x = 3
She bought N pencils last month for 288, as the amount is in pennies. This month she bought N+12 for 720.
288/N = 720 / (N+12)
288(N+12) = 720N
288N + 3456 = 720N
3456 = 720N - 288N
3456=432N
N=8
She bought 8 pencils last month for 288, which is 36 cents each. And she bought 20 pencils this month for 720 which is 36 cents each. Hope this helped :)
Answer:

Find the LCM and multiply to get there.
LCM is 60
63/60-16/60
47/60
Answer:
83
Step-by-step explanation:
Let the number of robbers be x
If they share 6 rolls each, the tota rolls will be 6x and since they have five remainder, the overall total is then 6x+5
In case they share 7 rolls each, it means they have 7x rolls but here they will be less 8 rolls hence 7x-8 is the overall total.
Equating these two
7x-8=6x+5
Arranging similar terms
7x-6x=8+5
x=13
Therefore, the robbers are 13
The rolla they have will be
6(13)+5=83
Or
7(13)-8=83
Subtract the one value from 180 and then divide that number by 2 to get the 2 values. So if one side is 90, they other sides would be 45 each
