Answer:
255
Step-by-step explanation:
EXPLANATION We are looking for the number of adult tickets sold. number of adult tickets sold =x We are given that there were 61 more student tickets sold than adult tickets. number of student tickets sold =+x61 The total number of tickets sold was 511. 
 
        
             
        
        
        
divide the base by the sin of the opposite angle
 base = 2
opposite angle = 30 degrees
2/sin(30) = 4
 x = 4
 
        
             
        
        
        
Answer:
fourth option
Step-by-step explanation:
Given
3x < - 9 ( divide both sides by 3 )
x < - 3
solution set is { x | x < - 3 }
