Answer:
skis and snowboards were rented.
Step-by-step explanation:
Let the number of skis rented be and the number of snowboards rented be .
If a total of people rented on a certain day, then the total number of skis and snowboards rented that particular day is also .
This gives us the equation
.
If skis cost $ , then number of skis cost $ .
If snowboards cost $ , then number of snowboards cost $ .
The total cost will give us another equation,
From equation (1),
.
We put equation (3) into equation (2) to get,
We expand the brackets to obtain,
We group like terms to get,
This implies that,
We divide both sides by to get,
We put into equation (3) to get,
Therefore skis and snowboards were rented.
To solve this problem, you can set up a system of equations where one equation represents the total number of skis and snowboards rented, and the other represents the total cost of those rentals. By solving this system, you can determine the number of skis and snowboards rented.
This problem is a classic example of a system of linear equations. Let's denote the number of skis rented as x and the number of snowboards rented as y. From the problem, we know that:
By solving these two equations, we can find the values of x and y which represent the number of skis and snowboards rented respectively.

Two lines, A and B, are represented by equations given below:
Line A: y = x - 4
Line B: y = 3x + 4
Which of the following shows the solution to the system of equations and explains why?
0 (-3,-5), because the point satisfies one of the equations
0 (-3,-5), because the point lies between the two axes
(-4,-8), because the point satisfies both equations
(-4, -8), because the point does not lie on any axis
Given:
The system of equations is:
Line A:
Line B:
To find:
The solution of given system of equations.
Solution:
We have,
...(i)
...(ii)
Equating (i) and (ii), we get
Divide both sides by 2.
Substituting in (i), we get
The solution of system of equations is (-4,-8).
Now verify the solution by substituting in the given equations.
This statement is true.
Similarly,
This statement is also true.
Therefore, (-4,-8) is a solution of the given system of equations, because the point satisfies both equations. Hence, the correct option is C.
