Answer:
a=7
Step-by-step explanation:
24^2+a^2=25^2
576+a^2=625
49=a^2
a=7
We must create the equation from the information. Well, we know that there is a 75 dollar fee right off the top, and there is the word "plus" in the information meaning there will be adding.
1. Add the given cost plus the addition sign.
75 + ___ = ?
Now, we must find out what fills in "__." It says that it costs $20 per hour to rent the limo. However, it doesnt tell you how many hours it is being rented for, however it does say that the amount of hours is represented by T. So, fill in that information.
2. Fill in the second number.
75 + 20T = ?
Since there isn't a number to finish the second number to the equation, we know that there isn't going to be a completed answer. So, fill in the final cost with "c" as explained in the equation.
3. Write the answer.
75 + 20T = c
So, the equation to this problem is:
75 + 20T = c
Which is how to find out how much the limo costs to rent it.
