Answer:
Step-by-step explanation:
You add the like-terms so the things that are the same, pretty much.
so 3t^2+7t^2 = 10t^2
and you can subtract 8t^2 from 10t^2 because they are like terms so you get 2t^2
then bring -5t down and subtract 9 from 6 and boom you're done
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 = 
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 =
Simplify the fraction to get the speed.
= 16.
Your final equation is:
Speed = 16.
Our final answer is
16 mph.I hope this helps!
