10x + 9 = 4x - 9

-3

-18

13.

What is the first step you should take to solve this problem?

WRITE AN EQUATION TO REPRESENT THE SITUATION

Celebrity A has 400 followers on social media and is gaining 75 followers each day. Celebrity B has 1,000 followers on social media, but is losing 25 followers a day.

400 - 75x = 1,000 + 25x

400 + 75x = 1,000 – 25x

400x - 75 = 1,000x + 25

400x + 75 = 1,000x – 25

15.

WRITE AN EQUATION TO REPRESENT THE SITUATION

Shelby has $155 in savings, and her boyfriend George has $230. Shelby is saving $10 each week, and George is spending $15 each week.

155x - 10 = 230x + 15

155x + 10 = 230x – 15

155 - 10x = 230 + 15x

155 + 10x = 230 – 15x

16.

The Rug store installs carpet for $80 plus $9.50 per square yard of carpet. The Magic Carpet charges $120 for installation and $7.50 per square yard of carpet. Write an inequality that could be used to determine the number of square yards of carpet that need to be installed for The Rug Store to charge more than The Magic Carpet.

80+9.50x > 120+7.50x

80+9.50x < 120+7.50x

80x+9.50 > 120x+7.50

80x+9.50 < 120x+7.50

17.

Cody’s Gym charges a $15 fee to join and $30 per month. Tyler’s Gym charges a $30 fee to join and $20 per month. Write an inequality that could be used to determine after how many months Tyler’s gym would be a better deal.

30 + 20x < 15 + 30x

30x + 20 < 15x + 30

30 + 20x > 15 + 30x

30x + 20 > 15x + 30
