Step-by-step explanation:

\footnotesize\begin{aligned}\left(2a-\frac{1}{3}\right)\div\frac{b}{15}&=\left(2\left(\frac{-2}{5}\right)-\frac{1}{3}\right)\div\left(\frac{-8.25}{15}\right)\\&=\left(\frac{-4}{5}-\frac{1}{3}\right)\div \left(\frac{-825}{1,500}\right)\\&=\left(\frac{-12-5}{15}\right)\div\left(\frac{-11}{20}\right)\\&=\left(\frac{-17}{15}\right)\div\left(\frac{-11}{20}\right)\\&=\frac{17}{15}\times\frac{20}{11}\\&=\frac{340}{165}\\&=\frac{68}{33}\\&=2\frac{2}{33}\\&\approx\bf 2.06\end{aligned}

Answer:

B)  1 < x < 13

Step-by-step explanation:

use triangle inequality theorem which states that the sum of any two sides must be greater than the third side

let x = third side

6 + 7 > x;    x < 13

6 + x > 7;    x > 1

x + 7 > 6;   x > -1

there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
