Math question time! grade: 6
a teacher asked her students to create an algebraic expression with only subtraction by only getting the answer. the answer given was 3. what is one algebraic expression that it can be?
rewards for completing problem correctly: 15 points (maybe even brainliest! )
explanation has to be provided! good luck!

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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.
