Answer:
A
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = 
(x + 9) + 3 = 3 ( subtract 3 from both sides )
(x + 9) = 0 , then
x + 9 = 
= 1 ( subtract 9 from both sides )
x = - 8
Let red marbles = X.
The probability is 1 out of 5, written as 1/5
1/5 in terms of red marbles is equal to the number of red marbles divided by 5x, where 5x is the total number of marbles.
1/5 = x/5x
Now you have 5x total marbles, x red and 4x blue.
Add 5 more red and the new probability is:
(x+5)/(5x+5) = 1/3
Simplify:
3x+15 = 5x+5
Now solve for x:
Subtract 3x from both sides:
15 = 2x +5
Subtract 5 from each side:
2x = 10
Divide both sides by 2:
x = 10/2
X = 5
There were originally 5 red marbles.
