Translate the following statements into inequalities.
\n" ); document.write( "and use x to represent the number
\n" ); document.write( "1. 2 times a number, increased by 28, is less than or equal to 6 times that number.
\n" ); document.write( "Do it like this:
\n" ); document.write( "\" 2 times a number\"; 2x
\n" ); document.write( "\"increased by 28\": 2x + 28
\n" ); document.write( "\"is less than or equal to 6 time that number\": = <= 6x
\n" ); document.write( "We have:
\n" ); document.write( "2x + 28 <= 6x
\n" ); document.write( ":

\n" ); document.write( "2.Sam must have an average of 70 or more in his summer course to obtain a grade of C. His first three test grades were 75, 63, and 68. Write an inequality representing the score that Sam must get on the last test to get a C grade.
\n" ); document.write( ":
\n" ); document.write( "Let the 4th grade which is unknown = x: Write an average equation:
\n" ); document.write( "\"%28%2875+%2B+63+%2B+68+%2B+x%29%29%2F4\" => 70
\n" ); document.write( ":
\n" ); document.write( "\"%28%28x+%2B+206%29%29%2F4\" => 70
\n" ); document.write( ":
\n" ); document.write( "Simplify, get rid of the denominator, mult both sides by 4
\n" ); document.write( "x + 206 => 4(70)
\n" ); document.write( "x + 206 => 280
\n" ); document.write( "x => 280 - 206
\n" ); document.write( "x => 74
