Tim's book has 50 pages. Lisa's book has 2 1/2 times as many pages.

Which shows how many pages (y) Lisa's book has?

125 pages

Step-by-step explanation:

If we times 50 by 2, we get 100. Then if we find half of 50, it's 25. We add them up, which we get the answer of 125 pages.

Hope this helps!

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
