Algebra.Com's Answer #625669 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Since y varies directly as z, we write that as \n" ); document.write( "y = kz \n" ); document.write( "Then we plug our data in to find k... \n" ); document.write( "46 = k(460) \n" ); document.write( "k = 46/460 = 1/10 \n" ); document.write( "so that \n" ); document.write( "y = (1/10)z \n" ); document.write( " |
