Raymond has 120 books on his bookshelf that he has not read. He plans on reading 3 books per week until there are only 24 books

Oksi-84 [34.3K]

Answer: The correct option is (A) $120-3w=24;~32.$

Step-by-step explanation: Given that Raymond has 120 books on his bookshelf that he has not read. He plans on reading 3 books per week until there are only 24 books that he still needs to read.

We are to find the equation that can be used to determine the number of weeks it will take Raymond to have only 24 books left.

Also, we are to find the number of weeks.

The number of weeks it will take Raymond to have only 24 books left is represented by 'w'.

We have

number of books read by Raymond is 1 week = 3.

So, number of books read by Raymond is w weeks = 3w.

Since, there are total 120 books on his bookshelf, so the number of books left to read after w weeks will be

$120-3w.$

According to the given information, we get

$120-3w=24\\\\\Rightarrow 3w=120-24\\\\\Rightarrow 3w=96\\\\\Rightarrow w=32.$

thus, the required equation is $120-3w=24$ and number of weeks is 32.

Option (A) is correct.

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo

Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, number of words she can type = $\frac{90}{\frac{1}{60}}$

= 90×60

= 5400 words per hour

If she types $2.6\times 10^5$ words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= $5400\times x$

Therefore, $5400\times x =2.6\times 10^5$

$5400x=260000$

$x=\frac{260000}{5400}$

$x=48.15$ hours

Therefore, Dana types $2.6\times 10^5$ words in 48.15 hours.

What is the slope of the line passing through the points (0, 4) and (-8, -1)?

Bas_tet [7]

Answer:

0.625

Step-by-step explanation:

Given the points :

(0, 4) and (-8, -1)

x1 = 0 ; y1 = 4

x2 = - 8 ; y2 = - 1

Slope, m = rise / run

Rise = y2 - y1 = - 1 - 4 = - 5

Rise = x2 - x1 = - 8 - 0 = - 8

The slope, m = - 5 / - 8

Slope, m = 0.625

I forgot how to do this, can someone help me-

Artyom0805 [142]

Step-by-step explanation:

1) x/20 = -9

By cross multiplication,

x = -180

2) -168 = -14k

k = -168/-14

k = 12

3) -5m = -50

m = 10

4) -320 = -20n

n = 16

5) -4 = x - 5

x = 1

6) -6(-8 + n) = -54

42 - 6n = -54

-6n = -54 -52

6n = 106

n = 17.6

7) 3(x - 9) = -3

3x - 27 = -3

3x = 24

x = 8

8) 9k + 3 = -78

9k = -81

k = -9

9)4 + (n/4) = 8

By taking LCM,

16 + n/4 = 8

16 + n = 32

n = 16

10) -5r + 7 = -73

-5r = -80

r = 16

Hope it helps.
