Answer:

Here we want to solve the equation:

11^3\sqrt{x-12} = 66

First, we can divide both sides by 11^3 to get:

(11^3\sqrt{x-12})/11^3 = 66/11^3

\sqrt{x - 2} = 66/11^3

Now remember that:

(√x)^2 = √(x^2) = x

then if we apply this to our equation we get:

(\sqrt{x - 2})^2 = (66/11^3)^2

now we need to solve:

x - 2 = (66/11^3)^2\\x =  (66/11^3)^2 + 2 = 2.002

Then x = 2.002

A ferry traveled 1 6 6 1 ​ start fraction, 1, divided by, 6, end fraction of the distance between two ports in 3 7 7 3 ​ start f
docker41 [41]

Answer:

\frac{7}{18} of the distance

Step-by-step explanation:

We know that a ferry traveled \frac{1}{6} of the distance between two ports in \frac{3}{7} hours.

In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :

The rate of the ferry is the same at any time.

The ferry will travel \frac{1}{6} of the distance in \frac{3}{7} hours.

If we divide each fraction by 3 ⇒

\frac{\frac{1}{6}}{3}=\frac{1}{18} and \frac{\frac{3}{7}}{3}=\frac{1}{7}

We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :

The ferry will travel \frac{1}{18} of the distance in \frac{1}{7} hours.

Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒

(\frac{1}{18}).7=\frac{7}{18} and (\frac{1}{7}).7=1

We found out that the ferry will travel \frac{7}{18} of the distance in 1 hour.

Answer corecctly plss<br> 7(2+5v0=2v+14
Radda [10]

Answer:

v=0

Step-by-step explanation:

I think you mean 7(2+5v)=2v+14.

14+35v=2v+14 distribute

33v=0  Subtract 2v and 14

v=0 divide by 33 on both sides

Hope this helps plz mark brainliest if correct :D
