y= -3x+2
Step-by-step explanation:

Answer:
y = 1/2
Step-by-step explanation:
Varies inversely
xy = k
------------------------
Find the constant of variation
y = 39 when x = 1/3
k = 1/3 * 39
k = 13
-----------------------
what is the value of y when x=26
26y = 13
y = 13/26
y = 1/2

Answer: x=20
Step-by-step explanation:
The entire thing is equal to 180 degrees. so, 100+3x+x=180, which can be simplified to 100+4x=180. If we subtract 100 from both sides, we get 4x=80, 80 divided by 4 is 20, so x=20
