Let x and y represent the tens digit and ones digit of a two-digit number, respectively. The sum of the digits of a two-digit number is 9. If the digits are
reversed, the new number is 27 more than the original number. What is the
original number?

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°

it would rotate about 180 degrees.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
