Let x = number of years between 1990 and 2000.
Rainbow smelt:
Initial population = 227
Average yearly rate of change = -19.76
The linear function that models the population is
y₁ = 227 - 19.76x
Bloater fish
Initial population = 1052
Average yearly rate of change = -92.57
The linear function that models the population is
y₂ = 1052 - 92.57x
When the two populations are equal, then y₁ = y₂.
That is
227 - 19.76x = 1052 - 92.57x
(92.57 - 19.76)x = 1052 - 227
72.81x = 825
x = 11.33 years
= 11 years, 0.33*12 months
= 11 years, 4 months
Add x to 1990 to obtain the year April 2011.
Answer:
x = 11.33 years.
This occurs in April 2001.

The charge on each house is 8 units
Answer:
14
Step-by-step explanation:
We are given with two 
numbers whose first 
are same.
It is given that their sum is 
adding the last two corresponding digits gives,
Now adding the rest,
to get 
should not give anything to carry as that will make A in decimal to satisfy the addition.
Therefore,
Thus 
And finally,
Thus 
Now simplifying
Thus 
is the answer.
