Alex and his friend Kim made a one-gallon pitcher of lemonade because it was so hot. They drank 5 glasses that each held 2 cups of lemonade. How much lemonade was left in the pitcher? Express the answer in two different ways. (Hint: there are 4cups in 1 quart and 4 quarts in 1 gallon.)

There is 0.375 gallon left of lemonade.

1.5 quarts = 0.375 gallon.  

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
