Well here are two equivalent different expressions of my making that you could use for this question.
f(x) = 2x - 7
g(x) = 3x - 28 / 2
When x = 7, these two different expressions will equate to the same value of 7. If you meant something else let me know, otherwise this is what you should put for your essay-question. 
 
        
             
        
        
        
Four different colours I believe. Because it says each ticket type will be a different colour. Therefor, adult (1), child (2), 1-day (3), 2-day (4). 
Hope this was helpful and correct! 
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
6 x 6 = 36
now to the nearest tenth it would be
36
so your answer is 36
 
        
                    
             
        
        
        
Given that <span>v=234 3√p/w (cube root)
where </span><span> 
p is the horsepower of the car and 
w is the weight (in pounds) of the car 
v is the velocity in miles per hour
p = 1311 hp
w = 2744 lb
substitute the given value to the equation to solve for the velocity
v = 234 </span><span>3√(1311 / 2744)
v = 183 miles per hour is the velocity of a car at the end of a drag race.</span>
