x^3 = 8/216

x^3 = (2^3/6^3)

(x^3)= (2/6)^3

x =2/6

x = 1/3

Solve the equation.<br><br>5/7=10/x+2​
skelet666 [1.2K]

Answer:

x=-\frac{70}{9}

Step-by-step explanation:

Isolate the variable by doing operations to both sides of the equation.  

The work is shown below:

\frac{5}{7} =\frac{10}{x} +2\\\\\frac{5}{7} - 2=\frac{10}{x} +2 - 2\\\\-\frac{9}{7} = \frac{10}{x}\\\\ -\frac{9}{7}*x = \frac{10}{x}*x\\\\ -\frac{9}{7}x = 10\\\\ -\frac{9}{7}x * (-\frac{7}{9})= 10 * (-\frac{7}{9}) \\\\x=-\frac{70}{9}

Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Amiraneli [1.4K]

Answer:

30

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the missing side

a^2 +b^2 = c^2  where a and b are the sides and c is the hypotenuse

x^2 + 40^2 = 50^2

x^2 +1600 = 2500

x^2 = 2500-1600

x^2 = 900

Take the square root of each side

sqrt(x^2) = sqrt(900)

x = 30

HELP PLEASE I NEED HELp
lidiya [134]

Answer:

Step-by-step explanation:

GH bisects ∠FGI

∠HGI = ∠HGF

4x - 14 = 3x - 3

4x = 3x - 3 + 14    {Add 14 to both sides}

4x = 3x + 11             {Subtract 3x from both sides}

4x - 3x = 11

x = 11

∠HGI = 4x - 14

         = 4*11 - 14

         = 44 - 14

         = 30°

∠FGI = 30 + 30

        = 60°

Find the solution of 5/2x - 7 = 3/4x + 14 <br><br> What is equal to x?
alexdok [17]

Answer:

Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.

Step-by-step explanation:

Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:

Groups: Not identified.

Exponents: Not identified, disparaging ₁.

Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21  <u>7x = 84</u>

Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>

Addition: Aggregate constants ⇒ 5/2x = 3/4x +21

Subtraction: Abate algebraic groups ⇒ 7/4x = 21
