Calculating the Number of 2-Wheeled and 3-Wheeled Bicycles

To calculate the number of 2-wheeled and 3-wheeled bicycles among the 10 bicycles with 27 wheels in total, we can use the following approach:

Let's denote the number of 2-wheeled bicycles as x and the number of 3-wheeled bicycles as y. We know that the total number of bicycles is 10 and the total number of wheels is 27.

We can set up the following system of equations to represent this situation: 1. x + y = 10 (total number of bicycles) 2. 2x + 3y = 27 (total number of wheels)

Solving this system of equations will give us the values of x and y, representing the number of 2-wheeled and 3-wheeled bicycles, respectively.

Let's solve the system of equations to find the values of x and y.

Using the provided information, we can calculate the number of 2-wheeled and 3-wheeled bicycles as follows:

1. x + y = 10 2. 2x + 3y = 27

Solving the system of equations: - From equation 1, we can express x as x = 10 - y. - Substituting x into equation 2: 2(10 - y) + 3y = 27. - Simplifying the equation: 20 - 2y + 3y = 27. - Further simplification: 20 + y = 27. - Solving for y: y = 27 - 20 = 7. - Substituting y back into equation 1: x + 7 = 10. - Solving for x: x = 10 - 7 = 3.

Therefore, there are 3 2-wheeled bicycles and 7 3-wheeled bicycles among the 10 bicycles with 27 wheels in total.
