First sequence with common difference:
8-x=y-8
Second sequence:
20-y=y-x
Solving two simultaneous equations:
x=16-y
20-y=y-16+y
y=12
x=4
Answer:
I think the answer is 9+ 7x + (3y) dont quote me on that though
36. 1/4, it will take 4 to equal a pound. Because you want 8 pounds, multiply it by 8. 8x4=36
