Algebra.Com's Answer #192878 by Stitch(470)![]() ![]() ![]() You can put this solution on YOUR website! Setup: \n" ); document.write( "--------- \n" ); document.write( "Notice that each length is given in respect to the shotest piece. \n" ); document.write( "Let A = the length of the shortest piece \n" ); document.write( "Let B = the length of the second piece \n" ); document.write( "Let C = the length of the third piece \n" ); document.write( "Equation 1: \n" ); document.write( "Equation 2: \n" ); document.write( "Equation 3: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solution: \n" ); document.write( "--------------- \n" ); document.write( "Since we know what B and C equal in terms of A, we can substitute the values into equation 3 \n" ); document.write( "Equation 3: \n" ); document.write( " \n" ); document.write( "Combine like terms \n" ); document.write( " \n" ); document.write( "Add 2 to both sides \n" ); document.write( " \n" ); document.write( "Divide both sides by 4 \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now we can find the other lengths by replacing A with 24 in equations 1 & 2 \n" ); document.write( "Equation 1: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Equation 2: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Check the answers: \n" ); document.write( "------------------ \n" ); document.write( "We can check the answers by placing them back into eqaution 3 \n" ); document.write( "Equation 3: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
