The answer is 44 chickens and 28 rabbits.
We have a system of two equations.
x - the number of rabbits
y - the number of chickens
Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.
Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.
Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
Answer:
Peripheral
Explanation:
The nervous system is divided into the central nervous system (CNS) & peripheral nervous system (PNS). The brain and the spinal cord comprise the central nervous system. The peripheral nervous system serves the rest of the body and they branch from the spinal cord. Ii is in the peripheral nervous system that you'll find motor and sensory neurons. The sensory neurons take information to the CNS to be processed. After processing information, the CNS sends back information through the motor neuron of the PNS indicating which action to be taken based on the ‘input’ information.
