Answer:
The number is -3.
Step-by-step explanation:
Set up an equation:
Variable n = number
12 + 7n = n - 6
Assuming the question is solve for n, isolate the variable:
Subtract n from both sides:
12 + 6n = -6
Subtract 12 from both sides:
6n = -18
Divide by 6 on both sides:
n = -3
Check your work:
12 + 7(-3) = -3 - 6
12 - 21 = -3 - 6
-9 = -9
Correct

Answer:
The time is independent of the months we multiply these minutes as grouping with subject impression or importance. This way within the frequency you can see 263340 represents what score you are looking for importance ie) 20/20 for your book choice. This is 8 days which fits better for a monthly review 8,8,8 and 6. Which would easily be readable in the minute totals.
240= 8 nights 180 minutes = 6 nights. Having a frequency helps determine patterns for book interest and study.
Step-by-step explanation:
Subjects (imp) Minutes (M P/D) F(Frequency)
score 1-3 30 60
4-6 60 300
7-9 60 420
10-12 90 990
Total 26 + 240 ...266 x990 = 263340
