For this case we must solve the following equation:

We apply distributive property on the right side of the equation:

We subtract 6y on both sides of the equation:

We subtract 6 from both sides of the equation:

Dividing by 6 on both sides of the equation:

So, the result is 
Answer:

Hey there! I'm happy to help!
A proportional equation follows the form y=kx, where k is the constant of proportionality.
Answer 1 is wrong because there is something added.
2 is correct as it follows this format.
3 is incorrect as it does not follow this format.
4 is correct as it follows the format (k is 1)
5 Is correct because it follows this format.
6 is not correct because there is a 1 added, which does not follow the format.
Therefore, the correct answers are 2, 4, and 5.
Have a wonderful day! :D
Answer:
110 pages
Step-by-step explanation:
The rate of 55 pg in 30 minutes is given in "minutes".
Thus,
we need to convert 1 hour to minutes.
We know 1 hour = 60 minutes
Note: 30 mins * 2 = 60 minutes
Logically, 30 minutes makes 55 pages, so 60 minutes (30 * 2) will make 55 * 2 = 110 pages
So, in 1 hour, it can print 110 pages (at this rate)
