Central High School plays Eastern High School in a basketball game. Eastern had double the score of Central before Central scored a three-pointer as the game ended.
The variable, c, represents Central's score before the three-pointer. Express the total points scored in the game as a variable expression. Check all that apply.
- 2c + c
- 2c + 3
- 3c + 3
- 2c + c – 3
- 2c – c + 3
- 2c + c + 3
Answer:
(C)3c + 3
(F)2c + c + 3
Step-by-step explanation:
- Central High School's Score = c
- Eastern had double the score of Central, therefore Eastern High School's Score =2c
- Central then scored a 3 pointer.
Therefore:
Total Points Scored in the game =c+2c+3 (This is option F)
Simplifying, we have:
c+2c+3=3c+3 (This is option C)
Therefore, C and F are the correct options.
