Answer:

D

Step-by-step explanation:

yes it is.

start by multiply by 4 to get rid of the fraction on x

4 (\frac{x}{4}) = 4(4) + 4(\frac{2y}{3})

x = 16 + 8y/3

Then by 3 to get rid of that one

3(x) = 3(16) + 3(\frac{8y}{3})

3x = 48 + 8y

Then subtract 8y from both sides to get

3x - 8y = 48

Now given a rope hanging from the top of a pole. The end lying on the ground is 3 chi long. When tightly stretchedit is 8 chi fr
drek231 [11]

Answer:

Height of the pole = 9.17 chi.

Length of the rope = 12.17 chi.

Step-by-step explanation:

Given that the rope is hanging from the top of a pole having height x chi and the portion of the rope lying on the ground is 3 chi.

So, the length of the rope= x + 3 chi.

Let AB represents the pole in the figure, and one end of the rope is at point A.

When the rope is tightly stretched, let C be the other end of the rope as shown in the triangle.

The length of the rope = AC.

\Rightarrow AC=x+3 chi.

Distance from the bottom of the pole, point A, to the other end of the pole, point B, is 8 chi.

So, BC=8 chi.

As the triangle ABC is a right-angled triangle, so by using Pythagoras theorem,

AC^2= AB^2+BC^2

\Rightarrow (x+3)^2=x^2+8^2

\Rightarrow x^2+6x+9=x^2+64

\Rightarrow 6x=64-9=55

\Rightarrow x=55/6=9.17 chi.

Hence, the height of the pole, AB=x=9.17 chi,

and the length of the rope, x+3=9.17+3=12.17 chi.

Solve the inequality <br><br> −10 ≤ 2x - 4 &lt; 8
Roman55 [17]

Answer:

- 3 is greater than or equal to x is greater than or equal to 6

Step-by-step explanation:

- 10 \leq 2x - 4 \leq 8\\\\-10 + 4\leq 2x - 4 + 4\leq 8+4\\\\-6 \leq 2x \leq  12\\\\\\frac{-6}{2} \leq \frac{2x}{2} \leq \frac{12}{2}  \\\\-3 \leq x \leq 6

Hope this helps!!!!

HELP ASAP I HAVE TO GET IT DONE<br><br><br> Solve for x in the diagram below
MA_775_DIABLO [31]

Answer:

x = 35

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Geometry</u>

  • Definition of a Line: A line is 180°

Step-by-step explanation:

<u>Step 1: Set up equation</u>

40° + (2x + 30)° + 40° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    2x + 110 = 180
  2. Subtract 110 on both sides:         2x = 70
  3. Divide 2 on both sides:               x = 35

A circle has a diameter of 26 units. What is the area of the circle to the nearest hundredth of a square unit
Hitman42 [59]
To find the area of the circle, you will use the formula for finding area of any circle.

The radius is half the diameter.

A = pi x r^2
3.14 x 13^2
A = 530.66 square units

The area is 530.66 square units.
