Algebra.Com's Answer #723238 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! Total votes cast=x \n" ); document.write( "A-B=(1/8)x \n" ); document.write( "B-C=(1/7)x \n" ); document.write( "A=3C-350 \n" ); document.write( "A+B+C=x \n" ); document.write( "A=B +(1/8)x from the first \n" ); document.write( "B+(1/8)x+B+C=x \n" ); document.write( "2B+C=(7/8)x \n" ); document.write( "B-C=(1/7)x from the second \n" ); document.write( "3B=(57/56)x using common denominator of 56 \n" ); document.write( "B=(19/56)x \n" ); document.write( "Then C=(11/56)x substituting into B-C=(1/7)x \n" ); document.write( "A=(26/56)x \n" ); document.write( "Those three =x \n" ); document.write( "A=3C-350, so (26/56)x=(33/56)x-350, and -(7/56)x=-350=(-1/8)x, so that x=2800 votes \n" ); document.write( "A got 26/56 of them or 1300 \n" ); document.write( "B got 19/56 of them or 950 \n" ); document.write( "C got 11/56 of them or 550 \n" ); document.write( "ANSWER \n" ); document.write( " \n" ); document.write( " |
