Answer:
3 x + 14
Step-by-step explanation:
Simplify the following:
6 x - 3 x - 11 + 25
Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):
(6 x - 3 x) + (-11 + 25)
6 x - 3 x = 3 x:
3 x + (-11 + 25)
25 - 11 = 14:
Answer: 3 x + 14
Answer:
1.4 hour, or 1 hr 24 min
Step-by-step explanation:
The trains separate at the rate (80 + 90) mph.

Here, the elapsed time is -------------- = 1.4 hr, or 1 hr 24 min
170 mph
X = 10 - y
I hope this helps.:)
