Answer:
x =
Step-by-step explanation:
Given
ax + 3x = bx + 5
Collect terms in x on the left side by subtracting bx from both sides
ax + 3x - bx = 5 ( factor out x on the left side )
x(a + 3 - b) = 5 ( divide both sides by (a + 3 - b ))
x =

Answer:</h2><h2>The number of animals of the species will be left in 2025 = 2519 animals</h2>
Step-by-step explanation:
The number of animals of a certain species in 1980 = 20000
The rate of decrease each year = 4.5 %
The number of animals left in 2025 = ???
The number of years between 1980 and 2025 = 45
By formula of depreciation,
where Pn is the population in 2025
P is the population in 1980
R is the rate of decrease in population
Substituting the values in the equation, we get
=
=2518.7 = 2519 species.
Step-by-step explanation:
I don't know the answer to that.
