Answer:
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Step-by-step explanation:
Let
Number of students tickets sold = x
Number of adults tickets sold = y
x + y = 530 (1)
3x + 4y = 1740 (2)
From (1)
x = 530 - y
Substitute x = 530 - y into (2)
3x + 4y = 1740
3(530 - y) + 4y = 1740
1590 - 3y + 4y = 1740
 - 3y + 4y = 1740 - 1590
y = 150
Substitute y = 150 into (1)
x + y = 530 
x + 150 = 530
x = 530 - 150
x = 380
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
 
        
             
        
        
        
Answer:
17/3
Step-by-step explanation:
       To find the length of the arc, we have to find what fraction of the circle is the arc. To find this, we do 340/360 because there are 360 degrees in a circle, and get 17/18. Since the circumference is 6, we take 17/18 of 6 which is 17/3.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
If it's on the same line, that means that the slope from each point to the other must be the same.
Using the first given points, we can calculate the slope to be:

We can solve for y

We can double check:
