Answer:
440 seagulls
Step-by-step explanation:
Total number of seagulls in flock = Number of seagulls have banded / Percentage of seagulls have banded
Total number of seagulls in flock = 22 / 5%
Total number of seagulls in flock = 22 / 0.05
Total number of seagulls in flock = 440 seagulls
Answer:
x > -5
Step-by-step explanation:
4-x < 9
-x < 9-4
-x < 5
x > -5
Answer:

Step-by-step explanation:
Let's rewrite the left side keeping in mind the next propierties:


Therefore:

Now, cancel logarithms by taking exp of both sides:

Multiply both sides by
and using distributive propierty:

Substract
from both sides and factoring:

Multiply both sides by -1:

Split into two equations:

Solving for 
Add 4 to both sides:

Solving for 
Collect in terms of x and add
to both sides:

Divide both sides by e-2:

The solutions are:

If we evaluate x=4 in the original equation:

This is an absurd because log (x) is undefined for 
If we evaluate
in the original equation:

Which is correct, therefore the solution is:
