30 + x0.15=y is the first equation 
15+x0.20=y is the second equation 
Where in both x equals the amount of days it takes and y is your out come 
You can solve this problem two ways one by finding the common denominator or just multiply x until you get the same awnser between the both of them
        
             
        
        
        
The formula for area of a circle is π x r^2
r = radius = 7 cm.
Area = 7^2 x π
Area = 49π cm²

Answer:
4 cm
Step-by-step explanation:
The midpoint segment has length ...
... L = AB/2 + BC + CD/2 = 16 cm
The entire segment has length ...
... AD = AB + BC + CD = 28 cm
If we subtract AD from 2L, we have ...
... 2L - AD - 2L = 2(AB/2 +BC + CD/2) - (AB +BC +CD) = 2(16 cm) -28 cm = 4 cm
... AB +2BC + CD -AB -BC -CD = 4 cm . . . . remove parentheses
... BC = 4 cm . . . . simplify
