Answer:

Step-by-step explanation:

First question

1 solution

6p-12= - 5p Take 6p from both sides
-12 = -5p - 6p Combine
-12 = - 11p Divide by - 11
-12/-11 = p
1.09 = p

Second Question

Infinitely many solutions.
5p + 10 = 5p + 10
No matter what value you use for p, the right side of the equation always equals the left side.

Third question

y = 25 - 2x
x = 6
y = 25 - 2*6
y = 25 - 12
y = 13

There are 13 more stops to make.

Select the correct answer.

Answer:

$v=\sqrt{\frac{E}{m}}$

Step-by-step explanation:

The formula is given as:

$E=mv^2$

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

$E=mv^2\\\frac{E}{m}=\frac{mv^2}{m}\\\frac{E}{m}=v^2$

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

$\frac{E}{m}=v^2\\\sqrt{\frac{E}{m}}=\sqrt{v^2}\\\sqrt{\frac{E}{m}}=v$

Putting v to left side (convention), we finally have:

$v=\sqrt{\frac{E}{m}}$
