3 years ago<span>Let x = a certain number of cookies
5x = 3x + 20
5x - 3x = 20
2x = 20
x = 20/2
x = 10
John: 5x = 5(10) = 50
Jerry: 3x + 20 = 3(10) + 20 = 30 + 20 = 50
They both have 50 cookies a piece</span>

14 (286/20 = 14,3) you just need to remove the decimal and you can see how many times it can enter
Answer:
(A - pi r^2)/ 2 pi r= h
Step-by-step explanation:
A = pi r^2 + 2 pi rh
First subtract pi r^2 from each side
A - pi r^2= pi r^2 + 2 pi rh - pi r^2
A - pi r^2= 2 pi rh
Now divide each side by 2pi r
(A - pi r^2)/ 2 pi r= 2 pi rh / 2pi r
(A - pi r^2)/ 2 pi r= h
