The current temperature in Smalltown is 20 degrees Fahrenheit. This is 6 degrees less than twice the temperature that it was six hours ago. What was the temperature in Smalltown six hours ago? what is the algebraic equation ?
whats the variable?

(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

i believe it's a.

i'm not sure on this one, most likely correct.

the answer is c

step-by-step explanation: i took a test with this question on it
