Answer:
90 minutes
Step-by-step explanation:
Assuming the time is proportional to the number of pages, you have ...
time/pages = 20/6 = T/27
Multiplying by 27 gives ...
T = 27(20/6) = 90
It is expected to take 90 minutes to check 27 pages.
Answer:

and y = ![e^{t}](https://tex.z-dn.net/?f=e%5E%7Bt%7D)
Note that
x =
=
×
= y²
Thus x = y²

Answer:
WT=63
Step-by-step explanation:
![\frac{56}{5 \times x + 3} = \frac{40}{4 \times x - 3} \\ x = 12](https://tex.z-dn.net/?f=%20%5Cfrac%7B56%7D%7B5%20%5Ctimes%20x%20%2B%203%7D%20%20%3D%20%20%5Cfrac%7B40%7D%7B4%20%5Ctimes%20x%20-%203%7D%20%20%5C%5C%20x%20%3D%2012)
So
![5 \times x + 3 = 5 \times 12 + 3 = 63](https://tex.z-dn.net/?f=5%20%5Ctimes%20x%20%2B%203%20%3D%205%20%5Ctimes%2012%20%2B%203%20%3D%2063)
Answer:
3 students are eating lunches other than salads and sandwiches.
Step-by-step explanation:
To solve this you know that there are 18 students in the cafeteria and 1/6 of them are eating salads and 2/3 are eating sandwiches right? So you would have to think about what 1/6 of 18 is so you know how many students are eating salads, and 1/6 of 18 is 3 so there are 3 students eating salads. Now, you have to find out how many students are eating sandwiches, so you need to know what 2/3 of 18 is. 2/3 of 18 is 12 so now you also know that there are 12 students eating sandwiches. Next, you have to add 12 and 3 and you get 15. Since you know that there are 18 students in the cafeteria, you have to subtract 18 by 15, and you should get 3. So 3 students are eating lunches other than salads or sandwiches.
Hope this helps you! :D
