Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
Letter A
because we should add the two smaller number in the radical and if the sum equals to the other one. Then, it is a right triangle

Answer:
It will take him <u>20 days</u> to read a 300-page book.
Step-by-step explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in =
days.
Thus, Stephen read 300 page in = ![\frac{6}{90} \times 300](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B90%7D%20%5Ctimes%20300)
![=\frac{1800}{90}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1800%7D%7B90%7D)
![=20\ days.](https://tex.z-dn.net/?f=%3D20%5C%20days.)
Therefore, it will take him 20 days to read a 300-page book.
