3. Students in the 7th, 8th, and 9th grade were asked whether they prefer to write in pen or pencil. 40 students prefer to write in pen. 60 students prefer to write in pencil. Create values that could represent the number of students in the 7th, 8th, and 9th grade that responded to the survey. (Three answers).

-aparri

for future students the answer is b

hope i

-lavira: )

combine all like terms then its just a 2 step equation

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.
