drove 1h 45 min
break 15 min
drives 1h 20 min
1h 45min+1h 20 min+15min=3h 20min
3h 20 min=3 1/3h
3 1/3h*75 km/hr=<u>250 km</u>
 
        
             
        
        
        
Im assuming your supposed to find like terms soo... as my final answer i got 11m-3n-13
        
             
        
        
        
Answer:
Slope is 1/4
Step-by-step explanation:
 
        
                    
             
        
        
        
A + c = 824                             represents number of tickets to sell
20a + 12c = 13,344                represents cost of each type of ticket
multiply equation 1 by -12 to cancel the variable 'c' and solve for 'a'
-12(a + c = 824)
-12a - 12c = - 9888
 20a + 12c = 13,344         add equations together
-----------------------------
    8a          = 3456           divide both sides by 8
     a = 432
To find children's tickets substitute adult numbers back into equation 1.
a + c = 824
432 + c = 824
subtract 432 from both sides
c = 392
adult 432, children 392
