Algebra.Com's Answer #100339 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! luis chooses a number between 1 and 200. if he divides his number by 10, the remainder is 9. if he divides his number by 8 the remainder is 7 and if he divides his number by 6 the remainder is 5. what is the number luis chose? \n" ); document.write( "--------------- \n" ); document.write( "Let the number be y where 1 \n" ); document.write( "EQUATIONS: \n" ); document.write( "y = 10m + 9 where m is an integer. \n" ); document.write( "y = 8n + 7 where n is an integer \n" ); document.write( "-------------------- \n" ); document.write( "10m+9 = 8n+7 \n" ); document.write( "10m-8n = -2 \n" ); document.write( "--------------- \n" ); document.write( "Examine integral multiples of 10 and integral multiples of 8 \n" ); document.write( "till you find a difference of -2. \n" ); document.write( "----------- \n" ); document.write( "10m = 30 8n=32 \n" ); document.write( "m=3 nd n=4 \n" ); document.write( "----------------- \n" ); document.write( "Therefore y = 10m+9 = 10*3 +9 = 39 \n" ); document.write( "Checking: y = 8n+7 = 8*4 + 7 = 39 \n" ); document.write( "========================= \n" ); document.write( "Luis chose the number 39 \n" ); document.write( "=============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. |
