If the average of 3,s, and t is 5, what is the value of s+t?
\n" ); document.write( "the equation for this:
\n" ); document.write( "\"%283+%2B+s+%2B+t%29%2F3\" = 5
\n" ); document.write( "multiply both sides by 3
\n" ); document.write( "3 + s + t = 15
\n" ); document.write( "s + t = 15 - 3
\n" ); document.write( "s+t = 12
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check
\n" ); document.write( "\"%283+%2B+12%29%2F3\" = 5
\n" ); document.write( "
\n" );
