Question

I don't understand this plz help

Answer 1

option 4

Explanation:

Solving the inequality

4.5 + 1.2x ≥ 10 - x ( add x to both sides )

4.5 + 2.2x ≥ 10 ( subtract 4.5 from both sides )

2.2x ≥ 5.5 ( divide both sides by 2.2 )

x ≥ 2.5

3, 4, 5, 6 are all greater than 2.5, thus

All values in the set make the inequality true
