Answer:

x + y + 90 = 180

x = 67

y = 23

Step-by-step explanation:

x + y + 90 = 180

x + 2 = 3y

x + y = 90

x - 3y = -2

x + y = 90

(+) -x + 3y = 2

-----------------------

4y = 92

y = 23

x + y = 90

x + 23 = 90

x = 67

Hip hop music makes up 75% of Landon's music library. If he has downloaded 120 hip hop songs, how many songs does Landon have in

Otrada [13]

Answer: 160 songs.

Step-by-step explanation:

75% hip hop music - 120 songs

100% all music - x songs

Let's write the proportion:

$\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160$

Thus, Landon have 160 songs in his music library.

Planes Q and R are parallel. Explain how you know lines a and b are skew.
