Question

Which work correctly uses properties of inequality to find the solution to –0.4x – 10 > 14?

Answer 1

Answer:

x < -60

Step-by-step explanation:

Our inequality is:

-0.4x - 10 > 14

Add 10 to both sides:

-0.4x > 14 + 10

-0.4x > 24

Divide both sides by -0.4; remember that when dividing an inequality by a negative number, we must flip the inequality:

x < 24/-0.4

x < -60

Hope this helps!

Answer 2

Answer:

x ∈ (-oo ; - 60)

Step-by-step explanation:

–0.4x – 10 > 14

- 10 - 14 > 0.4x

- 24 > 0.4x

x < - 60

x ∈ (-oo ; - 60)
