Answer:
the annual rate of inflation r is 0.023
Step-by-step explanation:
Given by the expression:

The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.
Let 

n = 2013 - 1913 = 100
replacing our values into the given equation; then the annual rate of inflation r is as follows:

r = 0.023
Hence, the annual rate of inflation r is 0.023
Answer:
it is because 20 + 20 is 40 and then 40 - 20 = 20
Answer:
x=6
Step-by-step explanation:
5x-10=2x+8
subtract 2x on both sides
3x-10=8
add 10 on both sides
3x=18
x=6
Here's a graph. Remember that the y intercept crosses the y axis.
What is 75-50, then you subtract that answer from 180, because if it’s a triangle, all 3 sides should equal to 180
