Question

Lily is saving up to buy a cellphone. She needs to save at least $300 before she is able to buy the phone. Her grandfather gives her $40, and she earns $65 tutoring after school each week. Write an inequality for the number of weeks Lily will need to save to have at least $300, and describe the solutions.(2 points) x+ ≥, where x is the number of weeks Lily will need to save. Lily must save for at least weeks to have at least $300. HELP ME BOT

Answer 1

what number is that x??

Answer 2

Solve this problem by writing and solving an inequality. Five more than four times a number is less than 25. What are the possible values of the number? Show your work. (4 points)

Answer 3

The correct inequality is x * 65 + 40 ≥ 300, where x is the number of weeks Lily will need to save.

To solve this inequality, we first subtract 40 from both sides:

x * 65 ≥ 260

Then, we divide by 65 on both sides to find the value of x:

x ≥ 4

Therefore, Lily must save for at least 4 weeks to have at least $300.

Answer 4

In this case, x represents the number of weeks Lily will need to save in order to have at least $300. Since we found that x ≥ 4, it means that Lily must save for at least 4 weeks in order to have $300 or more saved up to buy the cellphone. So, in this context, x = 4 weeks.

Answer 5

Let's denote the number as "x".

The inequality based on the given information is:

4x + 5 < 25

Now, we can solve for x:

Subtract 5 from both sides of the inequality:

4x < 20

Divide by 4 on both sides:

x < 5

Therefore, the possible values of the number are all real numbers less than 5.
