Answer:

The answer I got was 86.

Step-by-step explanation:

This is called the central angle theorem. This means that the central angle, which in this case is QOR (let the origin (middle) be O), is twice the size of the inscribed angle, which is QPR.

That means: 2 x QPR = QOR

→ 2 * (x-33) = x + 20

→ 2x - 66 = x + 20

Collect the like terms

→ 2x - x = 20 + 66

x = 86

The absolute value of -4 ( |-4| ) is 4.

These numbers should go in this order:

-10 < 0.121212... < $\pi$ < |-4| < $5\frac{1}{2}$

2(2x + 3) = -6(x + 9)

sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.
