Need i will mrk brainliest! the variables y and x have a proportional relationship, and y = 12 when x = 5. what is the value of y when x = 8? enter your answer in the box. y=

y = kx for a proportional relationship

12 = k*5

divide each side by 5

12/5 = k

y = 12/5 x

if x=8

y = 12/5 * 8

y = 96/5

y = 19 1/5

step-by-step explanation:

sry but any answer choices

(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
