Answer:
x = 6
Step-by-step explanation:
Combine like terms here (anything with the same variable)
5x - 9x = -4x
6-2x = -4x+6
Add the lowest term in both sides
-2x + 4x = 2x
2x - 6 = 6
Add 6 to make 2x alone in order to get x
2x = 12
Divide both of the sides by 2 because that is how you get x all by itself
x = 6
Answer:
b) AC
Step-by-step explanation:
Exterior angle C is the sum of interior angles A and B. If angle A is 70, then angle B is 120-70 = 50. Angle C is the supplement of its exterior angle, so is 180-120 = 60.
The smallest angle is B, so the opposite side, AC, is the shortest side.

Answer:
Son's age = 24 years
Man's age = 48 years
Step-by-step explanation:
Let's take the age of son as x
Man's age = 2x
Twelve years ago,
Son's age= x-12
Man's age= 2x-12
Man is three times as old as his son so,
Solving for x,
2x-12(1) = x-12(3)
2x-12 = 3x-36
2x-3x = -36+12
-x = - 24
x = 24
So if we substitute the values we get,
Son's age = 24 years
Man's age = 48 years
Hope you understand :)
