Algebra.Com's Answer #130323 by gonzo(654)![]() ![]() ![]() You can put this solution on YOUR website! 7182 were killed in last night's frost. \n" ); document.write( "this was 2 and 5/8 as many as the night before. \n" ); document.write( "how many roses were killed the night before. \n" ); document.write( "--- \n" ); document.write( "let x = number of roses killed the night before. \n" ); document.write( "then: \n" ); document.write( "7182 = 2 and 5/8 times x. \n" ); document.write( "--- \n" ); document.write( "since 2 = 16/8, this is the same as: \n" ); document.write( "7182 = 21/8 * x \n" ); document.write( "multiply both sides of this equation by 8 to get: \n" ); document.write( "7182 * 8 = 21 * x \n" ); document.write( "divide both sides of this equation by 21 to get: \n" ); document.write( "x = 7182 * 8 / 21 \n" ); document.write( "--- \n" ); document.write( "this makes x = 2736 which means 2736 were killed the night before. \n" ); document.write( "--- \n" ); document.write( "go back to your original problem statement. \n" ); document.write( "7182 roses were killed last night. \n" ); document.write( "this is 2 and 5/8 times the number killed the night before. \n" ); document.write( "the number killed the night before is 2736. \n" ); document.write( "2 and 5/8 times 2736 = 2.625 times 2736 = 7182 \n" ); document.write( "---\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
