14 10/8 is equal to 15 2/8 which cnman simplify down to 15 1/4. So, the simplest you can get is 15 1/4. I hope this helps!
        
             
        
        
        
Answer:
1. (-2,-7)
2. (3,-9)
3. (7,-2)
4.(-3,9)
Step-by-step explanation:
Since the reflection is across the x-axis, the y-coordinate will be flipped.
Example: (-7,4) would become (-7,-4)
HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.
Example: (-7,4) would become (7,4)
 
        
                    
             
        
        
        
Answer:
11.4
Step-by-step explanation:
So we know that Triangle ACB is similar to Triangle EFD. 
This means that their sides are proportional to each other. 
We want to find x or side AB. To do so, we can set up a proportion. 
The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus: 

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus: 

Reduce the right: 

Cross multiply: 

So, the value of x is 11.4
And we're done!
 
        
             
        
        
        
Answer:
116
Step-by-step explanation:
13x-1 = 2(6x+4)
13x-1 = 12x+8
x=9
 
        
             
        
        
        
84 because 36 x 2 =72 and then 1/3 of 36 is 12 and 12+72=84
