Math I need help with it elana went to the store where you can scoop your own popcorn and buy as much as you want. She bought 10 ounces spicy popcorn for $2.50

how much dose popcorn cost per ounce

each ouce is worth 25 cents

solution

in order to solve this you need to create proportions so

10 ounces

per $2.50

well you want this to be a unit rate so you would have

10 ounces  =  1 ounce

2.50                      x

to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...

2.50/10 which is equal to 0.25.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
