So the equation for the area of a circle is

First to find the radius, you would need to divide the diameter, 26, by half, which in this case its 13.
Replace the r variable with 13 and solve:


Mr edwards = Mr r x 2
Mr r = Mr p - 3 = Mr e ÷ 2. Mr p = 30
Mr e + Mr r = 81. Mr e = 54
Mr p = Mr r + 3. Mr r = 27
Mr Edwards = 2(Mr p - 3)
Mr e = 2(mr p) - 6
Mr r = [2(Mr p) -6] ÷ 2
Mr r = [2( Mr r + 3) - 6] ÷ 2
2(Mr r) + (Mr p - 3) = 81
2(Mr p -3) + (Mr p - 3) = 81
3(Mr p - 3) = 81
3(Mr p) - 9 = 81. Hope this helps!!!
3(Mr p) + 9 = 81 + 9
3(Mr p) = 90
Mr p = 90 ÷ 3
Mr p = 30
Answer:
The cost price was 500.
Step-by-step explanation:
Let x be the original price.





You have to multiply every number!!
Example: 8 x 6 x 3 x 3 x 4
Hello,
We have the function y=560+630/x
We have x as 0 making y=630
