.2.
![x=\dfrac{0.9}{0.2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B0.9%7D%7B0.2%7D)
![x=4.5](https://tex.z-dn.net/?f=x%3D4.5)
Similarly,
In option B,
![10 = 9.1 + 0.2x](https://tex.z-dn.net/?f=10%20%3D%209.1%20%2B%200.2x)
![0.9= 0.2x](https://tex.z-dn.net/?f=0.9%3D%200.2x)
![4.5=x](https://tex.z-dn.net/?f=4.5%3Dx)
In option C,
![10-0.2x = 9.1](https://tex.z-dn.net/?f=10-0.2x%20%3D%209.1)
![-0.2x = -0.9](https://tex.z-dn.net/?f=-0.2x%20%3D%20-0.9)
![x = 4.5](https://tex.z-dn.net/?f=x%20%3D%204.5)
In option D,
![9.1 – 10 = 0.2x](https://tex.z-dn.net/?f=9.1%20%E2%80%93%2010%20%3D%200.2x)
![-0.9 = 0.2x](https://tex.z-dn.net/?f=-0.9%20%3D%200.2x)
![-4.5 = x](https://tex.z-dn.net/?f=-4.5%20%3D%20x)
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
![4x+1.9=22.2](https://tex.z-dn.net/?f=4x%2B1.9%3D22.2)
It can be written as
![4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9](https://tex.z-dn.net/?f=4x-22.2%3D-1.9%2C1.9%3D22.2-4x%2C22.2-4x%3D1.9)
Therefore, the correct options are C and E.
