Yoghurt __________ No of responses
Low Fat ___________ 15
Greek_____________24
Whipped __________ 10

= 0.4 * 100%
= 40%
A rhombus is quadrilateral where all 4 sides are of equal length. Thus
5x + 2 = 2x + 12
3x = 10
x = 10/3
substituting x into either expression, yields
56/3
therefore side AB = 56/3

19. -0.75
20. -4/10 = -0.4
