Set up an equation:
0.75x = 18
Divide both sides by 0.75:
x = 18/0.75
x = 24
Answer: 24

Step-by-step explanation:
B. The expression has 4 factors and 0 constants.
The factors separately are:
4
a
b
(c+3)
Factors are numbers or expressions that produce a givens product.
Looking at the expression we can rewrite it as:
4 x a x b x (c+3)
The overall value with be the product of all the factors.
The population Pa of insect A after t years is given by the equation
Pa = 1.3(1-0.038)^t
while the population Pb of insect B after t years is
Pb = 2.1(1-0.046)^t
We equate the above expressions to find the number of years t it will take the two populations to be equal:
Pa = Pb
1.3(1-0.038)^t = 2.1(1-0.046)^t
1.3(0.962)^t = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.
We can now solve for t:
(0.962)^t / (0.954)^t = 2.1/1.3
(0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
t = log (2.1/1.3) / log (0.962/0.954)
t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.
