A woman bought some large frames for ​$13 each and some small frames for ​$5 each at a closeout sale. If she bought 12 frames for ​$​92, find how many of each type she bought.

4 of the large frame and 8 of the small frame.

Step-by-step explanation:

92= 13y+ 5x

4* 13= 52

8* 5= 40

40+52= 92

8+4=12

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

i got 10.28 but that rounds up to 10.3
