Two classmates have decided to read all the volumes in a popular series of books. Rachel has
already read 4 volumes and will continue to read new ones at a rate of 2 volumes per week.
Rebecca, who hasn't started reading the series yet, will read 4 volumes per week. At some
point, Rebecca will catch up with Rachel and they will be reading the same book. How long
will that take?

your answer is the frist one

hop i

(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
