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

Step 1) Begin by moving the terms; move the variable to the left side
and change its sign. -8x+6x+3=11.
Step 2) Collect the like terms.
-2x=11-3.
Step 3) Divide both sides of the equation by -2.
Answer: x=-4
Let t = number of hours
The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t
The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t
You want the lengths to be equal, so the equation is
8 - (7/10)t = 6 - (1/5)t
Combine like terms
6x + 9 - 16x
6x - 16x = -10x
-10x + 9 = -21
-9 -9
-10x = -30
-10x/-10 = -30/-10
x = 3
Answer: x = 3
