Answer:
15 minutes per hour
Step-by-step explanation:
Given that:
Phone usage limit = 3 hours
As 1 hour = 60 mins so, 3 hours = 3 * 60 = 180 mins
Now:
Phone usage limit = 180 mins
She is up for 12 hours, So:
Minutes per hour for mobile usage = 180/12 = 15 mins per hour
So if Avery is up for 12 hours she can use her mobile phone 15 mins per hours according to given usage limit.

Answer:
Step-by-step explanation:
U have to multiply 49 by 49 and then subtract 9
An easy way is to do this
the 2 numbers are -x and x+8 where x is an integer
we can generate lots of numbers this way
example
-1 and 9
-2 and 10
6x + 9
First, simplify x
3x + -3x + 5x = 6x
Then, simplify the rest of the numbers:
2 + 7 = 9
Then make the equation:
6x + 9
