Answer:
y = 120x
Step-by-step explanation:
y=mx + b is what we need where m is the slope and b is the y-intercept.
the train travels at about 120km/hour, thus the slope is 120. 
y= 120x +b. to find the y intercept plug in any coordinate. 
240 = 120(2) +b. you find that the y-intercept is 0. 
final equation: y= 120x

0.75x + 0.5y = 25.....and she doesn't want any licorice....so x = 0
0.75(0) + 0.5y = 25
0.5y = 25
y = 25/0.5
y = 50....she can get 50 cherry candies 
        
                    
             
        
        
        
Answer:
16x^2 t^5
Step-by-step explanation:
 2 * 16 = 32
x * x^2 = x^3
t^3 * t^5 = t^8
2x t^3 * 16x^2 t^5 = 32x^3 t^8
