The answer is 3.75 or 3 3/4
Step-by-step explanation:
x = price per video game
y = price per CD
164 = 5x + 3y
and then we know
x = y + 12
now we can use this as substitute in the first equation :
164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60
104 = 8y
y = $13
x = y + 12 = 13 + 12 = $25
so, each CD costs $13.

Answer:
AAA (angle-angle-angle) similarity theorem
Step-by-step explanation:
The two given triangles PSR and XYZ, are similar.
And all their angles are also similar.
We can conclude, that both are similar based on AAA similarity theorem.
The AAA (angle-angle-angle) similarity theorem states that two triangles have their corresponding angles equal, if and only if their corresponding sides are proportional.
XZ is proportional to SR. XY is proportional to SP and YZ is proportional to PR.
