You can put this solution on YOUR website!
the equation is d(s) = 30 + 5*sqrt(s).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you are given that d(s) = 58.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the equation becomes 58 = 30 + 5 * sqrt(s).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 30 from both sides of the equation to get 28 = 5 * sqrt(s).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divide both sides of the equation by 5 rto get 28/5 = sqrt(s).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "square both sides of the equation to get (28/5)^2 = s.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for s to get s = 31.36.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "replace s in the original equation to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "58 = 30 + 5 * sqrt(31.36)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "evalute the equation to get 58 = 58.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this confirms the solution is correct.\r
