Substituting y=6x+2 into equation 3y - 18x =12 looks like:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side
We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...

Answer:
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)
Step-by-step explanation:
Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:
![cos(C) = \frac{7}{8}](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%20%5Cfrac%7B7%7D%7B8%7D%20)
![cos(C) = 0.875](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%200.875%20)
![C = cos^{-1}(0.875)](https://tex.z-dn.net/?f=%20C%20%3D%20cos%5E%7B-1%7D%280.875%29%20)
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)

Divide sales tax amount over the item's cost
23.1 / 330 = 0.07
Therefore the sales tax is 7%
