Garage A charges $11 for the first 2 hours of parking there and then $3 per hour after the first 2 hours. Garage B charges $4 pe
laiz [17]

Answer: it would take 22 hours before you pay the same amount for both Garages.

Step-by-step explanation:

Let x represent the number of hours that you park at either Garage A or Garage B

Let y represent the total amount paid for x hours at Garage A

Let z represent the total amount paid for x hours at Garage B

Garage A charges $11 for the first 2 hours of parking there and then $3 per hour after the first 2 hours. This means that the total amount for x hours would be

y = 2 × 11 + 3x

y = 22 + 3x

Garage B charges $4 per hours. This means that the total amount for x hours would be

z = 4x

To determine the number of hours before the amount for both Garages becomes the same, we would equate y to z. It becomes

22 + 3x = 4x

4x - 3x = 22

x = 22

THIS QUESTION IS EASY, I JUST NEED EXPLANATION.
chubhunter [2.5K]

It would help to have the question. But I'll guess


\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}} = ((x^{\frac 3 5})^{\frac 1 4}) }{ x} = x^{\frac 3{20}} x  = x \sqrt[20]{x^3}


2nd choice.


I forgot the explanation because I was so glad to have puzzled out the question.

The fourth root is the same as the 1/4 th power.   

If we know x is positive \sqrt{x^2}=|x|=x

\sqrt[4]{x^{\frac 3 5}}{\sqrt{x^2}}

= ((x^{\frac 3 5})^{\frac 1 4}) }{ x}

We multiply the powers: (a^b)^c=a^{bc}

= x^{\frac 3{20}} x

The one-twentieth power is the twentieth root.  We bring the additional factor of x to the front.

= x \sqrt[20]{x^3}
