Algebra.Com's Answer #202624 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! We all agree that c+m+e=1200 \n" ); document.write( "There are twice as many in electrical engineering (e) as in mechanical engineering, and \n" ); document.write( "Does this mean 2e=m or 2m=e?\r \n" ); document.write( "\n" ); document.write( "three times as many in chemical engineering (c) as in mechanical engineering (m). \n" ); document.write( "Does this mean 3c=m or 3m=c?\r \n" ); document.write( "\n" ); document.write( "We can eliminate other choices such as 3m=e in B) and 3m=2e in D) \n" ); document.write( "So now we need to choose between \r \n" ); document.write( "\n" ); document.write( "A)c+m+e=1200,2m=e,3m=c \n" ); document.write( "C)c+m+e=1200,2e=m,3c=m \n" ); document.write( " \n" ); document.write( "Does \"There are twice as many in electrical engineering (e) as in mechanical engineering\" mean there are more e or more m? \n" ); document.write( "There are more e so it would take 2m to equal e or 2m=e\r \n" ); document.write( "\n" ); document.write( "So A) is the answer so far. \n" ); document.write( "three times as many in chemical engineering (c) as in mechanical engineering \r \n" ); document.write( "\n" ); document.write( "Are there more c or more m \n" ); document.write( "There are more c than m \n" ); document.write( "so it would take 3m to equal c or 3m=c \n" ); document.write( "which again is in A)\r \n" ); document.write( "\n" ); document.write( "there are 200 mechanical engineers\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
