I believe the answer would be variable, because it is unknown which is very common for variables.
Plus, the variable definition (loose) is an unknown factor that can change in a trial.
I hope this helps!

Hi there! :)

4x + 5x + 12 = 6(x - 2)
Combine like terms and distribute the coefficient outside of the parenthesis:
9x + 12 = 6(x) + 6(-2)
9x + 12 = 6x - 12
Subtract 6x from both sides:
9x - 6x + 12 = 6x - 6x - 12
3x + 12 = -12
Subtract 12 from both sides:
3x + 12 - 12 = -12 - 12
3x = -24
Divide both sides by 3:
3x/3 = -24/3
x = -8.
1 real zero is the answer

How to solve such time related questions?
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time
Given:
- Speed = 5 1/2 miles per hour
- Time = 2 3/4 hours
Substituting it in the relationship we get,
Distance = Speed x Time
Distance = 5 1/2 miles per hour x 2 3/4 hours
Distance =
miles
Distance =
miles or 15
miles
Thus Judy travel's 15.125 miles or 15
miles in 2 3/4 hours
