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
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.
what number is that x??
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.
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)
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.
