I think there might be a mistake/typo. If the book had 385 pages, the answer would be 8,855. But it says the book has 365 pages, so the answer would be 8,395.

Reasoning:

It says to multiply the pages by 23, and it says there are 365 pages. When you multiple that, you get 8,395.

Therefore I think there was a mistake when writing the question.

Explain why the equation 6|x| + 25 = 15 has no solution. When one solves, they arrive at a step where |x| is equal to a negative

LekaFEV [45]

Answer:

Step-by-step explanation:

Lets start solving until we get stuck,

6|x|+25=15

Subtract 25 from both sides

6|x|+25-25=15-25

Subtract

6|x|=-10

Divide both sides by 6

6|x|/6=-10/6

Divide

|x|=-10/6

We get stuck here, we need x to be negative but we cant have a negative x since we have absolute value. This means the answer is b.

HELPPP quick math question

emmasim [6.3K]

e^{-.15x}=.42

ln e^{-.15x}= ln (.42)

-.15x = ln(.42)

x = ln(.42)/-.15

x=5.78333718

OK so 1st you need to do 42 times .15 = 6.3 then you need to subtract that number from 42 which is 35.7 so that is your answer! I hope it helps :)

Debora drove 400 miles on her vacation. She drove an average of 1.5 times faster in the second 200 miles of her trip than she di

vodomira [7]

$t=\dfrac{s}{v}$
Time, she spent driving the first 200 miles:
$\dfrac{200}{x}$
Time, she spent driving the second 200 miles:
$\dfrac{200}{1.5\cdot x}$

Total time:
$\dfrac{200}{x}+\dfrac{200}{1.5\cdot x}=\dfrac{200}{x}\cdot \dfrac{1.5}{1.5}+\dfrac{200}{1.5\cdot x}=\dfrac{300}{1.5\cdot x}+\dfrac{200}{1.5\cdot x}=\dfrac{500}{1.5\cdot x}=\boxed{\dfrac{1000}{3\cdot x}}$
