To win a game, you need at least 45 points. Each question is worth 3 points. Write and solve an inequality that represents the number of questions you need to answer correctly to win the game.

Verified Answer :

3x=45
(divide each side by 3)
x=15
You need to answer 15 correctly.

Answer:

\(3x\geq 45\); At-least 15 questions.

Step-by-step explanation:

Let x represent the number of questions you need to answer correctly..

We have been given that each question is worth 3 points. The points earned from answering x right questions would be \(3x\).

Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:

\(3x\geq 45\)

\(\frac{3x}{3}\geq \frac{45}{3}\)

\(x\geq 15\)

Therefore, you need to answer at-least 15 questions correctly to win the game.
