Answer:
1/3
Step-by-step explanation:
To get no solution, you want to get rid of x and leave an incorrect equation.
In this case, we will use 1/3x.
1/3x + 2 = 1/3x - 3
We subtract 1/3x on both sides. This will cause the 1/3x's to cancel out.
1/3x - 1/3x + 2 = 1/3x - 1/3x - 3
2 ≠ -3
As we know, 2 is not 3. Therefore, there is no solution if 1/3x is used.
 
        
                    
             
        
        
        
423 = 100 + 100 + 100 + 100 + 10 + 10 + 3
hope this helps
        
                    
             
        
        
        
Answer:
r= -19/5
Step-by-step explanation:
 
        
             
        
        
        
Let 

. Then 

. By convention, every non-zero integer 

 divides 0, so 

.
Suppose this relation holds for 

, i.e. 

. We then hope to show it must also hold for 

.
You have

We assumed that 

, and it's clear that 

 because 

 is a multiple of 3. This means the remainder upon divides 

 must be 0, and therefore the relation holds for 

. This proves the statement.
 
        
        
        
Step-by-step explanation:
This is a reflection. A reflection is a transformation involving two shapes looking the same by "bouncing it off a line without coming back.( meaning a reflection goes some where else not to it original poistion.)
 Others reason why Why?
Line m is perpendicular to Line c.
B and E are equidistant from c that BC=CE.
Why the others are wrong.
While you could rotate this triangle 180 degrees, the transformation occurs about a line not a point. So using a rotation is wrong.
A translation doesnt occur about a line. 
A guide reflection doesnt work since the transformations are already mapped correctly if you do the reflection. It doesnt need a translation.
