You can use the on-site calculator to solve this.

Simply distribute the -3 and 2 first.

Then, collect "like" terms and that's it! For example, 2x + x = 3x & -2v + 3v = 1v = v.

You should be able to do this now!

-27 = -6 - p

First, add 6 to both sides since you want to solve for p!

-21 = -p.

Note that we have -p and not p. So, we have to divide both sides by -1 giving us our final answer:

p = 21.

s = d/t

s = 300*10^5 / 3.5*10^8

Now, we can simply cancel out 10^5 and convert 10^8 to 10^3 since 8-5 = 3. Note that 10^3 is in the denominator meaning we move the decimal place 3 times to the left. 

Also, we can just normally divide 300 by 3.5 (same as 7/2): 300 * 2 / 7 = 600/7. Since 600/7 is in the numerator, we can take its decimal and move the decimal place 3 times to the left.

So, we end up with 600/7 * 10^-3 unit/unit [m/s for example] = ~0.0857 unit/unit.

Think of 2.4 as 24. How do we get from 2.4 to 24?? 

Notice that you have to move the decimal place to the right once. This is the same as multiplying by 10. So, if we want to get 2.4, we have to divide 24 by 10!

24/10 = 2.4

Now, we just have to simplify 24/10 by dividing both the numerator and denominator by 2:

12/5.
