document.write( "Question 890580: Two alloys A and B are composed of two basic elements. The ratios of the components of the two basic elements in the two alloys are 5:3 and 1:2 respectively. A new alloy X is formed by mixing the two alloys A and B in the ratio 4:3.What is the ratio of the compositions of the two basic elements in alloy X. \n" ); document.write( "
Algebra.Com's Answer #539093 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! Ratio of the two elements as x:y, assuming based on masses.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let p = how much of alloy A \n" ); document.write( "Let v = how much of alloy B\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Concentration of x in alloy A, \n" ); document.write( "Concentration of y in alloy A, \n" ); document.write( "Concentration of x in alloy B, \n" ); document.write( "Concentration of y in alloy B, \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "THE MIXTURE TO PREPARE \n" ); document.write( "Concentration of x in mixture, \n" ); document.write( "Concentration of y in mixture, \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Account for material x: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Account for material y: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The \"account\" equations are a system of two linear equations in two unknowns.

The best question, now answered, was HOW MUCH OF ALLOY A AND ALLOY B to use. This ratio is 40 parts of A to 9 parts of B. \n" ); document.write( " \n" ); document.write( " |
