30 Points Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?

The answer is four months

Step-by-step explanation:

You have a starting cost of $50 with a $20 fee every month

OR

You have a starting cost of $30 with a $25 fee every month

Start: $50 ($20 per month)

M1 = $70, M2 = $90, M3 = $110, M4 = $130

Start: $30 ($25 per month)

M1 = $55, M2 = $80, M3 = $105, M4 = $130

In conclusion, the prices of the two will match at Month 4

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
