21 hrs. Because if Harry worked one third the hrs thats Aiden worked then 7×3 =21 and 21÷3=7. So 7 is one third of 21.
What I did was trial and error. (There is a mathematical way to do this but...)
so you have 10*12 and that equals 120. That is the area of the photo. With the frame, the area is 288.
Increase each number as so:
11*13=143.......continue trial and error
16*18=288
answer: 16
Hope that helps!
We must solve

Means the candles will be the same size in 4 hours
Printed pages in 11 minutes = 33 pages
Printed pages in a minute = 33/11
= 3 pages/minute
Answer:
D
Step-by-step explanation:
So we are given the limit:

To figure out this limit, we can use direct substitution. Simply substitute 0 for x and then simplify. Therefore:

Therefore, the limit equals 10.
