let a = the longest side, b & c are other sides
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "One side of triangle is one-third the longest side.
\n" ); document.write( "b = \"1%2F3\"a
\n" ); document.write( " The third side is 7 feet less than the longest side.
\n" ); document.write( "c = a - 7
\n" ); document.write( " The perimeter is 70.
\n" ); document.write( "a + b + c = 70
\n" ); document.write( "replace b with \"1%2F3\"a; replace c with (a-7)
\n" ); document.write( "a + \"1%2F3%7D%7D%5Da+%2B+%28a-7%29+=+70%0D%0A2%7B%7B%7B1%2F3\"a = 70 + 7
\n" ); document.write( "2\"1%2F3\"a = 77
\n" ); document.write( "Convert to an improper fraction
\n" ); document.write( "\"7%2F3\"a = 77
\n" ); document.write( "a = \"77%2F%287%2F3%29\"
\n" ); document.write( "a = \"77+%2A+3%2F7\"
\n" ); document.write( "Cancel the 7
\n" ); document.write( "a = 11 * 3
\n" ); document.write( "a = 33 ft is the longest side
\n" ); document.write( ":
\n" ); document.write( "I'll let you find b and c, see that they add up 70\r
