A series of multiplying and adding all the bird feeder quantities
2(4.5)+2(2.75)= (9)+(5.5)=14.5 cups add the remaining bird seed of 3.5
14.5 +3.5= 18 cups at the beginning
-5, 50
Explaination: that is the point they connect.
The constant is 200.
Further explanation:
An inverse propertion states that if one quantity increases the other decreases and vice versa.
It can also be written as:
if y varies inversely with x
then
y∝1/x
y=k/x
When the proportionality symbol is removed, a proportionality constant is introduced
Given
y=40
x=5
Putting in equation
![40=\frac{k}{5}\\k=40*5\\k=200](https://tex.z-dn.net/?f=40%3D%5Cfrac%7Bk%7D%7B5%7D%5C%5Ck%3D40%2A5%5C%5Ck%3D200)
The constant is 200.

♥ Let's start off with the formula to solve:
![\frac{1}{2} a - \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20a%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Now solve that:
![\frac{1}{2} a-1](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20a-1)
Final asnwer:
![\frac{1}{2} a-1](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20a-1)
