Question

Tri scored a total of 31 points in the basketball game, and he scored p points in the second half of the game.Write an expression to determine the number of points he scored in the first half of the game. Then, find the number of points he scored in the first half of the game if he scored 7 points in the second half of the game.

Answer 1

Since he scored a total of 31 points in the game

Since he scored p points in the second half

Since the total points = first half + second half, then

First + p = 31

The number scored in the first half = 31 - p

The expression is,

The score of the first part = 31 - p

Since he scored 7 points in the second half

That means p = 7

Then his score in the first part = 31 - 7 = 24

He scored 24 points in the first half
