Math Problem Statement

A quantity t that is greater than -5 and less than 4. Select the correct inequality from the options.

Solution

The statement asks for an inequality describing a quantity tt that is greater than 5-5 and less than 4. This means we want to express the condition 5<t<4-5 < t < 4, which states that tt is between 5-5 and 4, not inclusive of the endpoints.

Looking at the answer choices:

  • A. 5<t>4-5 < t > 4: This is incorrect because it is not a valid mathematical expression. It tries to compare tt with two values incorrectly.
  • B. 5>t>4-5 > t > 4: This is incorrect because it implies tt is less than 5-5 and less than 4, which is not the desired condition.
  • C. 5t4-5 \leq t \leq 4: This is incorrect because it implies tt can be equal to 5-5 and 4, but the problem asks for tt to be strictly between them.
  • D. 5<t<4-5 < t < 4: This is correct. It matches the description perfectly.
  • E. 5t4-5 \leq t \geq 4: This is incorrect because it suggests tt could be equal to both 5-5 and greater than 4, which is not possible.

Therefore, the correct answer is D: 5<t<4-5 < t < 4.

Do you have any questions or need further explanation?

Here are 5 follow-up questions for practice:

  1. How would you write an inequality for a number xx that is greater than or equal to 2 but less than 8?
  2. What does it mean if an inequality uses \leq instead of <<?
  3. Can you graph the solution to the inequality 5<t<4-5 < t < 4?
  4. What is the difference between strict inequalities and non-strict inequalities?
  5. How would you solve an inequality like 3x+2>83x + 2 > 8?

Tip: When solving inequalities, always remember that flipping the inequality sign is necessary when multiplying or dividing by a negative number!
