Use synthetic division. (2) Mariam went to a stationery and bought 8 notebooks, 3 pens and 3 stickers. She paid 8 BD totally. Her friend Zainab bought 4 notebooks, 9 pens and 4 stickers. She paid 10.9BD. (5 marks) Is it possible to know the cost of each stationery mathematically? "If yes how. If not why? I (3) Solve the equations and combine identical sides (5 marks). What is the resultant shape using all the figures? (5marks) 4x+1 = x+2 2(x-9)=9-(4x-3) x+29=2(x-1) 3 3x-4=x 3(x+2)=4(x+1)-3 2x+2+4x=3(x+5) (x+4)-3x=-2 3(x-4)=4-(2x+1) (4) Create your own problem using physical quantities on inverse variation. I Design a formula using the concepts of variation (5 marks) and solve that problem and state conclusion. (5 marks)
