Answer:
c 32 out of 80 were surveyed
Answer:
7a) y = ![\frac{1273x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1273x%7D%7B5%7D)
b) this equation means that for every 5 minutes the tram is an additional 1,273 feet above base
c) the first quadrant has 'x' and 'y' values that are positive and only positive values can be used to represent elevation above base and time

Answer:
![\frac{9}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B16%7D)
Step-by-step explanation:
Let total number of students![=x](https://tex.z-dn.net/?f=%3Dx)
Students went to the book fair:
Students went to book fair![=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x](https://tex.z-dn.net/?f=%3D%5Cfrac%7B15%7D%7B20%7D%5Ctimes%20total%5C%20number%5C%20of%5C%20students%3D%5Cfrac%7B15%7D%7B20%7Dx)
Students who bought book:
![Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x](https://tex.z-dn.net/?f=Students%5C%20who%5C%20bought%5C%20book%3D%5Cfrac%7B12%7D%7B16%7D%5Ctimes%20Number%5C%20of%5C%20students%5C%20went%5C%20to%5C%20book%5C%20fair%3D%5Cfrac%7B12%7D%7B16%7D%5Ctimes%20%5Cfrac%7B15%7D%7B20%7Dx%3D%5Cfrac%7B9%7D%7B16%7Dx)
Hence
of total students bought at least one book.
I think you mean simplify:
2x + 3 = x + x + 3.
We can start by moving all the variables to one side, and the numbers to another:
2x - x - x = 3 - 3.
0 = 0.
Sooo the answer is 0 I guess.
