Algebra.Com's Answer #321873 by Theo(13342) You can put this solution on YOUR website! Ananda wanted to determine the average of her 6 test scores.She added the scores correctly to get T ,but divided by 7 instead of 6 .The result was 12 less than her actual average . Which equation coule be use to determine the value of T? \n" ); document.write( "A) 6T+12=7T \n" ); document.write( "B) (T/7)=(T-12)/6 \n" ); document.write( "c) (T/7)+12=T/6 \n" ); document.write( "D)( T/6)+[(T-12)/7] \n" ); document.write( "----- \n" ); document.write( "your solution is C. \n" ); document.write( "T/7 + 12 = T/6 \n" ); document.write( "This equation is arrived at in the following manner: \n" ); document.write( "The average she should have gotten is given by the equation: \n" ); document.write( "A = T/6 \n" ); document.write( "Instead she got an average using the following formula: \n" ); document.write( "A = T/7 \n" ); document.write( "This Average is 12 less than the average she would have gotten had she divided by 6. \n" ); document.write( "The equation for that relationship is: \n" ); document.write( "T/7 = (T/6) - 12 \n" ); document.write( "If you add 12 to both sides of this equation, you get: \n" ); document.write( "(T/7) + 12 = (T/6). \n" ); document.write( "That's selection C. \n" ); document.write( " \n" ); document.write( " |
