If that doesn't make sense, my problem is that I don't know how to take an equation from a word problem. The problem is \"In a school zone, cars can go no more than 20 mi/h.\" I think I'm supposed to put x>=20, x meaning cars. That is suppose to mean cars can go less than or equal to twenty. Also I know the > Should have a line under it to show equal to, but I'm not sure how to show that on a computer.

You can put this solution on YOUR website!
In a school zone, cars cannot go more than 20 miles per hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you let x = the speed that the cars are allowed to go, then your equation becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x <= 20 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This means that x is smaller than or equal to 20 which means that the speed of the cars cannot exceed 20 miles per hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The common conventions are:\r
\n" ); document.write( "\n" ); document.write( "le means less than or equal to
\n" ); document.write( "ge means greater than or equal to
\n" ); document.write( "gt means greater than
\n" ); document.write( "lt means less than
\n" ); document.write( "eq means equals\r
