Algebra.Com's Answer #51545 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The numbers A and B each have 3 digits. Zoe was asked to calculate AxB. Instead she put A on the left of B to form 6 digit numbers, D. Her answer was 3 times the correct answer. What is A and B? \n" ); document.write( ": \n" ); document.write( "For what it's worth, (not much you will probably say) \n" ); document.write( "I can show you how to solve it using a graphing calc like a Ti83 \n" ); document.write( ": \n" ); document.write( "The problems states: \n" ); document.write( "1000A + B = 3(AB) \n" ); document.write( ": \n" ); document.write( "B - 3AB = - 1000A \n" ); document.write( "B(1-3A) = - 1000A \n" ); document.write( "B = -1000A/(1-3A) \n" ); document.write( ": \n" ); document.write( "enter into calc: y = -1000x/(1-3x): use the x,y table \n" ); document.write( "The first integers that satisfy the requirements are: \n" ); document.write( "A = 167, B= 334 \n" ); document.write( "3(167*334) = 167334\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
