Algebra.Com's Answer #296976 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! Let x = the (first) lowest number \n" ); document.write( "Then the other numbers are x+1, x+2 and x+3 \n" ); document.write( "Given: sum is less than 5 times the first. \n" ); document.write( "In equation form this is: \n" ); document.write( "x + x+1 + x+2 + x+3 = 5x - 15 \n" ); document.write( "Now collect terms and solve for x: \n" ); document.write( "4x + 6 = 5x - 15 -> x = 21 \n" ); document.write( "So the 4 numbers are: \n" ); document.write( "21, 22, 23, 24 \n" ); document.write( "Check: \n" ); document.write( "21 + 22 + 23 + 24 = 90 \n" ); document.write( "5(21) = 105 \n" ); document.write( "105 - 90 = 15, so sum is 15 less than 5 times the first \n" ); document.write( " \n" ); document.write( " |
