I believe 5 is 3 inches per year because 57 minus 40 and 1/2 is 16 and 1/2, so you divide 16 and 1/2 by 5 and 1/2 which equals 3, so 3 inches per year
You make 2 2/7 an improper fraction (16/7) and then you subtract 8/7 from 16/7 and you get 1 1/7 (or 8/7) as your final answer

Step-by-step explanation:
Ok so let’s write out the problem
4x+6=-x+1
We first want to get the x’s on one side and the numbers on the other
4x+6=-x+1
+x. +x
5x+6=1
Now we want to get the 6 over
5x+6=1
-6. -6
5x=5
Divide by 5 to get the x alone
X is equal to 1
