<u><em>X = 5</em></u>
[|] Explanation [|]
Subtract 5 From Both Sides:
X + 5 - 5 = 2x - 5
Simplify:
X = 2x - 5
Subtract 2x From Both Sides:
X = 2x - 2x - 5 - 2x
Simplify:
-x = -5
Divide Both Sides by -1:
-x/-1 = -5/-1
Simplify:
X = 5

Answer:
Translation 6 units left and 3 units down
Step-by-step explanation:
So, you start off with $3.50 you travle 6 miles every mile is 0.75 that means you would need to multiply 6 by 0.75.
6
0.75
it equals 4.5
So we have $4.50 we need to add $3.50 and in total $0.50 plus $0.50 would be a dollar + 3 dollars plus $4 would be 7 so 7 +1 is 8. and 8 is the answer.
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
