Hello User
To do this we need to first add all of the numbers together.
-18 + -14 + 11 + 13 = -8
The next step is to divide the result by how many pairs of numbers there are.
As you can see there are 4 pairs of numbers
So we divide -8 by 4 to get -2
Therefore -2 is the answer to this problem
I hope I helped :-)

Answer:
10 miles
Step-by-step explanation:
Given: Boat goes
hours with 8 mph (i)
Boat goes
hours with 12 mph (ii)
Now, lets find out distance separately to get total distance.
Formula for finding distance is
D= 
D=
(i)
D= 
∴ D1= 6 miles (i)
D=
(ii)
∴D2= 4 miles (ii)
To find total distance, we will add d1 and d2
Total distance = 
∴ Total distance = 
= 10 miles is the total distance covered by boat in all this time.
56.30
With a calculator, press second or shift and then tan to find the degrees.
It has one solution Bc there is only one variable
