2y + 4 = 10
What is the first step in solving the
equation?

Its usually distribute or combine like terms but here we just solve.

Step-by-step explanation:

we do:

2y+ 4 = 10

   -4    -4

2y      6

---  =   ---

2         2

y = 3

the solution is h=10 because you add 9 to each side of the equation.

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
