A school cafeteria has 30 boxes of Wheaty Squares cereal and 20 boxes O’s cereal. Each box has the same number of ounces of cereal. Write an expression to represent the total ounces of cereal. Then simplify it to create an equivalent expression.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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.
