Algebra.Com's Answer #673495 by KMST(5328)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( " \n" ); document.write( "In 4 years, Cora's age will be \n" ); document.write( "and Rose's age will be \n" ); document.write( "The problem says that will be \n" ); document.write( "9 more than half Cora's age, \n" ); document.write( "which would be \n" ); document.write( " \n" ); document.write( "So,our equation is \n" ); document.write( " \n" ); document.write( "There are many different paths to the solution. \n" ); document.write( "Solve that equation whatever way feels comfortable to you. \n" ); document.write( "This is how I would \"show my work.\" \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Cora is \n" ); document.write( "and Rose is \n" ); document.write( " \n" ); document.write( "Checking: In 4 years, Cora will be 6 and Rose will be 12. \n" ); document.write( "Half of Cora's age will be 3, and 9 more than that will be 12. \n" ); document.write( " \n" ); document.write( "Explanation for my equation solving steps: \n" ); document.write( "To \"eliminate denominators\" I multiplied both sides of the equal sign times the 2 that appeared in the denominator. \n" ); document.write( "In baby steps, that would take me \n" ); document.write( "from \n" ); document.write( "Applying the distributive property, that is \n" ); document.write( " \n" ); document.write( "Then,I simplify that to \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "I do not write all those baby steps, \n" ); document.write( "I just do them in my head. \n" ); document.write( "In the next step, \n" ); document.write( "I add \n" ); document.write( "or subtract x and 20 from both sides of the equation, \n" ); document.write( "to have all the x's on one side and a'll the numbers without x's on the other. \n" ); document.write( "I could have done that in two steps \n" ); document.write( "if I had a teacher who liked it better that way. \n" ); document.write( " |
