Algebra.Com's Answer #599639 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! consecutive ages are 4x, 4(x+1), 4(x+2) \n" ); document.write( "4x-3 + 4x+4-3 + 4x+8-3 < 39 \n" ); document.write( "4x-3 + 4x+1 + 4x+5 < 39 \n" ); document.write( "12x + 3 < 39 \n" ); document.write( "12x < 36 \n" ); document.write( "x < 3 \n" ); document.write( "There are two solutions to this problem \n" ); document.write( "************************************** \n" ); document.write( "1) x = 2 \n" ); document.write( "ages are 8, 12, 16 \n" ); document.write( "5 + 9 + 13 < 39 \n" ); document.write( "27 < 39 \n" ); document.write( "************************************** \n" ); document.write( "2) x = 1 \n" ); document.write( "ages are 4, 8, 12 \n" ); document.write( "1 + 5 + 9 < 39 \n" ); document.write( "15 < 39 \n" ); document.write( "*************************************** \n" ); document.write( " |
