Hi!
Let's find how much bacteria it grows per hour.
2400 - 2000 = 400
bacteria per (divided by) hour
400/6 = 66.7
After 16 hours...
66.7 x 16 = 1067.2
Plus the original amount of bacteria
1067.2 + 2400 = 3467.2
The answer is 3067.2
Hope this helps! :)

Answer:
20%
Step-by-step explanation:
25 divided by 5 = 5
Convert to decimal
0.20
Convert to percentage
20%
Log (5) + log (3) = log (15)
Simplify both sides if needed. The left-hand side needs simplification.
4(x - 6)

-2x + 6
4x - 24

-2x + 6
All is left to do is add and subtract to get the x variable all alone.
4x - 24

-2x + 6
6x - 24

6 <-- Add 2x to both sides
6x

30 <-- Add 24 to both sides
x

5 <-- Divide both sides by 6
In order to be in the solution set, x has to be less than or equal to 5.
In interval notation: [5, -∞)
The two answers are -4 and 4, because 0-4 is -4 and 0+4 is 4. Hope this helps
