Answer:
A. 10+10+5x=80 or 20+5x=80
B. Disagree, After the pay for each person to get in the have 60 dollars left. Each ride costs 5 dollars. 60 divided by 5=12 and each of them would need a ticket, so they could only ride 6 rides/
C. 20/5=4=they could by an additional 4 tickets, each would need a ticket so they could ride 2 more rides each
Step-by-step explanation:
80-20=60
60/5=12
 
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:
Triangle BDC is a right triangle (If you dont understand I can explain in depth).  Since it's a right triangle, we can use the pythagorean theorem to find the length of BD.  The pythagorean theorem states that the length of the smaller legs squared = the longest side squared.  So we can set up the equation  +
+ =
= where x is the length of the missing side (BD).  If we were to solve for x, (I think you should know how to do this but if not I can explain), you get 12
 where x is the length of the missing side (BD).  If we were to solve for x, (I think you should know how to do this but if not I can explain), you get 12
 
        
             
        
        
        
Answer:
∠C = 80 ° ; ∠ T = 40°.
Step-by-step explanation:
Triangle CRS is isosceles because it has two sides of equal length. (CR and CS are radii).
An isosceles triangle has also two equal angles, which means that ∠CRS= ∠CSR.
Therefore, ∠C = 80 ° (180° – 50° - 50°)  because the sum of angles in a triangle is 180 degrees.  
∠C is the central angle of the arc RS.
∠ T is the inscribed angle of the arc RS.
An inscribed angle is half of a central angle that subtends the same arc on the circle, so the inscribed angle ∠ T is half of the central angle ∠C. Since ∠C = 80 °, we can easily determine the measure of ∠ T:  
80° divided by 2 is 40°.
