Solve the equation:
-2.6 + x = -4.6

• x = 2

• x = -2

• x = 7.2

• x = -7.2

Solve the equation -3x - 4.2 = 5.1

Use the inverse operations on both sides to identify what x is equal to.

Mrs. Magee's class is collecting books to donate to the local library. The class goal is to collect 60 books for the youth section, and Mrs. Magee's students have donated 15 books already. They plan to donate 3 more books every week until they reach their goal.
Which of the following could be used to determine w, the number of additional weeks that Mrs. Magee's class collects books?

• 15w + 3 = 60

• 15w - 3 = 60

• 3w - 15 = 60

• 3w + 15 = 60

The Carter family spends a total of $2,700 for a ski vacation in Colorado.  After spending $275 per day, they have $1,000 remaining.  About how many days, ne, has the Carter family already been on vacation?

• 275n - 1,000 = 2,700

• 275 + 1,000n = 2,700

• 275n + 1,000 = 2,700

• 1,000n - 275 = 2,700
