write an INEQUALITY and solve each word problem:
\n" ); document.write( "
\r\n" );
document.write( "1. Ten less than a number is at most six. Find the number.\r\n" );
document.write( "\r\n" );
document.write( "To express \"ten less than a number\", think of starting with x and subtracting\r\n" );
document.write( "10.  So to express \"ten less than a number\" is to write x-10.\r\n" );
document.write( "\r\n" );
document.write( "To express \"is at most six\", think of \"equal 6 or less than 6\" or <.\r\n" );
document.write( "\r\n" );
document.write( "Inequality:             x-10 <  6 \r\n" );
document.write( "Add 10 to both sides:    +10  +10\r\n" );
document.write( "----------------------------------------\r\n" );
document.write( "                        x    < 16\r\n" );
document.write( "\r\n" );
document.write( "

\n" ); document.write( "2. Penny made a 74% on her first test. What must she get on her next test to have an average of at least 80% (100 points per test)?
\n" ); document.write( "
\r\n" );
document.write( "AVERAGE = (FIRST TEST + SECOND TEST)รท2 > 80%\r\n" );
document.write( "                           (74% + X)/2 > 80%\r\n" );
document.write( "Multiply thru by 2:            74% + X > 160%\r\n" );
document.write( "Subtract 74% from both sides  -74%       -74%\r\n" );
document.write( "---------------------------------------------------\r\n" );
document.write( "                                     X >  86%\r\n" );
document.write( "\r\n" );
document.write( "        \r\n" );
