The pH level of a popular shampoo is between 6.0 and 6.5 inclusive.What compound inequality shows the pH levels of this shampoo?

6.0 <= pH <= 6.5

To form a compound inequality that represents the pH levels of the shampoo, you need to combine the individual inequalities for the lower and upper limits.

The given information states that the pH level is between 6.0 and 6.5 inclusive, which means it can be equal to 6.0 or 6.5 as well.

So the compound inequality for the pH level of the shampoo can be written as:

6.0 ≤ pH ≤ 6.5

In words, this compound inequality states that the pH level of the popular shampoo is greater than or equal to 6.0 and less than or equal to 6.5.

A compound inequality that shows the pH levels of the shampoo with a pH between 6.0 and 6.5 inclusive would be:

6.0 ≤ pH ≤ 6.5
