18 = 10 + 2k

move 10 to the other side

sign changes from +10 to -10

18-10=10-10+2k

18-10= 2k

8= 2k

divide by 2 to get k by itself

8/2= 2k/2

Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k

k=8/2

Answer: k= 4

The speed of a ship is given by d3, where d is the distance the ship travels in 3 hours. if the ship travels 48 miles in 3 hours
Kay [80]
Hello there! Thank you for asking your question here at Brainly! I will be assisting you today with answering this problem, and will teach you how to handle it on your own in the future.

First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"

To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed = \frac{Distance}{Time}

Now that we have our formula, let's define our variables.

So, we have our distance, 48 miles, and our time, 3 hours.
Let's plug in these numbers to the formula.
Speed = \frac{48}{3}

Simplify the fraction to get the speed.
\frac{48}{3} = 16.

Your final equation is:
Speed = 16.

Our final answer is 16 mph.

I hope this helps!
