If 74% are in the display, then 100% - 74% = 26% are hung on the wall.
 This means 104 cars is 26% of her collection.
 To find the total collection divide the number on the wall by the percentage of the collection:
104/0.26 = 400
The total number of her collection is 400 cars.
 
        
             
        
        
        
The total amount Ali biked was over two years. To find that amount, you add the amount he biked each year. Since he biked 261 miles in one year and c miles in the other, the total amount of miles is 261 + c. That would be the expression used to describe the total number of miles.
        
             
        
        
        
Answer:
Knowing that the object is a rectangle, and that the base is 2x the height, you could say that h=height and b=base (and the base is the same as width since the object is a rectangle) then a possible equation you could construct is 2(h+2b)
Step-by-step explanation:
For example, using this equation with numbers may look like the following:
- 2(h+2b)
- 2(21+2*21)
- 2(21+42)
- 2(61)
- =122
Hopefully I was able to help you :) I would love to hear some feedback if possible and if you were able to find a simpler way.
