2 (3x - 5) + 4 = -18


Solve for 20 Points

Answers

Answer:

x = -2

Step-by-step explanation:

2(3x - 5) + 4 = -18

Distribute the 2

6x - 10 + 4 = -18

6x - 6 = -18

Add 6 to both sides

6x = -12

Divide both sides by 6

x = -2

Check:

2(3x - 5) + 4 = -18

substitute x = -2 into the original equation

2(3(-2) - 5) + 4 = -18

2(-6 - 5) + 4 = -18

2(-11) + 4 = -18

-22 + 4 = -18

-18 = -18

So x = -2 is true.

Answer:

x=-2

Step-by-step explanation:

2(3x-5)+4=-18

We move all terms to the left:

2(3x-5)+4-(-18)=0

We add all the numbers together, and all the variables

2(3x-5)+22=0

We multiply parentheses

6x-10+22=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place

Answers

Step-by-step explanation:

I think you have forgotten to attach the question.

Anyways....

In order to find the area of a circle use the formula:

π[tex]r^{2}[/tex]   Where r is the radius

For example the radius is 3cm. The area of the circle will be:

π × [tex]3^{2}[/tex]

Since you have taken pi as 3.142...

3.142 × [tex]3^{2}[/tex]

3.142  × 9

= 28.278

In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.

Two brothers went shopping at a back-to-school sale where all shirts were the same price, and all the shorts too. The younger brother spent $230 on 8 new shirts and 10 pairs of shorts. The older brother purchased 8 new shirts and 4 pairs of shorts and paid a total of $116. How much did each item cost?

Answers

Answer:

Younger: 12.78 per item

Older: 9.67 per item

Step-by-step explanation:

Well, if all the shirts and shorts were the same price divide the total price and total amount of items they bought.

Younger Brother:

8 shirts + 10 shorts = 18 items for $230

$230 ÷ 18 items = about 12.78 per item (it comes out to a lot of number so I estimated it the nearest hundredth)

Older Brother:

8 shirts + 4 shorts = 12 items

$116 ÷ 12 items = about 9.67 per item (estimated again)

If there are two children in the Patel family. They are twins of the same age. Then zero is  the range of their ages

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

There are two children in the Patel family.

They are twins of the same age.

Let x be the age of two children.

As they are twins so the age of children's is same.

The formula of range is highest minus lowest.

range = highest - lowest

Range=x - x

Range =0

Hence, the range of their ages is 0.

Minutes Hours

Answers

Ok so first we need to under stand that 60 minutes is equivalent to 1 hour, by knowing this we should be able to answer the following. Our first box which needs to be filled in asking how many hours are in 300 minutes, well let’s figure this out. So we know that in 60 minutes it will be equivalent to one hours, so in order to find how many minutes are in 300 minutes we would divide 300 by 60 which give a us 5. Therefore causing the second box to me 5 hours. Our next and final box is asking how many hours are in four minutes well this one is a little harder than our previous one but I’ll help you through it. By following the same procedure as we did the previous question we are going to divide 4 by 60 and we know that dividing like so we are going to get a decimal but that’s ok it’s going to give us the answer we need to fill in the box. By dividing like so we should get a long decimal that look that this 0.066666666666667. I am going to simply this down to 0.0667. Causing my last box to be 0.667.
Summary:
second box: 5 hours
Third box: 0.0667 hours

Find the area of the circle, given the square has an area of 144 cm2 (leave your answer in terms of ).
A)
127 cm?
B)
2471 cm2
C)
3671 cm2
D)
7271 cm2

Answers

C is the answer to this question explanation: Area of square = 144 cm2, which means each side is √144 = 12 cm

Since the circle is inscribed in the square, the diameter is 12, so the radius is 6cm.

Area of circle = πr2 = π * 62 = 36π cm2, which is your answer :)

Work out who saves the most of their salary each month.
You must show how you get your answer.

Answers

Answer:

isabel saves the most of their salary each month

Step-by-step explanation:

Let us assume the Salary of Gavin, Harry & Isabel be $100

Since

Gavin saves 28%

So his saving amount is Gavin

= 28% of $100

= $28

As harry spends 3 ÷ 4 of his salary

So Harry Spenings is

= (3  ÷ 4) of $100

= $75

Now

Harry Saving is

= $100 - $75  

= $25

Also the ratio between isabel saves, and spend is 3:7

3k + 7k = 10k = 100S

 k = $10

Now

the amount of salary isabel saves

= 3k

= 3 × $10

= $30

Now

$30 > $28 > $25

i.e.

isabel Saving >  Gavin Savings > Harry Savings

Hence, isabel saves the most of their salary each month

"You're letting them control you!" they say. "They aren't that bad! You're making it up for attention!"Addie and Ziah dig their claws in a little deeper every time they hear that.When I tell people about Addie and Ziah, how they hurt me, they tell me to just try not to listen. "Don't listen to them! Be happy! If you think positively, they'll go away."They've taken all my happy thoughts. Ziah feeds on them, spitting them back out as poison that Addie then spreads like a disease until there's nothing left.Ziah whispers in my ear, telling me how terrifying the world is, how everyone hates me, how everyone judges me, how I'm messing up, how I'm a waste of space and air, how I should just give up. She reminds me of how fragile I am, how easy it would be to draw blood, how easy it would be to give up.Addie is less subtle, choosing to scream rather than whisper.She isn't as nice, either. Ziah is only telling the truth, but Addie tells me anything she thinks of.What if you put your finger in an electric socket? she screams. What if you chewed your fingers until they bled? What if you went a little too far while wrestling with your siblings? What if you threw something across the room?What if you died?Sometimes they work in harmony, screaming and whispering at the same time, telling me I'm not enough so I should hit something, telling me I'm worthless so I should distance myself from everyone, telling me I should just... stop.Addie doesn't stop at screaming in my ear, though. She's in my whole body, in my legs to make them constantly bounce and annoy people (Ziah loves that, she tells me everyone hates me because I'm constantly moving). She's in my chest, squeezing my heart and lungs and filling them with electricity until I feel like I have to burst (Ziah does this too, except when she does it hurts more). She's in my brain, stealing my memories and thoughts and setting fire to my emotions.Fire. That's a good way to describe what Addie does to me. She sets fire to my skin, making it crawl with energy until I feel like it's going to break through and I'm going to die. She sets fire to my thoughts and memories until they burn up and I can't find them anymore. She sets fire to my emotions, making them burn too brightly and too hot until I burn other people with them.Full would be another good way. I'm full of energy and emotion and it makes me feel sick and pressured and I need to do something, anything to release the pressure, and sometimes I feel as though knives are the only option~They aren't, though. Haven't been for almost a year now. Addie and Ziah have given me that much.Nobody blames the demons, though. They blame me."Why can't you sit still? Why can't you be quiet? Why can't you remember? Why can't you pay attention? Why are you so annoying?It's the demons!I need a review of Don't listen"Don't listen to them, then!" I have no thoughts of my own to listen to instead. I have no name.
