Adjacent angles<span> are two </span>angles<span> that have a common vertex and a common side.
<OPN and <TSP have a common side but do not have a common vertex.
<OPN and <RSU do not have a common side or a common vertex.
<OPN and <QPN are adjacent angles. They have a common side and a common vertex.
<OPN and <QPS have common vertex but do not have a common side.</span>
        
                    
             
        
        
        
Answer:
One adult ticket is $4 and one child ticket is $7
Step-by-step explanation:
Make a system of equations
2x + 10y = 78
8x + 5y = 67
Solve by elimination, multiply the 2nd equation by -2
2x +10y = 78
-16x -10y = -134
Add the equations
-14x = -56
x = 4
The price of one adult ticket is $4
Plug 4 in as x to find y
2(4) + 10y = 78
8 + 10y = 78
10y = 70
y = 7
The price of one child ticket is $7
 
        
             
        
        
        
p=3h + 3u  subtract 3u from both sides
p-3u=3h   now divide both sides by 3
h = p/3 - u
 
        
                    
             
        
        
        
Midpoint =(\frac{x_{2}+x_{1}}{2},\frac{y_{2}+y_{1}}{2})
Answer:
Midpoints of line CD are (-2,2).
Step-by-step explanation:
The midpoints is given by 

As given
The endpoints of CD are C(−4, 7) and D(0,−3).
Putting values in the above


Midpoints = (-2,2)
Therefore midpoints of line CD are (-2,2).
