Algebra.Com's Answer #14592 by bmauger(101)![]() ![]() ![]() You can put this solution on YOUR website! The three equations you should use are: \n" ); document.write( "A=5B (A is 5 times B) \n" ); document.write( "C=B-16 (C is 16 less than B) \n" ); document.write( "A+B+C=180 (Rule from geometry)\r \n" ); document.write( "\n" ); document.write( "Substitue for A & C in terms of B in the third equation to get: \n" ); document.write( " \n" ); document.write( "You should be fine from here. \n" ); document.write( " |
