Paolo is using number lines to find the value of the expression 1/6+ 2/3+ (-1 1/3).His first two steps are shown.

A. Draw an arrow on the number line provided to show the last step.

Step 1: Start at 1/6.

Step 2: Add 2/3.

Last step: Add (- 1 1/3)

B. What is the value of the expression 1/6+ 2/3+ (-1 1/3)?

(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

okay..i will pick 8!
