Seki and raina sold a total of 162 candles for their school fund-raiser. if seki sold three boxes of candles and raina
sold two boxes plus twelve single candles, how many candles come in each box?

30 candles in each box

Step-by-step explanation:

3x+2x+12=162        Where x is the number of candles per box

5x+12=162              Combine like terms

5x=150                   Subtract 12 from both sides

x=30                       Divide both sides by 5

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.
