Let's assume
number of birds with 2 wings is x
number of birds with 4 wings is y
A nature museum has 2008 specimens of early birds
so,
![x+y=2008](https://tex.z-dn.net/?f=x%2By%3D2008)
Total of wings of 2 wings bird =2x
Total of wings of 4 wings bird =4y
The specimens have a total of 4384 wings
so, we get
![2x+4y=4384](https://tex.z-dn.net/?f=2x%2B4y%3D4384)
we can divide both sides by 2
![x+2y=2192](https://tex.z-dn.net/?f=x%2B2y%3D2192)
so, we get system of equations as
![x+y=2008](https://tex.z-dn.net/?f=x%2By%3D2008)
![x+2y=2192](https://tex.z-dn.net/?f=x%2B2y%3D2192)
we can solve for x and y
We can subtract both equations
![2008-y+2y=2192](https://tex.z-dn.net/?f=2008-y%2B2y%3D2192)
![y=184](https://tex.z-dn.net/?f=y%3D184)
![x=2008-184](https://tex.z-dn.net/?f=x%3D2008-184)
![x=1824](https://tex.z-dn.net/?f=x%3D1824)
![y=184,\:x=1824](https://tex.z-dn.net/?f=y%3D184%2C%5C%3Ax%3D1824)
so,
number of birds with 2 wings is 1824
number of birds with 4 wings is 184.............Answer
Answer:
Step-by-step explanation:
Answer:
4/10 meters
Step-by-step explanation:
Original Length : 7/10 meters
Remaining Length after cut : 3/10 meters
amount cut off = original length - remaining length
= 7/10 - 3/10
= (7-3)/ 10
= 4/10
