Algebra Review Welcome Example Student taking  Psy 527 899 - Spring, 2007     Score = 0  Your assignment appears below.      Perform the indicated operations. Express the answer in decimal form. ( 11 / 31 ) * ( 81 / 45 ) = ( 90 / 82 ) + ( 66 / 93 ) = 2-9.7 = ( 63 / 8 ) ( 0.9 + 0.6 ) = ( 8 / 44 ) ( 9 / 30 ) = Evaluate the following - use a= 4, b= 2, and c= 3 ((a-b)/c)-((a+c)*(a/b)) = ((c2 - b) * (b3 - c)) * (c2 + b3) = ((cb - bc) - (ba - c)) + (c(b-a) + 2.137(b/a)) = Simplify the following using variables rather than numbers - these items are not graded (a-b)2 = a-(b+c)2 = (ab + cd)2 = ((c-d)(-a) + (ac-d)) / (a-1) = (cab-dba)/(ab(d-c)) = Fill in the following table X Y X+Y X-Y (X-Y)2 (X-Y)/(X+Y) ((X-Y)/(X+Y))2 60 96 ? ? ? ? ? 55 64 ? ? ? ? ? 5 82 ? ? ? ? ? 8 84 ? ? ? ? ? 77 34 ? ? ? ? ? 80 17 ? ? ? ? ? 59 62 ? ? ? ? ? 5 31 ? ? ? ? ? 91 21 ? ? ? ? ? 45 91 ? ? ? ? ?
