Evaluate: -3/8 + 5/8 + 7/8 , (ii) 11/3 + -5/3 + -2/3 , (iii) -1+ 2/(-3) + 5/6 , (iv) 7/26 + (-11)/13 + 2 , (v) 3+(-7/8) + -3/4 , (vi) -13/8 + 7/16 + (-3)/4

Evaluate each of the following: (i) (2/(11))^4*((11)/3)^2*(3/2)^3 (ii) (1/2)^5*((-2)/3)^4*(3/5)^(-1)

If the coordinates of A, B, C and D are (6,3), (-3,5), (4,-2) and (x,3x) respectively and if (DeltaDBC)/(DeltaABC)=(1)/(2)."then show that"x=(11)/(8)"or"(3)/(8).

If A=[(1,2),(3,-5)] then A^-1 is A. [(-5,-2),(-3,1)] B. [(5/11,2/11),(3/11, - 1/11)] C. [(-5/11,-2/11),(-3/11, -1/11)] D. [(5,2),(3,-1)]
