Answer:
10
Step-by-step explanation:
The current probability of picking a red ball is 
. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).
60 = 4x + 20
40 = 4x
x = 10 red balls
$6.39/3 bags = x dollars/1 bag
x dollars = $6.39/3 bags = $2.13 : 1 bag
There are 5 sides/angles in a pentagon. Formula (n-2)180 so (5-2)180 which is (3)180=540. In a regular Pentagon there is an area of 540°
