Question 1045749
Let {{{ V }}} = the voltage of the 2nd battery
{{{ 2V }}} = the voltage of the 1st battery
Let {{{ V[3] }}} = the voltage of the 3rd battery
{{{ 2V = (1/3)*V[3] }}}
{{{ V[3] = 6V }}}
------------------
{{{ 2V + V + 6V = 54 }}}
{{{ 9V = 54 }}}
{{{ V = 6 }}}
and
{{{ 2V = 12 }}}
{{{ 6V = 36 }}}
---------------
The battey voltages are:
12V , 6V , 36V
----------------
check answer:
{{{ 2V + V + 6V = 54 }}}
{{{ 12 + 6 + 36 = 54 }}}
{{{ 54 = 54 }}}
OK
