Answer: 85/12 fewer bushels per acre
Step-by-step explanation:
Hi, to answer this question we have to write an expression with the information given and solve it:
We simply have to divide the total loss (21 1/4) by the number of acres (3):
Mathematically speaking:
21 1/4 ÷3 = (21(4) +1)/4 ÷3 = 85/4 ÷ 3= 85/12 fewer bushels per acre

Answer:
AB = b - a
![OP = \frac{3}{4} b \: + \frac{1}{4} a](https://tex.z-dn.net/?f=OP%20%3D%20%20%5Cfrac%7B3%7D%7B4%7D%20b%20%20%20%5C%3A%20%20%2B%20%20%5Cfrac%7B1%7D%7B4%7D%20a)
Step-by-step explanation:
AB = -OA + OB
AB = -a + b we usually write the positive vector first
AB = b - a
We know that P divides AB in the ratio 3:1 so PB = 1/4 AB
AB is negative as we are going in the opposite direction
OP = OB - 1/4 AB
OP = b - 1/4 (b - a)
multiplying inside the brackets:
OP = b - 1/4b + 1/4a
OP = 3/4b + 1/4a
