(No links and no copying websites((Especially web 2.0 calc)) or you'll be reported If $a, b,c$ are positive integers less than $13$ such that\begin{align*}
2ab+bc+ca&\equiv 0\pmod{13}\\
ab+2bc+ca&\equiv 2abc\pmod{13}\\
ab+bc+2ca&\equiv 8abc\pmod {13}
\end{align*}then determine the remainder when $a+b+c$ is divided by $13$.
Thanks!

its not b

step-by-step explanation:

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05
