Ashelf is 24 inches wide. how many books, each 7/8 of an inch thick, can fit on the shelf?

A.

Step-by-step explanation:

You have to divide the total shelf by the size of the books. In other words, you are finding how many books can go on/into the shelf.  This fits the definition of division relatively well. Have a great morning/afternoon/night, hope this helped! :0)

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
