No solution because 3rimes something doesn't equal 5
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
I think the answer to your question is It is rational and equal to 12. Hope this helps!
