Question

Solve the inequalityD/13≥ –3(A.) d ≥ –16(B.) d ≥ 39(C.) d ≥ 10(D.) d ≥ –39

Answer 1

The given inequality is:

$\begin{gathered} \frac{d}{13}\ge-3 \\ \text{Multiply both sides by 13} \\ \frac{d}{13}\cdot13\ge-3\cdot13 \\ \text{Simplify 13/13=1} \\ d\ge-39 \end{gathered}$

The answer is option D.
