You surveyed 30 students to see how many CDs they owned.
The number of students who owned 5 - 8 CDs was:
= 15
The number of students who owned 9 - 12 CDs was:
= 10
The number of students who owned 13 - 16 CDs was:
= 5
The number of students who owned 17 - 20 CDs was:
= 0
The total number of students surveyed is the sum of the above:
= 15 + 10 + 5 + 0
= 30 students
30 students were surveyed for this study.

[ Answer ]
![\boxed{Width \ = \ 31\frac{19}{91} \ Ft^{2}}](https://tex.z-dn.net/?f=%5Cboxed%7BWidth%20%5C%20%3D%20%5C%2031%5Cfrac%7B19%7D%7B91%7D%20%5C%20Ft%5E%7B2%7D%7D)
[ Explanation ]
Area = 1420
Width = ![45\frac{1}{2}](https://tex.z-dn.net/?f=45%5Cfrac%7B1%7D%7B2%7D)
Area For Rectangle: Length · Width
Use division to find width:
1420 ÷ ![45\frac{1}{2}](https://tex.z-dn.net/?f=45%5Cfrac%7B1%7D%7B2%7D)
Convert mixed numbers to fractions:
1420 = ![\frac{1420}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1420%7D%7B1%7D)
= ![\frac{91}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B2%7D)
÷ ![\frac{91}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B2%7D)
Use mixed multiplication:
![\frac{1420*2}{1*91}](https://tex.z-dn.net/?f=%5Cfrac%7B1420%2A2%7D%7B1%2A91%7D)
= ![\frac{2140}{91}](https://tex.z-dn.net/?f=%5Cfrac%7B2140%7D%7B91%7D)
Simplify:
= ![31\frac{19}{91}](https://tex.z-dn.net/?f=31%5Cfrac%7B19%7D%7B91%7D)
![\boxed{[ \ Eclipsed \ ]}](https://tex.z-dn.net/?f=%5Cboxed%7B%5B%20%5C%20Eclipsed%20%5C%20%5D%7D)
Answer:
![m = \frac{k + 2}{3}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bk%20%2B%202%7D%7B3%7D)
Step-by-step explanation:
![k = 3m - 2 \\ 3m = k + 2 \\ m = \frac{k + 2}{3}](https://tex.z-dn.net/?f=k%20%3D%203m%20-%202%20%5C%5C%203m%20%3D%20k%20%2B%202%20%5C%5C%20m%20%3D%20%20%5Cfrac%7Bk%20%2B%202%7D%7B3%7D%20)
