Algebra.Com's Answer #763971 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The variable z is directly proportional to x, and inversely proportional to y. When x is 14 and y is 19, z has the value 11.052631578947.\r \n" ); document.write( "\n" ); document.write( "What is the value of z when x= 19, and y= 24 \n" ); document.write( "------------------ \n" ); document.write( "11.052631578947 = 210/19 \n" ); document.write( "---- \n" ); document.write( "z = k*x/y where k is some constant. \n" ); document.write( "210/19 = k*14/19 \n" ); document.write( "k = 15 \n" ); document.write( "===================== \n" ); document.write( "What is the value of z when x= 19, and y= 24? \n" ); document.write( "z = 15*19/24 \n" ); document.write( "z = 95/8 \n" ); document.write( "---------------------------------- \n" ); document.write( "You can do it without finding the value of k, but the answer is the same. \n" ); document.write( " \n" ); document.write( " |
