Answer:
adult $8.00
child $5.50
Step-by-step explanation:
Let the price of 1 adult ticket = x.
Let the price of 1 child ticket = y.
2x + 4y = 38
3x + 3y = 40.5
Multiply the first equation by 3. Multiply the second equation by -2. Then add them.
          6x + 12y = 114
(+)      -6x - 6y = -81
-----------------------------
                   6y = 33
y = 33/6
y = 5.5
2x + 4y = 38
2x + 4(5.5) = 38
2x + 22 = 38
2x = 16
x = 8

The GCF (greatest common factor) of both of these numbers is 4, so if you divide the numerator and denominator by 4, you get 3/5.
        
                    
             
        
        
        
The correct answer would be -4
explanation: 
2x-5<-12, add 5 to both sides so then you get 2x<-8, then divide by two, x<-4.
