The distance between the police station and the fire station is x.
The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station, so it is 2x-3. This distance is equal to 5 miles.
The police station and the fire station are 4 miles aparat.

I will attach google sheet that I used to find regression equation.
We can see that linear fit does work, but the polynomial fit is much better.
We can see that R squared for polynomial fit is higher than R squared for the linear fit. This tells us that polynomials fit approximates our dataset better.
This is the polynomial fit equation:
I used h to denote hours. Our prediction of temperature for the sixth hour would be:

Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *
= 67
0.3 * = 30
Divide as usual.
67 / 30 = 2
So, the answer is 2 1/3.

Answer:
Step-by-step explanation:
For this exercise it is important to remember the multiplication of signs:
In this case, given the following expression:
You can idenfity that both factors are negative. Then, the product (The result of the multiplication) will be positive.
Then, in order to get the product, you need to multiply the numerator of the fraction by -8. So, you get:
You can notice that the numerator and the denominator of the fraction obtained cannot be divided by the same number; therefore, the fraction cannot be simplified.
