For this case, the first thing we must do is define variables.
We have then:
x: length of the bookshelf
y: thickness of each book
The equation for the number of books is:
Substituting values we have:
Doing the calculation we have:
Answer:
200 copies of this book will fit on the bookshelf
Step 1: 0.35 = 35⁄100
Step 2: Simplify 35⁄100 = 7⁄20
answer: 7/20
3x + 5y = 384x − 2y = 16x = −4, y = 6x = 4, y = 6x = 6, y = −4x = 6, y = 4
The XY is dilated by a scale factor of 1.3 with the origin as the center of dilation to create the X'Y'. So the length of X'Y' is 1.3 times of origin but the slope is the same. The slope is m
