Answer:
x=12
Step-by-step explanation:
4x+6y=60 y=2
4x+6(2)=60
4x+12=60
4x=60-12
4x=48
x=![\frac{48}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B48%7D%7B4%7D)
x=12
There are 3 movies. The total to rent all 3 is $13.20. To find the price of each movie, divide the total amount by 3.
Let M = amount per movie
M = (13.20)/3
M = $4.40
General rule: The angles on a straight line total 180°
The right angle equates to 90°
Since that angle is half of our desired angle, it must mean that 2x + x = 90°
breaking this down, we get 3x = 90° which can be divided to make x = 30°
