What is the value for y?
goldenfox [79]

Answer:

x=39

y=28

Step-by-step explanation:

this is isosceles triangle

from the picture

angle A equals to angle B

so

34=x-5

39=x

so A and B are 34 degree each

so angle C is 180-2(34)

then 180-2(34)=4y

180-68=4y

112=4y

28=y

The garden view hotel is seventeen less than twice the height of the plaza hotel. If their combined height is 361 feet, how tall
lisov135 [29]

The garden view hotel is 235 feet tall

Step-by-step explanation:

The given is:

  • The garden view hotel is seventeen less than twice the height of the plaza hotel
  • Their combined height is 361 feet

We need to find the height of the garden view hotel

Assume that the height of garden view hotel is x feet and the height of the plaza hotel is y feet

∵ The height of the garden view hotel = x feet

∵ The height of the plaza hotel = y feet

∵ The height of the garden view hotel is 17 less than twice the

    height of the plaza hotel

- That means x is less than 2 × y by 17, equate x by the difference

   of 2 × y and 17

∴ x = 2y - 17 ⇒ (1)

∵ Their combined height = 361 feet

∴ x + y = 361

- Find y in terms of x by subtraction x from both sides

∴ y = 361 - x ⇒ (2)

Substitute y in equation (1) by equation (2)

∵ x = 2(361 - x) - 17

- Simplify the right hand side

∴ x = 722 - 2x - 17

- Add like terms

∴ x = 705 - 2x

- Add 2x to both sides

∴ 3x = 705

- Divide both sides by 3

∴ x = 235

The garden view hotel is 235 feet tall

Which number line correctly shows the location or approximate location of the three numbers?
GREYUIT [131]
<h2>Hello!</h2>

The answer is: D. is the fourth picture.

<h2>Why?</h2>

First, we need to make these numbers entire or decimal numbers, in order to see where are they located:

2\sqrt{5} =4.47\\\frac{6}{7}*\pi =2.69\\\sqrt{16} =4

So, we should look for the image that shows the following order it: 2.69, 4 and 4.47

or

\frac{6}{7} *\pi

\sqrt{16} =4

2\sqrt{5}

Then, we just need to find the image where they are properly located/ordered:

So, the correct image is D. is the fourth picture.

Have a nice day!
