The total elevation that the scuba driver does is from

to

The ascending distance =

The ascending distance =

The time (t) taken during the ascend = 19.125 - 12.75 = 6.375 minutes
The average change in speed is given by the ascending distance divided by time taken during the ascend =

÷ 6.375 = 0.125 feet/minute
Answer:
Step-by-step explanation:
Perimeter is twice the sum of the length and width
P=2(L+W), in this case
P=2(4x+6+3x+4)
P=2(7x+10)
P=14x+20
The answer could be A plzzzz tell me if im wrong.

Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
