Quadrent 1 because they are both positive numbers
The unknown is the distance in kilometres
The given is the distance in miles=140 miles
1 mile=1.6093km

Therefore the 140 miles in km is 225.302km
A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.
Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.
Answer:
the first option - 48s + 4.75
Step-by-step explanation:
Six books at 8 dollars each is equivalent to $48.00
You are only paying 80% of that cost (100%-20%)
Therefore you are multiplying 48 by .8
Your answer should be equal to $38.40
