Celine has a bottle that contains 20% milk and the rest water. the bottle has 1 liter of water. part a: write an equation using 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. (5 points) part b: how many liters of milk are present in the bottle? show your work. (5 points) i will give brainliest

Let x L be an amount of milk in the bottle. The bottle has 1 L water, then it contains x+1 L of milk and water. This is all that is in bottle, then x+1 is 100% and you know that milk is 20%. You can write the proportion:

x+1 - 100%

x - 20%.

Mathematically,

In the bottle is 0.75 L of milk. The total number of liters of milk and water in the bottle is 1.75 L.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
