Which shows how to solve the equation -4/5 x = 80 for x in one step?
A. -4/5 (5/4) x = 80 (5/4)
B. -4/5 (-5/4) x = 80 (-5/4)
C. -4/5(-5) x = 80 (-5)
D. -4/5 (5) x = 80 (5)

answer:

step-by-step explanation:

(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
