Answer:
LM+MN=LN
3x-5+x+7=17
4x=17+5-7
4x=15
x=15/4=3.75
LM= 3x-5=3*3.75-5=6.25
Step-by-step explanation:
 
        
             
        
        
        
You could solve it ( without a graph) in 2 easy ways :
1 use the equation that you have written in pencil and solve for y 
y=3=-x+4
y=-x +1
Or you could use the point slop form after you find the y intercept y=mx+b 
-3=4(-1)+b 
b= 1
So the answer would be y= -x +1 
Hope this help of it does feel free to give the brainliest 
        
             
        
        
        
Answer:
8 flowers in each bunch
Step-by-step explanation:
From this information, we can make the equation:

Where  is the number of flower in each bunch.
 is the number of flower in each bunch.

<em>Add 46 to both sides</em>

<em>Divide both sides by 23</em>

There are 8 flowers in each bunch.
 
        
                    
             
        
        
        
The answer is C 
adult: x
student: y 
x+y=120
6x+4y=560
