Just do a single sprintf() call to put both the values into a single string, then send it.

sprintf( string_buffer, "ADC : %.2f V; Temp : %.2f C", voltage_value, temp );

As already noted, maximum string length is 20 characters.

BTW: what was with all that casting?!

Sure is possible. Co-join those two strings into one and send that. Be aware the new string needs to have a length of 20 bytes or less in total, so you may have to shorten some of your text around the values.
