Answer:
![2\frac{1}{2}\ liters](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%5C%20liters)
Step-by-step explanation:
step 1
Convert mixed number to an improper fraction
![1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B1%2A5%2B1%7D%7B5%7D%3D%5Cfrac%7B6%7D%7B5%7D)
step 2
Using proportion
![\frac{3}{(6/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=3/(6/5)\\ \\x=15/6\ liters](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B%286%2F5%29%7D%5Cfrac%7Bliters%7D%7Bdoors%7D%20%3D%5Cfrac%7Bx%7D%7B1%7D%5Cfrac%7Bliters%7D%7Bdoor%7D%5C%5C%20%5C%5Cx%3D3%2F%286%2F5%29%5C%5C%20%5C%5Cx%3D15%2F6%5C%20liters)
step 3
Convert to mixed number
![\frac{15}{6}\ liters=\frac{12}{6}+\frac{3}{6}=2\frac{1}{2}\ liters](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B6%7D%5C%20liters%3D%5Cfrac%7B12%7D%7B6%7D%2B%5Cfrac%7B3%7D%7B6%7D%3D2%5Cfrac%7B1%7D%7B2%7D%5C%20liters)
Answer:
y = -12
Step-by-step explanation:
any equation with only an x or y value present will either be a vertical or horizontal line. Because the y axis is vertical, a line that is present on y=-12 will sit on y=-12 forever, and therefore be a horizontal line
