60t +60 = 80t
subtract 60t from both sides of=
20t = 60
t = 3
The two trains are the same distance from Chicago at 3pm, at that time both trains will have covered 240 miles
Answer:
B (2,8)
Step-by-step explanation:
Answer:
9x - 3
Step-by-step explanation:
Hello!
A square has 4 sides.
We can factor out 4 from the expression to find the value of one side.
Factor:
- 36x - 12
- 4(9x) - 4(3)
- 4(9x - 3)
This means that each side of the square is 9x - 3 units long.
The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore,
increasing the average cost of gas from $1.50 to $2.20 will increases
the steepness of the line. (i.e. the line becomes closer to the vertical
line).
