Answer: 2000/25 = 80 tiles
Step-by-step explanation: 
Date: s=20
equation of surface area of a cube prism: surface area = 6s*2
the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2
subtitute values: surface area = 5(20)*2
= 5(400)
surface area = 2000
area of 2 tile is 5*2 = 25 square inches
2000/25 = 80 tiles
 
        
             
        
        
        
Answer:
4 weeks= $57
45+3(4)
45+12=57
10 weeks= $75
45+3(10)
45+30=75
15 weeks= $90
45+3(15)
45+45=90
20 weeks=$105
No there is not enough money because you are $20 short after 20 weeks. You need to wait 7 more weeks

<span>There are 4 EQUAL pieces. 
To build 1 whole you must add together 4 pieces or compose the fraction with all four pieces 1/4 + 1/4 + 1/4 + 1/4 = 4/4 or 1 whole.</span>
