Algebra.Com's Answer #243214 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A plane was originally flying at an altitude of x feet when it ascended 2000 feet and then descended 5000 feet. If the plane's altitude after these two chages was 1/3 its original altitude, then the solution of which of the following equations gives the plane's original altitude, in feet? \n" ); document.write( "---- \n" ); document.write( "start: x \n" ); document.write( "ascend 2000: x+2000 \n" ); document.write( "decend 5000: x+2000-5000 \n" ); document.write( "result: x-3000 \n" ); document.write( "Equation \n" ); document.write( "x-3000 = (1/3)x \n" ); document.write( "--- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "========================= \n" ); document.write( "(A) x+2000=1/3(x-3000) \n" ); document.write( "(B) 1/3(x-3000)=x \n" ); document.write( "(C) x+3000=1/3x \n" ); document.write( "(D0 x-7000=1/3x \n" ); document.write( "(E) x-3000=1/3x \n" ); document.write( " \n" ); document.write( " |
