What the solution 2(4+2x)≥5x+5
olga nikolaevna [1]

Answer:

x ≤ 3

Step-by-step explanation:

2(4+2x) ≥ 5x+5      (by PEDMAS, expand parentheses first)

4(2) + 2x(2) ≥ 5x + 5

8 + 4x ≥ 5x + 5   (subtract 8 from each side)

4x ≥ 5x + 5  - 8

4x ≥ 5x - 3    (subtract 5x from both sides)

4x -5x ≥ - 3

-x  ≥ - 3  (multiply both sides by -1, remember to flip the inequality when multiplying both sides by a negative number)

x ≤ 3

5. The measure of an intercepted arc is 86, and the measure of the inscribed angle creating the intercepted arc is 3x +
Nonamiya [84]

Answer:

Th correct option is D. 13

Therefore the value of x is 13.

Step-by-step explanation:

Given:

measure of an intercepted arc = 86°

Center Angle = 86°

measure of the inscribed angle creating the intercepted arc= (3x+4)°

Angle Inscribed in arc = (3x+4)°

To Find:

value of x = ?

Solution:

Inscribed Angle Theorem:

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

\textrm{Angle Inscribed in arc}=\dfrac{1}{2}\textrm{Center Angle}

Substituting the values we get

3x+4=\dfrac{1}{2}86=43\\\\3x=39\\\\x=\dfrac{39}{3}=13\\\\x=13

Therefore the value of x is 13.
