Emmy has already taken 44 quizzes during past quarters, and she expects to have 1 quiz during each week of this quarter. How many weeks of school will Emmy have to attend this
quarter before she will have taken a total of 47 quizzes?

(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 the answer is c.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
