Miles read 4 books in the first half of March. By the end of March, the library had added Miles to the top-readers board for reading more than 10 books in a month. Let x represent how many books Miles read in the second half of March. Which inequality describes the problem?

Here, denotes number of books read by Miles in the second half of March

Step-by-step explanation:

Given: Miles read 4 books in the first half of March.

Also, Miles read more than 10 books in a month.

denotes number of books read by Miles in the second half of March.

To find: inequality that describes the problem.

Solution:

Total number of books read in month of March = Number of books read by Miles in the first half of March + Number of books read by Miles in the second half of March =  

Also, Miles read more than 10 books in a month.

Therefore,

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
