# Classify the following math problem: -1/3t <= -5, t >=

Equation, expression, and inequalitie
Classify the following math problem: $$\displaystyle-\frac{{1}}{{3}}{t}\le-{5},{t}\ge{15}$$ are equivalent inequalities or not equivalent ones?
$$\displaystyle-\frac{{1}}{{3}}{t}\le-{5}$$
$$\displaystyle-\frac{{1}}{{3}}{t}\times{\left(-{3}\right)}\le-{5}\times{\left(-{3}\right)}$$
$$\displaystyle{t}\ge{15}$$, which means that inequalities are equivalent.
