Answer:

n = -1

Step-by-step explanation:

First distribute the -4

15-4n+8=27

Combine 8 & 15

-4n+23=27

Subtract 23 from each side

-4n=4

Divide each side by -4

n=-1

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:

n= -1

Step-by-step explanation:

15-4(n-2)=27 do the () first

15-4n+8=27  subtract 15 and 8 from both sides to get the -4n alone

-4n= 4  divide by -4

a(q-8)=23

solve for q

help appreciated! ​

Answers

Answer:

q= (23+8a)/a

Step-by-step explanation:

a(q-8)=23

or, aq-8a = 23

or, aq = 23+8a

or, q = (23+8a)/a

(I’m not sure if the A is part of the question or if A is what question you’re answering but I’ll work o for both)

A(q - 8) = 23

Multiply everything inside the brackets by A:

aq- 8a = 23

Divide both sides by a to isolate q - 8a:

q - 8a = 23 / a

Add 8a to both sides to isolate q:

q = 23 + 8a² / a

Without the A:

q - 8 = 23

Add 8 to both sides to isolate q:

q = 31

Tyce hit 3/5 of the baseballs pitched to him during batting practice.Mason hit 3/4 of the number of the pitched that tyce hit. what fraction of pitches did mason hit?

Answers

Answer: 9/20

Step-by-step explanation:

From the question, we are informed that Tyce hit 3/5 of the baseballs pitched to him during batting practice and that Mason hit 3/4 of the number of the pitched that tyce hit.

The fraction of pitches that Mason hit will be gotten by multiplying 3/4 by 3/5 This will be:

= 3/4 × 3/5

= 9/20

Katie wants to buy a motor scooter that costs $518. She has already
saved $188 and will earn $22 each week from babysitting jobs. Write and
solve an equation to see how many weeks it will take Katie to save
enough money to buy the motor scooter.

Answers

Answer:

$518-$188 = $330

$330 ÷ $22= 15

It will take Katie 15 weeks to save enough money.

Answer:

It will take Katie 15 weeks to save up for her motor scooter.

Step-by-step explanation:

Step 1: Analyze Data

First, you can recognize that Katie is going to make $22 each week, making that our slope. She has already saved $188, so that is our y-intercept since it is our 'start amount.' And then we are given one more number, $518, which is our y value since it is our 'goal.'

Step 2: Create an equation

[tex]518=188+22x[/tex]

Step 3: Solve for x

[tex]518=188+22x\\330=22x\\x=15[/tex]

the number y of calories burned after x hours of rock climbing is represented by the linear function y=650x find the domain , is the domain descents or continuous? explain

Answers

Answer:

The domain is discrete

Step-by-step explanation:

Given

[tex]y = 650x[/tex]

Required

What type of domain is it?

Based on the given options, the domain is continuous.

From the question, we understand that x represents the hours spent in climbing the rock.

The climber can decide to climb for 1 hour, 2 hours, ½ hour, ⅓ hour, ¼ hour, etc..

A domain is said to be discrete if it can only take integers (i.e. whole numbers), if otherwise, it is continuous;

So, since x is not limited to only whole numbers, then we can conclude that the domain of x is continuous

Help ??? :)The Mystery of Loch NessBy Kayden MitchellOf all the mysteries in the world, none has been as popular as that of the Loch Ness Monster. Perhaps the biggest mystery is whether it is convincing evidence or a simple desire to believe that keeps the myth alive.Loch Ness is a lake in Scotland. The loch, or lake, is known for sightings of a mysterious monster. Most who see this monster, known as Nessie, describe something with a long neck and several humps above the water. Sometimes the "monster" is moving in these sightings, and sometimes it is still. Many have suggested that Nessie might be a plesiosaur (plea-see-a-soar), an aquatic dinosaur that was trapped in the loch after the last ice age.The plesiosaur theory presents several problems. First, the plesiosaur is an air breather. Such a creature would need to surface often and, therefore, be seen more frequently. Second, it's unlikely that the same creature has lived in the loch since the last ice age. Today's creature would have to be the offspring of an original plesiosaur trapped long ago. This would suggest multiple creatures in the loch (needed to produce offspring). Again, sightings would be more frequent if this were the case.So from a purely logical stand point, the existence of such a large and ancient creature is unlikely. But assume for a minute that it is possible. What would a plesiosaur need to live in an enclosed lake?Tropical waters: Scientists believe plesiosaurs were warm-blooded. Like crocodiles and alligators, plesiosaurs would need to live in warm waters. The loch is very cold with temperatures averaging about 40 degrees Fahrenheit (4.4 Celsius).Food: Like other warm-blooded creatures, plesiosaurs would need a large quantity of food. If there is a group of Nessies, then even more food would be needed. Because the loch is full of silt (underwater dust) not much light gets into the deepest areas. So the food chain, which would depend on plankton, is very weak at its base. As a result, there is probably not enough food to support such a large creature.However, the plesiosaur theory is not the only one. Many other ideas attempt to explain the sightings and "photographs." But two separate sonar surveys of the loch have not found any evidence of a creature larger than a salmon. The last survey1, completed in 2007 by the British Broadcasting Company (BBC), involved 600 different sonar beams. Using satellite navigation systems, the team made sure every inch of the loch was searched. The team found nothing.With cell phones and digital cameras, one would think that sightings of Nessie would increase. This has not happened. The BBC team believes the legend of Nessie has endured because people see what they want to see. To prove this, the team used a fence post, raising it before groups of tourists. Afterwards several of the tourists asked to draw pictures of what they had seen drew pictures of a monster's head.1 "BBC 'proves' Nessie does not exist." 27 July, 2003.Which describes the introduction to the essay?
