What is the first step to solve the equation A. Square both sides of the equation. B. Add 5 to both sides of the equation. Squar
e. 5, and -3. C. D. None, because there is no solution. 2x-5--3?

Hi :)
I'd start by adding 5 to both sides of the equation. That would make the equation easier.
![\boldsymbol{\sqrt{2x}-5=3}}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B%5Csqrt%7B2x%7D-5%3D3%7D%7D)
![\boldsymbol{\sqrt{2x}=2}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B%5Csqrt%7B2x%7D%3D2%7D)
The next step is to get rid of the radical sign.
Which operation will undo the square root? Squaring.
So that's why we square both sides:
![\boldsymbol{2x=4}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B2x%3D4%7D)
And Now we just divide both sides by 2
![\boldsymbol{x=2}](https://tex.z-dn.net/?f=%5Cboldsymbol%7Bx%3D2%7D)

Answer:
It would take him 60 minutes to run 20 laps.
Step-by-step explanation:
We can solve using proportions.
![\frac{9 \: laps}{27 \: minutes} = \frac{20 \: laps}{x} \\ \\ \frac{540}{9} = \frac{9x}{9} \\ \\ 60 = x](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%20%5C%3A%20laps%7D%7B27%20%5C%3A%20minutes%7D%20%20%3D%20%20%20%5Cfrac%7B20%20%5C%3A%20laps%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B540%7D%7B9%7D%20%20%3D%20%20%5Cfrac%7B9x%7D%7B9%7D%20%20%5C%5C%20%20%5C%5C%2060%20%3D%20x)
