Faith mixes 14 liters of 12% acid solution with a 30% acid solution which results in an 18% acid solution. \n" ); document.write( "If x represents the number of liters of 30% acid solution used, which equation can be used to find the number of liters of 30% acid solution in the mixture?\r \n" ); document.write( "\n" ); document.write( ".30x+.12(14)=.18(14+x) \n" ); document.write( ".30x+1.68=2.52+.18x \n" ); document.write( ".30x-.18x=2.52-1.68 \n" ); document.write( " .12x=.84 \n" ); document.write( " x=7\r \n" ); document.write( "\n" ); document.write( "ans: the number of liters of 30% acid solution used in the mixture is 7 \n" ); document.write( " \n" ); document.write( " |
