Pia uses 6 cups of sugar to make 8 pies. at that rate, how much sugar will it take to make 12 pies?

9 cups

Step-by-step explanation: If 6 cups make 8, then 3 cups make 4. so, 9 cups would make 12 pies

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

m∠a is 90°

m∠b is 40°
