An non-example of a independent variable is how much money you make selling cookies , because it depends on the number of cookies you sell .
Answer:
y = x + 5: x=y−5
2x + y = 17
: x=-1/2y+17/2
Step-by-step explanation:
I do not exactly know what you were asking but I just answered the questions, if that is not what you were looking for tell me so I can try and edit my answer
First, find the amount of time is taken to travel 1 mile :
time taken to travel 1 mile = 20/6 = 3 ⅓ mins
hence, time taken to travel 9 miles = 3 ⅓ x 9 = 30 mins
time taken to travel 10 miles = 3 ⅓ x 10 = 33 ⅓ mins
7 hours
steps:
10 1/2 divided by 1 1/2
Answer:
-2<x<9
Step-by-step explanation:
−21<−3x+6<12-21<-3x+6<12
Move all terms not containing xx from the center section of the inequality.

−27<−3x<6-27<-3x<6
Divide each term in the inequality by −3-3.
−27−3>−3x−3>6−3-27-3>-3x-3>6-3
Divide −27-27 by −3-3.
9>−3x−3>6−39>-3x-3>6-3
Cancel the common factor of −3-3.
Tap for more steps...
9>x>6−39>x>6-3
Divide 66 by −3-3.
9>x>−29>x>-2
Rewrite the interval so that the left value is less than the right value. This is the correct way to write an interval solution.
−2<x<9-2<x<9
The result can be shown in multiple forms.
Inequality Form:
−2<x<9-2<x<9
Interval Notation:
(−2,9)
