Use technology to solve the system of equations. Express all solutions as decimals, rounded to one decimal place.
$\begin{array} { l }
1.6 x + 2.4 y - 3.2 z = 17.6 \
5.1 x - 6.3 y + 0.6 z = - 12.8 \
4.2 x + 3.5 y + 4.9 z = 40.4
\end{array}$
A) $( 3.2,11.0 , - 0.7 )$
B) $( 5.2,5.5 , - 0.7 )$
C) $( 5.2,11.0 , - 0.7 )$
D) $( 5.2,5.5,0.7 )$
E) $( 4.2,5.5,0.7 )$
