Answer:
80 parrots were purchased.
Step-by-step explanation:
Let the total number of parrots be k.
If 20% (or 20/100 = 1/5) flew away and 5% (5/100 = 1/20) died, the remaining parrots will be k – (¹/₅k + ¹/₂₀k) = k – ¼k = ¾k.
Of the remaining, 45% (or 45/100 = 9/20) were sold, which means the total number of sold parrots will be ¾k × ⁹/₂₀ = ²⁷/₈₀k.
The remaining parrots = ¾k – ²⁷/₈₀k = ³³/₈₀k = 33
k = 33 × ⁸⁰/₃₃ = 80 parrots were purchased.
The answer to the question is it would add twenty seven every two times it goes up
Answer:
−1/3y+−4/3
Step-by-step explanation:
We need to solve for x.
How? Easy! :D
Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:
−3x−4=y
Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:
−3x−4+4=y+4
−3x=y+4
Step three: Divide both sides by -3.
-3x/-3 = y+4/-3.
Step four: Wrap-up. What the answer is.
x = -1/3y + -4/3
Final step: OUR ANSWER!
x = -1/3 + -4/3
Hope this helped! :D
