Answer: <u><em>188 pairs of rabbits would be produced after fourteen months</em></u>
<u><em></em></u>
Given: Newborn rabbits become adults in one month.
Each pair of adult rabbits produces one pair each month.
No rabbits die.
The Fibonacci sequence can be written as :
= 0 1 1 2 3 5 8 13 21 34 ..........................
This series can be further written as:
= 
Therefore for n = 14;
<u><em>
= 377</em></u>
Answer:
x = 0.8 y = 0.6
Step-by-step explanation:
Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.
Next plug in the value for y into the 1st equation, I got :
2x + 4 ( 2x - 1) = 4
Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.
Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1
Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.
