Alex and his friend kim made a one-gallon pitcher of lemonade because it was so hot. they drank 5 glasses that each 2 cups of lemonade. how much lemonade was left in the pitcher ? express the answer in two different ways . (hint: there are 4 cups in 1 quart and 4 quarts in 1 gallon.) ! i know it’s ez i’m just really tired and can’t think rn. 30 points to

we know that

4 cups of lemonade = 1 quart

1 gallon of lemonade = 4 quarts

1 gallon of lemonade = 16 cups

Step 1

 find the amount of lemonade that's left expressed in cups

5 glasses * 2 cups = 10 cups  

16 cups - 10 cups = 6 cups.  

There are 6 cups of lemonade left.  

Step 2

 find the amount of lemonade that's left expressed in  quarts:  

4 cups = 1 quart.  

(6 cups divided by 4 cups will equal the quarts.)  

6/4=1.5

6 cups = 1.5 quarts.  

There are 1.5 quarts of lemonade left.  

Step 3

 find the amount of lemonade that's left expressed in gallons  

4 quarts = 1 gallon.  

(1.5 quarts divided by 4 quarts will equal the gallon)  

1.5/4=0.375

1.5 quarts = 0.375 gallon.  

There is 0.375 gallon left of lemonade.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
