Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

A. 7(h-6k)^2
B. 7(h-18k)^2
C. 7(h-6k)(h+6k)
D. None of these

Answers

Answer:

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b² = (a + b)(a - b)

7h² - 252k² = 7(h² - 36k²)

= 7(h² - [6k]² )

= 7(h +6k)(h - 6k)

Lynn took a taxicab from the office to the airport. She paid $4 per mile plus a $6 flat fee. Her total cost was $66. How many miles was the trip?

Answers

Answer:

Step-by-step explanation:

Answer:

15 miles

Step-by-step explanation:

To answer this question, we must break up the question. First, we know Lynn paid a total of $66 for the trip. She had to pay $4 per mile, and the flat fee was $6, meaning that no matter how many miles they rode, she had to pay an extra $6 on top of that. So, we can subtract the total cost by the flat fee:

66 - 6 = 60

Then, we divide that number by the amount it costs to ride each mile, which is 4:

60 / 4 = 15

So, Lynn's trip was 15 miles

Hope this helps :)

Answers

Answer: 0.82 laps per minute

Step-by-step explanation:

Lin is running 21 laps in 25.6 minutes.

To find out her speed in laps per minute, divide the distance she has ran by the time it took her to run it.

A fisherman illegally drops some fish into a pond, and they quickly propagate (reproduce). The population
growth of the new specifies is modeled by P(x) =6(b)^x where x is the time in weeks following the moment
he dropped the fish into the pond and b is a positive unknown base. Suppose that b is 3. Graph this
relationship. How long does it take for there to be at least 100 fish in the pond?

Answers

Answer:

C. About 6 days

Step-by-step explanation:

Here the function that shows the population of fish after x weeks,

Where b is any unknown,

If b = 3,

Then, the function is,

Which is a exponentially increasing function,

That having y-intercept = (0,1)

And, horizontal asymptote,

y = 0

End behavior of the function:

As ,

Thus, by the above information we can graph the given relation.

Now, For at least 100 fish in the pound,

By taking log on both sides,

Thus, after 0.8567 weeks (approx) the fish on the pound will be at least 100.

1 week = 7 days,

0.8567 weeks = 5.9969 days ≈ 6 days

Hence, after 6 days (approx) the fish on the pound will be at least 100.

Write a short paragraph explaining how the text supports the idea that Fawcett was a remarkable man. Use at least two details from the text in your response.THE STORY 1 Since the dawn of the modern age, the notion of a pre-historic world, hidden deep in the jungle and untouched by the passage of time, has captivated our imaginations.2 Before Jurassic Park, before King Kong, there was The Lost World. Written in 1912 by Sherlock Holmes creator, Sir Arthur Conan Doyle, The Lost World was in turn largely inspired by the real-life adventures of one remarkable man: Col. Percy Harrison Fawcett.3 David Grann, a staff writer for The New Yorker magazine, says in his time Fawcett was a larger-than-life figure: Oh, he really was. I mean, he was the last of these kind of great territorial explorers who would plunge into the blank spots on the map, carrying a machete, essentially, and an almost divine sense of purpose.4 Grann was researching an article on Conan Doyle when he came across a reference to Fawcett.5 I had typed Fawcetts name into one of these newspaper databases, and up came all these kind of crazy headlines: Fawcett disappears into the unknown. A movie star kidnapped trying to save Fawcett.6 I had never heard of this man, and I quickly discovered there was this legendary figure, Grann said. And this enormous mystery that had been eclipsed by history. And it really intrigued me.7 So Grann started digging. Fawcett, he learned, was an honored member of Britains renowned Royal Geographical Society.8 He would live in the jungle for years at a time without contact with the world, Grann said. He discovered stories about how hed battle anacondas and electric eels, and how hed emerge with maps of regions that no one had ever came back from.9 In April 1925, Fawcett set out with just two othershis 21-year-old son Jack, and Jacks best friend, Raleigh Rimmelon what was to be his crowning adventure . . . finding the remains of a lost world he believed existed deep in the Amazon jungle of South America. 10 Fawcett called his mythical city, simply, Z. 11 After 30 years as an explorer, Fawcetts survival skills were unrivaled. But this time, he went in . . . and never came out. 12 Well, we know he got as far as a place called Dead Horse Camp, where he would send these dispatches back for five months, said Grann. And then after the fifth month, the dispatches ceased. And they were never heard from again. 13 . . . setting off one of the greatest manhunts of the 20th century. 14 George Dyott was the first, taking a film crew with him into the Amazon in 1928 and radioing back regular progress reports. 15 But he never found Fawcett. 16 In 1996 Brazilian financier James Lynch launched a multi-million dollar expedition to finally solve the mystery. But he and his party were kidnapped by tribesmen. 17 They were released only after surrendering $30,000 worth of gear. 18 Now, finally, after 85 years, the mystery that has tantalized so many may finally have been solved by perhaps Fawcetts least likely pursuer. 19 Grann turned his jungle adventure into a best-seller, The Lost City of Z, in which he recounts Fawcetts final days. 20 We stayed with many of the same tribes that Fawcett stayed with, said Grann. And to my astonishment, they had an oral history about Fawcett and his expedition. 21 It describes how Fawcett had insisted on moving eastward, towards the River of Death. And the tribe tried to persuade them not to go in that direction. In that direction were what they referred to as the fierce Indians. And off he marched. 22 And they could see the fire for five days, rising above the treetops. And then on the fifth day, it went out as if it was snuffed out. And they had no doubt that they had been killed by the Indians. 23 No physical trace of Fawcett has ever been found. But Granns efforts did bring one revelation to light: Fawcett may have been right about the lost civilization after all. 24 In the last few years, archaeologists are now going into this region using high-tech gadgetry that Fawcett could never imaginesatellite imagery, ground penetrating radars to pinpoint various artifacts, said Grann. And they are discovering ancient ruins scattered throughout the Amazon. 25 One archaeologist has found, in the very area where Fawcett believed he would find Z, 20 pre-Columbian settlements that had roads built at right angles, bridges, causeways, and that a cluster of these settlements that were interconnected had populations of between 2,500 to 5,000 people, which would have made them the size of many medieval European cities at the time.
