Isolate the w. Note the equal sign. What you do to one side, you do to the other.
First, multiply w to both sides
(V/w)w = 9(w)
V = 9w
Next, Isolate the w. Divide 9 to both sides
V(/9) = 9w(/9)
w = V/9
w = V/9 is your answer

Answer:
8 minutes
Step-by-step explanation:
Step one:
given
A submarine is 105 feet below the surface of the water
depth of submarine= 105 feet
let the time of ascending be x
Required
The time taken to ascend up to 81 ft
Step two:
the expression for the situation is
<em>81=105-3x</em>
solve for x
3x=105-81
3x=24
divide both sides by 3
x= 24/3
x=8 minutes

Answer:
13.2 miles
Step-by-step explanation:
To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.
(5.5 + 3.5)² + b² = 15²
9² + b² = 15²
81 + b² = 225
b² = 144
b = 12
Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).
5.5² + 12² = c²
30.25 + 144 = c²
174.25 = c²
13.2 ≈ c
Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.
