If this was helpful, please mark it as brainliest! :D

the answer will be close to 50% so maybe like 48% or 49%

Step-by-step explanation:

The reasoning behind this is that the are 11 marbles total and half of 11 is 5 and a half. There are 5 red marbles which means that the chances are close 50% but because 5 isn't exactly half of 11 this means that your answer will need to be close to 50% but not exactly 50% which is why i gave the choices 49% or 48%.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
