Answer:
The answer is 3n
Step-by-step explanation:
Since the expression has two numbers with the same variable, they are able to be combined.
We will subtract 2n from 5n, so 5n - 2n.
This results us with <u>3n</u>, since 5 - 2 equals 3.

5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.
3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.
Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is
(3 L) / (8 L) = 0.375 = 37.5%
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
Nth term of a geometric sequence is given as:
 ...(1)
 ...(1)
Plugging n = 9, a = 3 and r = 2 in the above equation, we find:

 ... (2)
... (2)
Comparing equations (1) & (2), we obtan:
(n - 1) = 8
