Which of the following number sentences is an example of the commutative property? Select all that apply. 1.9 × 1 = 1 × 1.9
14.7 + 2.8 = 2.8 + 14.7
2.5 × (3.4 × 1.4) = (2.5 × 3.4) × 1.4
4.5 × 5.5 = 12.375 × 2

(1.9 • 1 = 1 • 1.9; 14.7 + 2.8 = 2.8 + 14.7)

yes. we do proportions in probabilities.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
