Answer:
f(8)=20..The answer is 8 :)
Don’t take my word for it but if there’s no x then it might be undefined.
Sorry if I’m incorrect
So first let’s make them improper. that will then make the equation 10/3 divided by 5/2 then you want to flip one so you can divide... that would be 3/10 divided by 5/2 and then you multiply across and get 10/6

Answer: 8 miles</h3>
=======================================================
Work Shown:
x = number of miles
2x = cost of traveling x miles, at $2 per mile, without including the $3 fee
2x+3 = total cost now including the $3 entrance fee, without tip
2x+3+1 = total cost plus $1 tip
2x+4 = amount you spent
2x+4 = 20
2x = 20-4
2x = 16
x = 16/2
x = 8
You traveled 8 miles.
You set it up like this.
It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
