The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.
 
        
             
        
        
        
x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
Step-by-step explanation:
Given, 
Volume of small box = 10 cubic feet 
Volume of large box = 24 cubic feet 
Total boxes shipped = 23 
Combined volume = 426 cubic feet
Let, 
x represent the number of small boxes.
y represent the number of large boxes.
x+y=23    
10x+24y=426
x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
