To find the number of years between 1844 to 2015 you have to subtract.
Lets say that x is the # of years in between 1844 and 2015
Then we have:

After doing the subtraction using a calculator or a pencil and paper, you get that:

So 171 years have passed from 1844 to reach to 2015.
Answer:
-5, 5
Step-by-step explanation:
The line in this problem can be written in the form
(1)
where:
is the slope
q is the y-intercept
We know that the line passes through the point (-2,5), so substituting these values into eq.(1), we find the value of the y-intercept:

So the equation of the line is
(2)
Now we know that point A has coordinates
A(x,3)
So by substituting into eq.(2), we find the missing x-coordinate:

Similarly, point B has coordinates
B(-2,y)
so substituting into eq(2), we find the missing y-coordinate:

Answer:
40/100 * x = 40
Solve for x. Hope this helps
The answer will be 27 only.
The answer for this problem is -8x+2
