Answer:

The answer is D. p = 3.99b; $51.87.

Step-by-step explanation:

In this case first we have to represent the equation and then find the total price of the books in order to find the correct answer. This is:

Total price = p

Number of books = b

Cost of each book = $3.99

This is a case of multiplication were we have to multiply the number of books by the cost of each one to find the total price, this is:

$p=3.99*b$

Having this we can calculate the total price of buying 13 books, this is:

$p=3.99*13=51.87$

The total price of buying 13 books at $3.99 is $51.87.

The answer is D. p = 3.99b; $51.87.

What is the x-coordinate of the solution of the following system of equations?

Varvara68 [4.7K]

The easiest way to solve this is by elimination.

3x - y = 6

6x + y = 21

Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:

9x = 27

Then solving for x leaves you with x = 3

Then you take the x value of three and plug it into to either of the equations, so

3(3) - y = 6

9 - y = 6

subtracting 9

-y = -3

then dividing by -1

y = 3

so the solution is x = 3 y = 3 or (3,3)
