Let \"+k+\" = constant of proportionality
\n" ); document.write( "\"+10+=+k%2A%28+1%2F2+%29+\"
\n" ); document.write( "\"+k+=+20+\"
\n" ); document.write( "----------------
\n" ); document.write( "Let \"+x+\" = attached weight
\n" ); document.write( "\"+18+=+k%2A%28+1%2Fx+%29+\"
\n" ); document.write( "\"+18+=+20%2A%28+1%2Fx+%29+\"
\n" ); document.write( "\"+18x+=+20+\"
\n" ); document.write( "\"+x+=+10%2F9+\"
\n" ); document.write( "\"+x+=+1.1+\" g ( rounded to nearest tenth )\r
