If demontra divided negative 100 by negative 2 and got negative 200 did why was the answer wrong and was anything done right?

Step-by-step explanation:

Demontra has to divide negative 100 by negative 2, which means she has to do:

This can be written as:

-1 / -1 = 1

Also, 100 / 2 = 50

So,

She got -200 which is wrong as she muliplied the numbers which is also wrong as -100 × -2 = 200

She did not done anything right.

step-by-step explanation:

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°
