Answer:
a < -11 (picture included)
Explanation:
To solve an inequality, you work it like a regular equation, with a few exceptions, such as flipping the inequality sign when you multiple or divide a number by a negative. Let's solve.
-6a > 66
Divide both sides by -6 and flip the inequality sign because we divided by a negative number.
a < -11
On a number line, it should look like the picture. It has an open hole because the inequality sign does not have a line under it.
