First we have to collect the like terms (The terms with the same variables) on the same side so it becomes:
5p-2p=12+9
Then you simplify it by combining the like terms so it becomes:
3p=21
Now you simplify by dividing both sides by 3 and it becomes:
p=7

Hope this helps :)

Debora [2.8K]

Answer:

$r = 1036.725\,mi$

Step-by-step explanation:

The distance per unit grade on Earth is:

$\Delta s = \frac{2\pi\cdot (3960\,mi)}{360}$

$\Delta s \approx 69.115\,miles$

The distance between Pittsburgh and Miami is:

$r = (69.115\,mi)\cdot (40.5^{\textdegree}-25.5^{\textdegree})$

$r = 1036.725\,mi$
