5x + 2 = 2x - 10 solve for x

x = -4

Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side by subtracting 2x from both sides of the equation. That gives us 3x + 2 = -10.

Now we can move our numbers to the right by subtracting

2 from both sides and we get 3x = -12.

Now we can finish things off by dividing both sides by 3 and x = -4.

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
