Algebra.Com's Answer #588168 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! let a = the hundreds digit \n" ); document.write( "let b = the tens \n" ); document.write( "let c = the units \n" ); document.write( "In a 3 digit number, unit digit is more than the hundred digit, \n" ); document.write( "c > a \n" ); document.write( ": \n" ); document.write( " are in a ratio 1:2:3; therefore: \n" ); document.write( "b = 2a \n" ); document.write( "c = 3a \n" ); document.write( ": \n" ); document.write( "if the diff of original number and the number obtained by reversing the digit is 594, \n" ); document.write( "Reverse number - original number 594 \n" ); document.write( "(100c + 10b + a) - (100a + 10b + c) = 594 \n" ); document.write( "100c + 10b + a - 100a - 10b - c = 594 \n" ); document.write( "Combine like terms \n" ); document.write( "99c - 99a = 594 \n" ); document.write( "simplify, divide by 99 \n" ); document.write( "c - a = 6 \n" ); document.write( "we know c = 3a \n" ); document.write( "3a - a = 6 \n" ); document.write( "2a = 6 \n" ); document.write( "a = 3 \n" ); document.write( "then \n" ); document.write( "b = 2(3) = 6 \n" ); document.write( "c = 3(30 = 9 \n" ); document.write( ": \n" ); document.write( " find the number: 369 is the original number \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "See if that checks out \n" ); document.write( "963 - 369 = 594 \n" ); document.write( " |
