Multiply through the parenthesis:
6x - 3 = -51
Combine like terms:
6x = -48
Divide by 6 on both sides:
x = -8
The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the bacteria population at time t. a represent the initial population at t = 0. Since the doubling period of a bacteria population is 10 minutes, hence:

At time t = 110 minutes, the bacterial population was 800. Hence:

At 4 hours (240 minutes):

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600

Answer:
- 24 - 5x
Step-by-step explanation:
1) Remove Parentheses
-2 - 3x - 6 - 9 - 7 + x - 3x
2) Collect like terms
( -2 - 6 - 9 - 7) + (-3x+x-3x)
3) Simplify
I think it’s .2 I could be wrong but just use a calculator.
