Number 3 and 4 please ASAP

Tpy6a [65]

Step-by-step explanation:

Question 3) there's 60 minutes in a hour

3 times 60 = 180 books in 1 hour

3 times 180 = 540 books in 3 hours

540 + 180 + 180 = 900 books in 5 hours

The difference between those numbers : 900-540= 360 and 540-180= 360 so every 2 hours 360 books is done each time so just add 360 books each time for every 2 hours added

Whatis the value of the expression<br> 2(x + 4) - (y-8)

valentina_108 [34]

Answer:

16 1/16

Step-by-step explanation:

x = ⅛
y = 3/16

= 2(x + 4) - (y - 8)

= 2(⅛ + 4) - (3/16 - 8)

= 2(4⅛) - (3/16 - 8/1)

= 2(33/8) - (3/16 - 128/16)

= (2 . 33/8) - (-125/16)

= 33/4 + 125/16

= 132/16 + 125/16

= 257/16

= 16 1/16

What is the answer to this question?

Lena [83]

Answer:

3x =6

x=2

Step-by-step explanation:

5x -2 = 4+2x

Subtract 2x from each side

5x-2x -2 = 4+2x-2x

3x-2 =4

Add 2 to each side

3x-2+2 = 4+2

3x =6

Divide each side by 3

3x/3 = 6/3

x = 2

HELP AGIAN PLEASEEEEEEEEEEEEEE

marusya05 [52]

Step-by-step explanation:

y=mx+b

6 -8

9 -7

$- 8 = 6m + b \\ - 7 = 9m + b \\ - 7 + 8 = 9m - 6m \\ 3m= 1 \\ m = \frac{1}{3} \\$

$- 8 = 6 \frac{1}{ 3} + b \\ b = - 8 - 2 \\ b = - 10 \\ y = 0.333x - 10 \\ y = \frac{x}{ 3 } - 10$
