The library had 102 shelves of books. Each shelf had 14 books. Librarians checked out 807 books to students. how many books does the library have remaining?

627 Books

Let's go through this together.

First, let's figure out how many books are in the library in all

We'll multiply s times b

- S being the shelves

- B being the books per shelf.

102(14) = 1,428

So, there are 1,428 books in the library.

We also know that 801 of the 1,428 books were checked out.

Let's subtract the total number of books by the amount checked out.

1,428 - 801 = 627

Therefore, there are 627 books still in the library after checkout.  

the answer is ! ?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
