The school librarian, Mr. Marker, knows the library has 1,400 books but wants to reorganize how the books are displayed on the s

kipiarov [429]

Answer:

200 resource books

800 fiction books

400 nonfiction books

Step-by-step explanation:

Let's define x as the amount of resource books that are in the library. As he has four times as many fiction books as resource books, that means he has 4*x fiction books.

We also know he has half as many nonfiction books as fiction books, that is 1/2*4*x = 2*x nonfiction books.

We just need to find out the value of x.

We know there are 1,400 books in total and there are just 3 types of books. Therefore, if we sum all of them, we get the 1,400.

Written in math language, that is

x + 4x + 2x = 1,400

7x = 1,400

We divide by 7 on both sides and we get

7/7x = 1,400/7

x = 200

Now we replace the x with 200 to know how many books he has of each type:

Resource books = x = 200

Fiction books = 4*x = 4*200 = 800

Nonfiction books = 2*x = 2*200 = 400

Therefore, there are 200 resource books, 800 fiction books and 400 nonfiction books in the library.

Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution

bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

$2x - \frac{y}{2} = -8$

Required

Determine if $(3,28)$ is a solution

$(3,28)$ implies that:

$x = 3$

$y = 28$

To check if it is a solution, we simply substitute values for x and y in the given equation;

$2x - \frac{y}{2} = -8$

$2(3) - \frac{28}{2} = -8$

$6 - 14= -8$

$-8= -8$

Since both sides of the equation are equal; then, Yes, it is a solution
