Ms. Pryce has 82 books. She puts 10 of them in her desk. The rest will go in her bookcases.
One bookcase has 2 shelves, and the other has 4 shelves. Write and solve an equation to find
s, the number of books Ms. Pryce should put on each shelf so that each has the same
number of books.

12 books per shelf

Step-by-step explanation:

She has 82 books and ten of them go to her desk. So she has 72 books left to to put on her shelves. There are a total of 6 selves.

So (72 books) / (6 shelves) = 12 books per shelves.

General equation:

{(total number of books) - (books go to her desk) ] / (total number of shelves)

s = number of books on shelves

t = total number of books

d = books on desk

x = number of selves

s = (t-d) / x

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
