Answer:
4 rolls
Step-by-step explanation:
We can use logic to find how many rolls of toilet paper you would need.
If you use 10 sheets of toilet paper every time you use the toilet, and this happens 3 times a day, then each person per day uses 
sheets of toilet paper per day.
For a 4 family household with 4 people, that would be 
sheets every day for the whole family.
For a week (7 days) the whole family would use 
sheets per week.
If rolls of toilet paper are shipped by every 250 sheets, then we'd need 
rolls.
We can't have 0.36 of a roll, so we round up to 4 so we have enough.
Hope this helped!
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
5m^7
Step-by-step explanation:
The question is 40m^11÷8m^4
So let's solve
(40÷8)(m^11÷m^4)
Division in any exponential is going to be substration
(5)(m^11-4)
(5)(m^7)
5m^7
So the final answer is 5m^7
