N= number of tickets purchased= 5 people went to the movies
t= cost of each ticket 
$55.50 - $29.25= n * t
$55.50 - $29.25= 5t
OR
$55.50= 5t + $29.25
ANSWER: $55.50 - $29.25= 5t OR
$55.50= 5t + $29.25 (there were no equations to choose from, but it should look something like one of these). 
Hope this helps! :)
        
             
        
        
        
To the nearest thousand, because when you are estimating numbers, you always round to the nearest higher place (like the nearest tenth if comparing 26 and 18).
        
             
        
        
        
Let's cut the chit chat, and formalities. I'm not one for greetings or unnecessary niceties. 
Divide 0.5 by 10=
0.05
Check work.
0.05 x 10 = 0.5
        
                    
             
        
        
        
Answer:
SLOPE: 1
Y-Intercept: (0,4)
Step-by-step explanation:
 
        
                    
             
        
        
        
- 3x + 4y = - 11
y = 2x - 4
-3x + 4(2x - 4) = -11
-3x + 8x - 16 = - 11
5x = -11 + 16
5x = 5 
x = 5/5
x = 1
y = 2x - 4
y = 2(1) - 4
y = 2 - 4
y = -2
Solution: (1, -2)
