Juana, Anish, and Giselle are comparing their solutions to the inequality 5/6x≤−10 . Juana says that the inequality symbol must be reversed because there is a negative sign in the inequality. Anish says the Multiplication Property of Inequality or Division Property of Inequality must be applied. Giselle says the inequality symbol must stay the same.

Answer 1

To solve the inequality \( \frac{5}{6} x \leq -10 \), we need to isolate \( x \).

First, we can multiply both sides of the inequality by \( \frac{6}{5} \) in order to eliminate the fraction. However, we must be careful:

1. Multiplication by a Positive Number: Since \( \frac{6}{5} \) is positive, the inequality symbol will not change.
2. Applying the Multiplication: We multiply both sides: \[ x \leq -10 \cdot \frac{6}{5} \] \[ x \leq -12 \]

Now, let's analyze the statements of Juana, Anish, and Giselle:

• Juana: She incorrectly states that the inequality symbol must be reversed because there is a negative sign in the inequality. This is not true; we only reverse the inequality when we multiply or divide by a negative number.

• Anish: He correctly states that we must apply the Multiplication Property of Inequality (by multiplying both sides by \(\frac{6}{5}\)). So he is correct.

• Giselle: She says the inequality symbol must stay the same, which is correct only under the premise that we are multiplying by a positive number. Since we did not multiply or divide by any negative number, this statement is accurate.

Therefore, the correct combination of people is:

Giselle and Anish.
