-7x+2x= what as an equivalent expression?

-5x

Step-by-step explanation:

-7x + 2x = -5x

An easier way to look at the problem:

2x - 7x = -5x

-5x

Step-by-step explanation:

First, determine which terms are alike.

Alike terms are numbers that have the same variable.

These numbers both have the same variable, (x) so just add the numbers:

-7 + 2 = -5

You got 5, so now just add back on the variable, (x), making your answer -5x.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 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.
