Answer:
A
Step-by-step explanation:
The Fibonacci sequence is the sum of the two terms before it. It looks like this:
1, 1, 2, 3, 5, 8, 13, 21, 34, ...
As you can see, 13 and 21 are indeed consecutive terms.
520
= 650 - (97.50 + 97.50/3)
= 650 - 130
= 520
180/4 is 45 so you could say the farmer plants 135 Acers of corn and only 45 of wheat
3x+y=180
Hope this helped.
