Answer
B and A
Step-by-step explanation:
The solution of system of equations is: x = 1.6 and y = 1.2
Step-by-step explanation:
Given equations are:
![y = 2-\frac{1}{2}x\ \ \ \ Eqn\ 1\\x-3y = -2\ \ \ eqn\ 2](https://tex.z-dn.net/?f=y%20%3D%202-%5Cfrac%7B1%7D%7B2%7Dx%5C%20%5C%20%5C%20%5C%20Eqn%5C%201%5C%5Cx-3y%20%3D%20-2%5C%20%5C%20%5C%20eqn%5C%202)
Putting
in equation 2
![x - 3(2-\frac{1}{2}x) = -2\\x - 6 + \frac{3}{2}x = -2\\x +\frac{3}{2}x = -2+6\\\frac{2x+3x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4 * 2\\5x = 8\\x = \frac{8}{5}\\x = 1.6](https://tex.z-dn.net/?f=x%20-%203%282-%5Cfrac%7B1%7D%7B2%7Dx%29%20%3D%20-2%5C%5Cx%20-%206%20%2B%20%5Cfrac%7B3%7D%7B2%7Dx%20%3D%20-2%5C%5Cx%20%2B%5Cfrac%7B3%7D%7B2%7Dx%20%3D%20-2%2B6%5C%5C%5Cfrac%7B2x%2B3x%7D%7B2%7D%20%3D%204%5C%5C%5Cfrac%7B5x%7D%7B2%7D%20%3D%204%5C%5C5x%20%3D%204%20%2A%202%5C%5C5x%20%3D%208%5C%5Cx%20%3D%20%5Cfrac%7B8%7D%7B5%7D%5C%5Cx%20%3D%201.6)
Putting x = 1.6 in equation 2
![1.6-3y = -2\\-3y = -2-1.6\\-3y =- 3.6](https://tex.z-dn.net/?f=1.6-3y%20%3D%20-2%5C%5C-3y%20%3D%20-2-1.6%5C%5C-3y%20%3D-%203.6)
Dividing both sides by -3
![\frac{-3y}{-3} = \frac{-3.6}{-3}\\y = 1.2](https://tex.z-dn.net/?f=%5Cfrac%7B-3y%7D%7B-3%7D%20%3D%20%5Cfrac%7B-3.6%7D%7B-3%7D%5C%5Cy%20%3D%201.2)
Hence,
The solution of system of equations is: x = 1.6 and y = 1.2

Answer:
i dont know i just need points for more questions sorry
Step-by-step explanation:
Multiply the number of sizes by the number of toppings. 3 * 4 = 12 different combinations.
4(x+6)
to get the area you multiply the sides and you can represent that with parentheses
hope this helps
