what is there value of y?
what is the value of x?

Answers

Answer:

x=14

y=30

Step-by-step explanation:

5x+25=3x+53

5x=3x+28

2x=28

x=14

2y+35=95

2y=60

y=30

(I assumed all of the angles are equal, correct me if I'm wrong.)

Answer:x=14

Step-by-step explanation:

Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.

So, we will first start off by solving for x. We do this by using inverse operations.

5x+25=3x+53 We will subtract

5x=3x+28

2x=28 Divide

x=14

You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.

We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.

5(14)+25=95

180-95=85

85 is the value of 2y+35

We will solve for y just like any other alegrbaic problem

85=2y+35

50=2y

y=25

We know know that y is 25 and x is 14

Plug both values into 2 adjacent angles and they will add up to 180.

To print a telephone book,565 sheets of paper were used. If the book is 2.6 inches thick,what is the thickness of each sheet of paper.? Round to the nearest thousandth of an inch.

Answers

Using division, the thickness of each sheet of paper is 0.005 inches

What is the thickness of each sheet of paper?

To find the thickness of each sheet of paper, divide the total thickness of the telephone book by the number of sheets used.

Thickness of each sheet of paper = Total thickness / Number of sheets

Thickness of each sheet of paper = 2.6 inches / 565 sheets ≈ 0.004602 inches

Rounded to the nearest thousandth of an inch, the thickness of each sheet of paper is approximately 0.005 inches.

The telephone book is 2.6 inches thick, with 565 sheets of paper.

What this means is 2.6 inches is the thickness of 565 sheets of paper.

To find the thickness of each sheet of paper, all we do is:

2.6 ÷ 565

This gives us quite a large answer:

0.0046017699

To round to the thousandth place, we look at the third number past the decimal and look to see if we need to round up or round down.
The number to the right of our digit in the thousandth place lets us know (in this case) to round up.

Therefore, 0.0046017699 rounded to the nearest thousandth is:

0.005

Hello,

as 6^3=6*6*6=216
∛(-216)=-6
remember
∛(mn)=(∛m)(∛n)
and
if you have the 3rd root of a negative number, the root will be negative

∛-216=(∛216)(∛-1)
we know that 216=6^3 (you know, just fun fact)
6(∛-1)
3rd root of -1 is -1 ((-1)^3=-1)

Write the equation of a line that is parallel to the following:1. x = 5

2. y = -3

Answers

Answer:

1.  x=6

2.  y=2

Step-by-step explanation:

If x=5, the line is vertical, so we need a vertical line so that we are parallel.  A vertical line is x= a constant

We can choose the value for x as long as it is not 5, that would make it the same line.  I will choose x=6

If y=-3=5, the line is horizontal, so we need a horizontal line so that we are parallel.  A horizontal line is y= constant

We can choose the value for y as long as it is not -3, that would make it the same line.  I will choose y=2

Find the measure of the exterior angle.

Answers

Answer:

1) 128°

2) 126°

3) 108°

Question one:

   The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.  

38 + 90 + (180-x) = 180

38 + 90 + 180 - x = 180

38 + 90 + 180 - 180 - x = 0

38 + 90 + 180 - 180 = x

128 = x

Question two:

again, adding all the interior angles makes 180°. use this to make the equation.

3x + (5x-6) + 90 = 180

3x + 5x - 6 = 90

8x = 96

x = 12.

   x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,

180 - (5x-6) = the answer

180 - 5x + 6 = the answer

substitute x for 12

180 - 60 + 6 = the answer

126 = x

Question three

again, adding all the interior angles together makes 180°.

(a + 10) + 44 + (180-2a) = 180

a + 10 + 44 + 180 - 2a = 180

-a + 234 = 180

234 - 180 = a

54 = a

however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.

x = 108
