Solving and Writing One Step Equations and Inequalities

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

• q≤46
• q<46
• q≥46
• q<46

8x < 48

• x < -6

• x > -6

• x < 6

• x > 6

Four times a number increased by  7 is at least 19. 

• 4x > 19

• 4x + 7 ≥ 19

• 4x < 19

• 4x + 7 ≤ 19

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

y - 13 ≤ 15

• y ≤ 2

• y ≤ -2

• y ≤ 26

• y ≤ 28

x + 5 > 7

• x > -2

• x > 2

• x > 12

• x > -12

Solve x + 5 = 15
