Jane has a gift card with a balance of 100$

100-10 = 15x

Step-by-step explanation:

You are subtracting 10 because that is how much is still left, its not included in the total spent.

15 represents the money spent per shirt, and x is the amount of shirts purchased

(Start-End)/Product Price= Products Purchased

6 T-shirts were purchased

Step-by-step explanation:

Jane Starts with $100

Buy's shirts $15 dollars each

Ends up with $10

Amount Spent = 100-10 = $90

T-shirts bought: 90/15 = 6

6 T shirts were purchased

Equation: (Start-End)/Product Price= Products Purchased

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
