20=2(r+7)
i need with this equation

Hi there! :) The answer to your question is 3. First you do parenthesis r=3.
3+7=10, then you do 10*2=20. That is how you solve the problem.

Hope I helped! :)
( Mark as Brainliest Answer! Thank you! :)

20 = 2(r + 7)
20/2 = r + 7
10 = r + 7
10 - 7 = r
3 = r
r = 3

The answer is: r = 3.

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for

The answer would be 13.5 minutes.
