Question

Given: x + 3.8 > -10.02. Choose the solution set. a. {x | x ∈ R, x > -6.22} b. {x | x ∈ R, x > -10.40} c. {x | x ∈ R, x > -13.82}

Answer 1

$x+3.8 \ \textgreater \ -10.02 \\ x\ \textgreater \ -10.02 - 3.8 \\ x\ \textgreater \ -13.82 \\ \\ \{ x | x \in \mathbb{R}, x\ \textgreater \ -13.82 \}$

The answer is C.
