1.) 7+7/9x=−42 2.) 4x+1=−15 3.)−4(x−3)=−40

Answers

Answer 1

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

   14/9x= = -42

  14/9x X 9x= -42 X 9x

    14= -378x

    -378x= 14

   -378x/-378= 14/-378

      x= -1/27

2) 4x+1=−15

 4x+1-1=-15-1

    4x=-16

   4x/4= -16/4

      x=-4

3) −4(x−3)=−40

 -4(x-3)/-4= -40/4

     x-3=10

   x-3+3=10+3

        x=13

[Help Please!] Find the value of x.

Answers

Answer:

x = 52

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles of a triangle

x+72 = 34+90

x +72 =124

Subtract 72 from each side

x = 124-72

x =52

Answer:

x = 52 degrees

Step-by-step explanation:

Let's first focus on the angle x + 72.  Immediately adjacent to x + 72 is angle RQS.  These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees.  Then angle RQS can be expressed as

180 degrees - (x + 72 degrees), or 108 - x degrees.

The three interior angles of the triangle must add up to 180 degrees.  Hence

108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:

108 - x + 34 = 90

This yields x = 52 degrees.

Can you plzz find the width...and give steps

Answers

The width will be 12 inches for Joy’s toy chest

Step 1. Find the volume of the Son’s chest:
(It is a rectangular prism) 30 x 16 x 24 =
11,520 cubic inches

I used the formula length x width x height.

Step 2. Make an equation to solve for the volume of the chest the daughter will have:
24 x 40 x w = 11,520 in2
11,520 because its said that the two chests should be teh same volume.

Step 3. Multiply the two dimensions of the daughters chest and divide it by the volume of the son’s chest:
11, 520/24 x 40 = 12
We divide it because we use the same formula for the volume of the rectangular prism, so to find the width, divide the length x height by the volume (this is proportionality)

Lets check it:
Volume of daughter’s chest:
12 x 40 x 24 = 11,520

Volume of Son’s chest:
30 x 16 x 24= 11,520

HAVE A NICE DAY

Answer:

12

Step-by-step explanation:

We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.

Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520

So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3

Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.

We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or

11,520/(40*24) = 11,520/960 = 12

Her chest is 12 inches wide

Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5

Answers

Answer:

C. y = 1/2x + 5

Step-by-step explanation:

For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.

For D. it doesn't even have x in it, so basically y equals a number.

C. is a linear equation, y = 1/2x + 5

The answer is C: y= 1/2 x +5

This is because any slope to a certain power would make it an exponential function.

C. y= 1/2 x + 5 is not to any power, making it linear

Kenna's bedroom is 12 feet long by 8 feet long. Her parents have agreed to buy new carpet for the entire bedroom.The carpet costs $15 per square meter. What will be the total cost of the new carpet? 1 foot = 0.305 meter

A. $439.20

B. $54.90

C. $133.96

D. $91.50

Answers

Answer:

C. $133.96

Step-by-step explanation:

Convert units:

12 · 0.305 = 3.66 m

8 · 0.305 = 2.44 m

Find the area of the room:

3.66 m · 2.44 m = 8.9304 m²

Find the cost:

8.9304 · 15 = 133.96

C. $133.96

12ft = 3.66 sq meters
8ft = 2.44 sq meters

3.66 x 2.44 = 8.9304

8.9304 x 15 = 133.956

B) the ore was deep underground. D) the ore was richest in the streams and rivers. C) the rock surrounding the ore was too hard for picks and hammers. Read the passage. Then answer the questions below.Philadelphia is a city known for many things. It is where the Declaration ofIndependence was signed in 1776, and it was also the first capital of the United States.But one fact about Philadelphia is not so well-known: it is home to nearly 3,000 muralspainted on the sides of homes and buildings around the city. In fact, it is said thatPhiladelphia has more murals than any other city in the world, with the exception ofRome. How did this come to be?More than 20 years ago, a New Jersey artist named Jane Golden started a programpairing troubled youth with artists to paint murals on a few buildings around the city.From this small project, something magical happened. The young people involvedhelped to create magnificent pieces of art, but there were other, perhaps more importantbenefits. The young people learned to collaborate and get along with many differentkinds of people during the various steps required to paint and design a mural. Theylearned to be responsible, because they needed to follow a schedule to make sure themurals were completed. They also learned to take pride in their community. It is hard forany resident to see the spectacular designs and not feel proud to be a part of Philadelphia.Take a walk around some of the poorest neighborhoods in Philadelphia,neighborhoods full of broken windows and littered front steps, and you will find beautifulworks of art on the sides and fronts of buildings. Of course the murals are not just in poorneighborhoods, but more affluent ones as well.Special buses take tourists to different parts of the city to see the various murals, whichrange from huge portraits of historical heroes, to cityscapes, to scenes depicting thediverse ethnic groups that call Philadelphia home.As a result of its success, the mural program created by Jane Golden has nowbecome the nations largest public art program and a model for other cities throughout thecountry seeking to help troubled youth.1Questions1) The main focus of the passage isA. an art program designed to help troubled youthB. the many tourists who come to Philadelphia to see muralsC. the reasons why Philadelphia is a unique cityD. how Jane Golden came up with the idea to start a mural program2) As used in paragraph1, the phrase it is said suggests that the author isA. knowingly misleading the readerB. using a quote from someone elseC. referring to something that is widely believed, but may be untrueD. referring to something that he or she does not personally believe3) As used in paragraph 1, the phrase with the exception of Rome means thatA.
