Answer:
39 active volcanoes.
Step-by-step explanation:
Subtract 169 (whole) from 130 (part). 9 - 0 = 9, 6 - 3 = 3, and 1 - 1 = 0. Therefore, 169 - 130 = 39
 
        
                    
             
        
        
        
Find the ticket unit cost:  divide the total paid, $324, by the number of tickets, x.  Then the form of the unit cost is
$324
--------- .
    x
This question is highly unusual in that you write "x" as the number of tickets sold, instead of a specific number of tickets.  Supposing that you'd sold 100 tickets for $324, then the unit cost would be, much more typically, a numeric ratio:
$324
----------------- = $3.24/ticket
100 tickets
 
        
                    
             
        
        
        
Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:

 Final speed of the skateboard(v) = 4 m/s
 Final speed of the skateboard(v) = 4 m/s
 
        
             
        
        
        
Answer:
-4n + 5y + 6
Step-by-step explanation:
Distribute the negative
−4n + 5y + 6
There is really no answer for this but all you have to do is to multiply the figures outside the bracket by the ones inside the brackets.
