You can put this solution on YOUR website!
After changing the percentages to decimals, you can set up your equation as follows: x = number of grams of the 35% Ni alloy. (35% = 0.35, 65% = 0.65, 41% = 0.41)\r
\n" ); document.write( "\n" ); document.write( "\"x%280.35%29+%2B+%2820+-+x%29%280.65%29+=+%2820%29%280.41%29\" Simplify and solve for x.\r
\n" ); document.write( "\n" ); document.write( "\"0.35x+%2B+13+-+0.65x+=+8.2\" \r
\n" ); document.write( "\n" ); document.write( "\"-0.3x+%2B+13+=+8.2\" Subtract 13 from both sides.\r
\n" ); document.write( "\n" ); document.write( "\"-0.3x+=+-4.8\" Divide both sides by -0.3\r
\n" ); document.write( "\n" ); document.write( "\"x+=+16\"\r
\n" ); document.write( "\n" ); document.write( "16 grams of 35% Ni alloy are required.\r
