Answer:
D.) [tex]y=\frac{1}{7} g[/tex]
Step-by-step explanation:
Yellow parakeets = y
Green parakeets = g
Blue parakeets = b
There are 7 times as many yellow as green, which leaves us with the following equation:
[tex]7y = g[/tex]
We also know that there are 4 times as many green as blue - but this is just a distractor, this equation is irrelevant!:
[tex]4g =b[/tex]
The proper equation to solve for is [tex]7y=g[/tex]!
To solve, we do the following:
[tex]7y = g\\*\frac{1}{7}\\y = \frac{1}{7} g[/tex]
