perimeter =48
18+18+6+6=48
x-12=x/3
Multiply both sides by 3
3x-36=x
3x=x+36
2x=36
x=18
18-12=18/3
6=6
One side 18 another side 6
Answer:

0+0=0
Answer:
Ahmed has more toffees
Ben has more chocolates
Step-by-step explanation:
Ahmed:
60% = 3/5
3/5 x 30 = 18
therefore out of 30, 18 are toffees.
30 - 18 = 12
therefore 12 are chocolates
Ben:
3/8 x 40 = 15
therefore out of 40, 15 are toffees
40 - 15 = 25
therefore 25 are chocolates
By the way I am not sure!
