The entrance fee to a fair is $12. Rides cost $4. The total cost, C, as a function of the number of rides, R, is given by C = 4R + 12

the answer would be B. R=C/4-12

Step-by-step explanation:

In order to find the total cost of the rides you would have to multiply the rides by their cost and then add on the entrance fee, however if you were to find the number of rides you would have to divide the total cost by 4 and then subtract 12 leaving the number of rides made.

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

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
