Gavin is working two summer jobs, making $20 per hour lifeguarding and making $6 per hour walking dogs. In a given week, he can work no more than 10 total hours and
must earn at least $90. If z represents the number of hours lifeguarding and y
represents the number of hours walking dogs, write and solve a system of inequalities
graphically and determine one possible solution.

20z + 6y = 90

z + y = 10

Step-by-step explanation:

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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
