What is 1 and 5/6+1/2

  2 1/3

Step-by-step explanation:

Fractions are added using a common denominator.

  1 5/6 + 1/2

  = 1 5/6 + 3/6

  = 1 8/6

  = 1 + (1 2/6)

And they are reduced by removing a common factor from numerator and denominator.

  = 1 + 1 1/3

  = 2 1/3

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°
