solve for n: 14.23n - 15 = 41.92

Answers

Hopefully this helps
Answer: n = 4

Steps for Solving Linear Equation

14.23n−15=41.92

Add 15 to both sides.

14.23n=41.92+15

Add 41.92 and 15 to get 56.92.

14.23n=56.92

Divide both sides by 14.23.

n= [tex]\frac{56.92}{14.23}[/tex]

​Expand  [tex]\frac{56.92}{14.23}[/tex]  by multiplying both the numerator and the denominator by 100.

n= [tex]\frac{5692}{1423}[/tex]

Divide 5692 by 1423 to get 4.

n=4

Sam spent $1.08 to make 18 copies at office max.At that rate how much will he pay to make 40 copies?

Answers

Answer:

$2.40

Step-by-step explanation:

If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.

Chris types at an average speed of 45 words per minute. He has already typed 1,500 words of his final paper. The paper has to be more than 3,750 words. Which of the following inequalities could be used to solve for x, the number of minutes it will take Chris to finish his paper? ANSWER CHOICES R IN COMMENTS

Answers

Answer:

C. 45x + 1,500 > 3,750

Step-by-step explanation:

You know he has already started on his paper with 1,500 words and he needs to have more words than 3,750 in his final paper which includes the 1,500. Thus, he would have 45x number of words remaining in his paper, according to his speed of 45 words per minute.

Remaining words + 1,500 words must be more than 3,750.

45x + 1,500 > 3,750

The > sign means that something on the left is more than something on the right.

Answer:

C. 45x + 1,500 > 3,750

200 total action figures

Step-by-step explanation:

178 * 100 / 89 = 200

Answer: 200


Steps:

x(.89)=178

Divide both sides by .89 to isolate x

x=200

Check:


If you multiply 200 by .89 to find 89% of 200 you will get 178.

Answer:

A: I believe there is "Not enough information to determine". They could be emptying it to clean it, maybe something very toxic got spilled in, there's not enough information to determine the reason.
B:
Segment V: 0-2 hours      Desc.: Depth remains at a stable 7 ft.
Segment W: 2-6 hours     Desc.:  Depth declines from 7ft. to 5ft. at a rate of 0.5ft per hour.
Segment X: 6-8 hours      Desc.: Depth steadily drops from 5ft. to 0ft. at a rate of 2.5ft per hour
Segment Y: 8-14 hours     Desc.: Depth remains at 0ft.
Segment Z: 14-20 hours   Desc.: Depth rises from 0ft to 9ft at a steady rate of 1.5ft per hour.

Step-by-step explanation:

A: There is simply no explanation or answer given as to why they emptied the pool, and there are multiple reasons why they could've, so there isn't enough information to determine why the swimming pool was emptied and refilled.
B: Each line is straight. From 0 hours to 2 hours, the line is at 7ft, and it's horizontal, but it's also straight. Once the line goes diagonal, that's the end of that segment and the start of another. In order to get the rate per hour, you need to calculate the slope. y2-y1 over x2-x1.
