it costs $12 for admission to the Fair, plus $0.50 for each ticket yo play games. if you have a total of $30 to spend, what is the greatest amount of tickets you can buy?

36 tickets

Step-by-step explanation:

First you set up your equation, which would be 12 + 0.50x = 30. Next you subtract 12 on both sides to get 0.50x = 18. Divide both sides by 0.50 to get x = 36.

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
