Algebra.Com's Answer #265647 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! There are two numbers whose sum is 72. One number is twice the other. What are the numbers? \n" ); document.write( ". \n" ); document.write( "Let x = first number \n" ); document.write( "then from \"One number is twice the other.\" we have \n" ); document.write( "2x = second number \n" ); document.write( ". \n" ); document.write( "From: \"There are two numbers whose sum is 72\" we derive our equation: \n" ); document.write( "x + 2x = 72 \n" ); document.write( "3x = 72 \n" ); document.write( "x = 24 (first number) \n" ); document.write( "Second number: \n" ); document.write( "2x = 2(24) = 48 \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "Also. There are three consecutive integers. the sum of the smallest and largest is 36. \n" ); document.write( ". \n" ); document.write( "Let x = first consecutive integer \n" ); document.write( "then \n" ); document.write( "x+1 = second consecutive integer \n" ); document.write( "x+2 = third \n" ); document.write( ". \n" ); document.write( "From:\"the sum of the smallest and largest is 36\" we get: \n" ); document.write( "x + x+2 = 36 \n" ); document.write( "2x+2 = 36 \n" ); document.write( "2x = 34 \n" ); document.write( "x = 17 (first) \n" ); document.write( ". \n" ); document.write( "Second: \n" ); document.write( "x+1 = 17+1 = 18 \n" ); document.write( ". \n" ); document.write( "Third: \n" ); document.write( "x+2 = 17+2 = 19 \n" ); document.write( " \n" ); document.write( " |
