Janine bikes 4 mph faster than her sister, Jessica. Janine can ride 24 mi in 3 hr less time than Jessica can ride the same distance. Find each of their speeds.

Part 1 of 2

Jessica's speed is

Part 2 of 2

Janine's speed is

(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

answer: i wpould go with c
