Question

Write the word as an inequality. Then solve the inequality. Three less than a number x is more than 15. An inequality that represents this word sentence is__. The solution is__.

Answer 1

The inequality x > 18 represents the word sentence 'Three less than a number x is more than 15.' The solution to this inequality is that x is any number greater than 18.

Step-by-step explanation:

Three less than a number x can be represented as x - 3. When this expression is more than 15, it can be written as:

x - 3 > 15

To solve this inequality, we need to isolate x. Adding 3 to both sides gives us:

x - 3 + 3 > 15 + 3

x > 18

So, the inequality that represents the word sentence is x > 18. The solution to this inequality is that x is any number greater than 18.
