Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
 
        
                    
             
        
        
        
Multiply 13 by 3
13 * 3 = 39 miles
Hope this helps :)
        
                    
             
        
        
        
Can you please add the graph, plus the question?
        
             
        
        
        
The value of n is 4 and yz is 1 if y is between x and z i.e. if y, x and z are collinear points.
According to the given question.
We have some linear equations.
xy = 4n + 3 
yz = 2n - 7
and 
xz = 20 
Since, y is between x and z. Which means y, x and z are collinear points.
Therefore, 
xy + yz = xz
⇒ 4n + 3 + 2n - 7 = 20 
⇒ 6n -4 = 20 
⇒ 6n = 20 + 4
⇒ 6n = 24
⇒ n = 24/6
⇒ n = 4
Therefore, 
yz = 2n - 7 = 2(4) - 7 = 8- 7 = 1 
Hence, the value of n is 4 and yz is 1 if y is between x and z i.e. if y, x and z are collinear points.
