Answer: B. 
Step-by-step explanation:
The notation to express a dependent variable is given by :-
, where Y is depending variable which is dependent upon x ( independent variable).
The given statement : The distance an airplane travels depends on how much time it spends flying.
Here , Independent variable : Time
Dependent variable : Distance
Then , the notation to express distance (dependent variable) the airplane flies in 20 minutes is given by :-

X = Dimes Y = Nickels
x + y = 175
.10x + .05y = 13.30
The answer would be D. because there seven family plus same amount they have
Answer:
n =7 or n = -17/3
Step-by-step explanation:
10 - |3n - 2| = -9 (subtract 10 from both sides)
- |3n - 2| = -9 - 10
- |3n - 2| = -19 (multiply both sides by -1)
|3n - 2| = 19
(3n - 2) = 19 or (3n - 2) = -19
For (3n - 2) = 19,
3n - 2 = 19
3n = 21
n =7 (answer)
For (3n - 2) = -19,
3n - 2 = -19
3n = -17
n = -17/3 (answer)
