Answer:
If x = 20, then y = 12.5/20 = 0.625
Step-by-step explanation:
The pertinent relationship is y = k/x, where k is the constant of proportionality.
Subbing 5 for y and 2.5 for x yields 5 = k/2.5, so k = 12.5.
Then the specific relationship fit to this problem is y = 12.5/x.
If x = 20, then y = 12.5/20 = 0.625
Answer: Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
Step-by-step explanation:
Let x = Weight of Charles
y = Weight of dog.
As per given , we have the following system of linear equation :
![x+y=200--------(i)\\\\x-20=7y-----------(ii)](https://tex.z-dn.net/?f=x%2By%3D200--------%28i%29%5C%5C%5C%5Cx-20%3D7y-----------%28ii%29)
We can write (ii) as :
![x-7y=20---(iii)](https://tex.z-dn.net/?f=x-7y%3D20---%28iii%29)
Subtract equation (iii) from (i) , we get
![8y=180\\\\ y=\dfrac{180}{8}=22.5](https://tex.z-dn.net/?f=8y%3D180%5C%5C%5C%5C%20y%3D%5Cdfrac%7B180%7D%7B8%7D%3D22.5)
Put this value in (1) , we get
![x+22.5=200\Rightarrow\ x=200-22.5=177.5](https://tex.z-dn.net/?f=x%2B22.5%3D200%5CRightarrow%5C%20x%3D200-22.5%3D177.5)
Hence , Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
