Answer:
-85.9 feet below sea level.
Step-by-step explanation:
The slope (m) = -13.
We can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Let (x1, y1) = (7, 26)
(x2, y2) = (12, -39)
Plug in the values into the formula:
m = (y2 - y1) / (x2 - x1)
m = (-39 - 26) / (12 - 7)
m = -65/5
m = -13
The LCD of 11/20 and 31/45 is 180
20 40 60 80 100 120 140 160 180
45 90 135 180
The first dove terms are:3,9,12,15,18
