Rosa wants to use $20 to buy games. The
inequality 2.50k + 5.50 < 20.00 represents the
number of games, k, she can buy with her money.
What is the greatest number of games Rosa can
buy?
A. 5
B.
6
C. 8
D.
10

The answer is B : 6

Step-by-step explanation:

2.50k means 2.50 multiplied by a number and the inequality means 20 is less than 2.50k + 5.50.    2.50 multiplied by 6 equals 15 and 15 plus 5.50 is 20.50 which is greater than 20.

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
