Algebra.Com's Answer #77289 by ptaylor(2198) You can put this solution on YOUR website! Let x=amount that Brian earns as a tutor---weekly wages \n" ); document.write( "Then (x/2)=amount that Brian earns pumping gas \n" ); document.write( "So x+(x/2)= Brian's total weekly wages \n" ); document.write( "And (x/4)=amount that Brian's sister earns\r \n" ); document.write( "\n" ); document.write( "Now we are told that:\r \n" ); document.write( "\n" ); document.write( "x+(x/2)=(x/4)+150 multiply both sides by 4\r \n" ); document.write( "\n" ); document.write( "4x+2x=x+600 subtract x from both sides\r \n" ); document.write( "\n" ); document.write( "4x+2x-x=x-x+600 collect like terms\r \n" ); document.write( "\n" ); document.write( "5x=600 divide both sides by 5\r \n" ); document.write( "\n" ); document.write( "x=$120------Brian's weekly wages as a tutor \n" ); document.write( "(x/2)=(120/2)=$60-------------------Brian's weekly wages pumping gas\r \n" ); document.write( "\n" ); document.write( "(x/4)=(200/4)=$50 ----------- Brian's sister's weekly wages\r \n" ); document.write( "\n" ); document.write( "CK\r \n" ); document.write( "\n" ); document.write( "$120+$60=$30+$150\r \n" ); document.write( "\n" ); document.write( "$180=$180\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
