Let b be the initial amount of books. Steve sells half of his books, so the number of Steve's books become
![b \to \dfrac{b}{2}](https://tex.z-dn.net/?f=%20b%20%5Cto%20%5Cdfrac%7Bb%7D%7B2%7D%20)
Then, he buys 6 more, so the number increases by 6:
![\dfrac{b}{2} \to \dfrac{b}{2}+6](https://tex.z-dn.net/?f=%20%5Cdfrac%7Bb%7D%7B2%7D%20%5Cto%20%5Cdfrac%7Bb%7D%7B2%7D%2B6%20)
This number is now 14, so you have
![\dfrac{b}{2}+6 = 14](https://tex.z-dn.net/?f=%20%5Cdfrac%7Bb%7D%7B2%7D%2B6%20%3D%2014%20)
Subtract 6 from both sides:
![\dfrac{b}{2} = 8](https://tex.z-dn.net/?f=%20%5Cdfrac%7Bb%7D%7B2%7D%20%3D%208%20)
Multiply both sides by 2:
![b = 16](https://tex.z-dn.net/?f=%20b%20%3D%2016%20)
Answer:
Domain : ( -3 , 4.5 )
Step-by-step explanation:
Answer:
1/5 divided by 4 equals to 0.05
7/8*8/9 = (7*8)/(8*9)
Since we have an 8 both above and below, we can erase it, and so the answer is 7/9
