Celine has a bottle that contains 20% of milk and the rest water. the bottle has 1 liter of water.

part a: write an equation in one variable that can be used to find the total number of liters of milk and water in the bottle. define the variable used in the equation.

part b: how many liters of milk are present in the bottle? show your work.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
