5+4+3=12. 72/12=6. 3(6)=18. 4(6)=24. 5(6)=30. area of right-angled triangle = 1/2 x b x h. 1/2 x 24 x 18= 1/2 x 24 x 9. 24x9 = 216.

10kg/500g= 20 bags20 bags x £1.30= £26 (money made)£26-£20= £6 (profit)(£6/£20)*100= 30% (percentage profit)

first you want to remove the fraction, so must multiply both sides of the equation by 2, giving: 5 - x = 4x - 14. Then you want to group all of the x's on one side, so will move x to the right where the s...
