Hello
<u>Let's note the original speed of the car v</u>
it means that in 1 hour he is going v miles
so to go 200 miles it takes ( in hour)

If the speed of the car is v+5 than to go 200 miles it takes (in hour)

and this time is one hour less so we can write

We can multiply by v(v+5) both parts of the equation so


Only one is positive and this is is

So the original speed is 29.22144... mph
Hope this helps.
Do not hesitate if you need further explanation.
Thank you

Answer:
The answer is 15 Shirts
Step-by-step explanation:
We want to know what x is going to equal that makes the equation the same.
First, I make the euations equal to each other by substituting the y -->
7x + 50 = 10x + 5
Then, I combine my similar terms --> 45 = 3x
After that, I divide by 3 to get x on its own -->
--> 15 = x
This means that after 15 Shirts are sold, the costs for both companies are the same.
For the first one is has greater then 3 terms
The middle one is has exactly one term
And the last one is has two terms
I believe I hope this helps
