Algebra.Com's Answer #746279 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "There are many different ways to solve this problem using formal algebra. All of them result in a quadratic equation that needs to be factored to solve the problem. \n" ); document.write( "One response you have received shows the work up to \"c(c-11)=180\" and then gives the (wrong) answers without showing how the equation was solved. \n" ); document.write( "A different formal algebraic solution I tried ends up with an uglier quadratic equation which is even harder to solve by factoring. \n" ); document.write( "But if a formal algebraic solution is not required, the original problem can be solved with logical trial and error, requiring mathematics that is far simpler than any algebraic solution. \n" ); document.write( "The original problem requires you to find two whole numbers whose product is 60, with one of the numbers being 11 more than 3 times the other. \n" ); document.write( "There aren't a lot of pairs of whole numbers whose product is 60; and the requirement that one of them be MUCH larger than the other leaves only a couple of possibilities to try: 2 and 30, or 3 and 20. \n" ); document.write( "The pair 3 and 20 satisfies the second requirement; it is the answer. \n" ); document.write( " |
