Answer:
11*n
Step-by-step explanation:
11 is each bookshelf, n is an unknown number, try to imagine it as 2. You would multiply 11 by two to get total number of books.
Answer:
37 more than the quotient of 24 and 8 = 24 ÷ 8 + 37
Step-by-step explanation:
24 ÷ 8 + 37
Order of Operations
3 + 37
Add
= 40
The expression is 24 ÷ 8 + 37
Using proportions, it is found that Demarco needs 4 tiles.
----------------------
- This question is solved by proportions, using a rule of three.
- Each tile uses 1/2 = 0.5 ft.
- In total, he needs 2 ft.
Thus, the<u> rule of three</u> is given by:
1 tile - 0.5 ft
x tiles - 2 ft
Applying cross multiplication:
![0.5x = 2](https://tex.z-dn.net/?f=0.5x%20%3D%202)
![x = \frac{2}{0.5}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B2%7D%7B0.5%7D)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
Thus, Demarco needs 4 tiles.

Answer:
95
Step-by-step explanation:
We have been given a diagram triangle in which measurement of few angles in terms of x are given.
Using those we need to find the exterior angle but before that we need to find the value of x.
We know that exterior angle is equal to sum of two distant interior angles of that triangle so we can write:
(8x+15)=(3x+20)+(4x+5)
8x+15=3x+20+4x+5
8x+15=7x+25
8x-7x=25-15
x=10
Now plug x=10 into exterior angle 8x+15
8x+15=8*10+15=80+15=95
Hence final answer is 95.
