Linear Inequality Skills

A number is at most 5. Write this as a linear inequality.

• x <= 5

• x > 5

• x < 5

• x = 5

Twice a number decreased by 7 is less than 15. Write this as a linear inequality.

• 2x - 7 > 15

• 2x - 7 = 15

• 2x - 7 < 0

• 2x - 7 < 15

The sum of a number and 8 is at least 20. Write this as a linear inequality.

• x + 8 >= 20

• x - 8 >= 20

• x + 8 <= 20

• x + 8 > 20

Three times a number is greater than or equal to 21. Write this as a linear inequality.

• 3x + 21

• 3x >= 21

• 3x = 21

• 3x > 21

The difference between a number and 4 is no more than 10. Write this as a linear inequality.

• |x - 4| = 10

• |x - 4| < 10

• |x - 4| > 10

• |x - 4| ≤ 10

Half of a number increased by 3 is greater than 9. Write this as a linear inequality.

• x > 12

• x > 9

• x = 12

• x < 12

The product of a number and 5 is less than 30. Write this as a linear inequality.

• 5x < 30

• x * 5 < 30

• x * 5 > 30

• 5x = 30

The quotient of a number and 2 is at least 7. Write this as a linear inequality.

• x <= 7

• x > 14

• x = 14

• x >= 14
