Answer:

Step-by-step explanation:

Answer:
x = 10.6
Step-by-step explanation:
5x - 11 = 42
first +11 so,
5x = 53
then ÷5
x = 10.6
B, raise 10 to the power of both sides of the equation, and when you have 10^log(x), it just becomes x, so 10^a=10^log(987)=987
Answer:
P(0) = 7,917
Step-by-step explanation:
The population of the community is given by the following formula:

In which P(0) is the initial population and r is the growth rate.
The initial population P0 has doubled in 5 years.
This means that

Which lets us find r.



Applying the 5th root to both sides


So

Suppose it is known that the population is 12,000 after 3 years.
With this, we find P(0)
