The compound inequality that gives the normal range for the pH values of lemon juice is given by:
<h3>What is a compound inequality?</h3>
A compound inequality is modeled by:
Which means that x is greater than a and less than b. In this problem, the pH is greater than 1.5 and less than 4, hence the inequality is given by:

Answer:
5 and 1 over 6
Step-by-step explanation:
<u>Simplifying the given:</u>
- Negative 2 and 1 over 6 – negative 7 and 1 over 3 ⇒ <em>translated as</em>:
- - 2 1/6 - (-7 1/3) = ⇒ <em>cancelling negatives and changing mixed fractions to improper fractions</em>
- - 13/6 + 22/3 = ⇒ <em>bringing to same denominator</em>
- - 13/6 + 44/6 = ⇒ calculating the numerator
- 31/6 = ⇒ making mixed fraction
- 5 1/6 ⇒ answer
<u>Correct choice is the last one: </u>5 and 1 over 6
