Question

What is the solution to the inequality?

1.5−2.5x≤4.5

Answer 1

Answer:

x ∈ [-1.2, ∞)

Step-by-step explanation:

1.5− 2.5x ≤ 4.5

15 - 25x ≤ 45

-25x ≤ 45 - 15

-25x ≤ 30

When a negative number goes on other side in division and multiply form it changes the sign.

if the sign is greater than it changes into lesser than and vice versa

x ≥ 30/-25

x ≥ -6/5

x ≥ -1.2

x ∈ [-1.2, ∞)
