Answer:
4/42, I think, tell me if im wrong
Step-by-step explanation:
Direct variation can be written as a proportion. Therefore, we can write:

Cross multiply to get:
4y=40
Divide by 4 on both sides to get that

Answer: son is 12 years old
Step-by-step explanation:
Let m be the age of mother, f be the age of father, and s be the age of son.
m + f + s = 28 x 3 = 84
m + son = 23 x 2 = 46
f + s = 25 x 2 = 50
m = 46 - s
f = 50 - s
we plug in m and f to the functions.
we get 46 - s + 50 - s + s = 84
96 - s = 84
-s = -12
s = 12 years old
Let the second angle be x.
Second angle = x
First angle = 3x - 6
The sum of the two angles is 180°
x + 3x - 6 = 180
4x - 6 = 180
4x = 186
x = 186 ÷ 4 = 46.5°
Second angle = 46.5°
First angle = 3(46.5) - 6 = 133.5°
Answer: The angles are 46.5° and 133.5°
