Algebra.Com's Answer #221785 by Alan3354(69443) You can put this solution on YOUR website! THE UNITS DIGIT OF A TWO DIGIT NUMBER IS THREE TIMES THE TENS DIGIT. IF THE DIGITS ARE REVERSED THE RESULTING NUMBER IS 36 MORE THAN THE ORIGINAL NUMBER. WHAT IS THE ORIGINAL NUMBER? \n" ); document.write( "--------------------- \n" ); document.write( "The difference from reversing digits is 9 times the difference between the 2 digits. \n" ); document.write( "A difference of 36 means the 10s and 1s digits differ by 4. \n" ); document.write( "---------------------------- \n" ); document.write( "Only A has a difference between them of 4. \n" ); document.write( "--------------- \n" ); document.write( "62 - 26 = 36 \n" ); document.write( "And, 6 is 3x 2, so that's the answer. \n" ); document.write( "You're right, the answer is obviously A. \n" ); document.write( " \n" ); document.write( " |
