Question

A basketball player scored 33 points during a game by shooting 1-point free throws, 2-point field goals, and 3-point field goals. The player scored 17 times. She scored 3 more 2-point field goals than 1-point free throws. The system of equations below represents the situation, where x is the number of 1-point free throws, y is the number of 2-point field goals, and z is the number of 3-point field goals. x + y + z = 17 x + 2y + 3z = 33 y – x = 3

Answer 1

Answer:

The number of 1 point throw is 5, the number of 2 point throw is 8 and the number of 3 point throw is 4

Step-by-step explanation:

Let x represent the number of  1-point free throws, y is the number of 2-point field goals, and z is the number of 3-point field goals. A basketball player scored 33 points during a game by shooting 1-point free throws, 2-point field goals, and 3-point field goals. Each of 1 point free throw is 1 point, each of 2 point free throw is 2 points and each of the 3 point free throw is 3 points. This is represented by the equation:

x + 2y + 3z = 33             (1)

Also, The player scored 17 times, therefore it is represented by:

x + y + z = 17                   (2)

The player scored  3 more 2-point field goals than 1-point free throws, it is represented by:

y = x + 3                      

-x + y = 3                         (3)

Solving equation 1, eqn 2 and eqn 3 simultaneously:

x = 5, y = 8, z = 4.

The number of 1 point throw is 5, the number of 2 point throw is 8 and the number of 3 point throw is 4
