Answer:
Step-by-step explanation:
2x - 3 is a linear expression. y = 2x - 3 is the equation describing y.
If x = 1, y = 2(1) - 3 = -1
If x = 2, y = 2(2) - 3 = 1
and so on.
Isn't there more to this problem that merely "2x - 3"?
Answer:
10 PM
Step-by-step explanation:
The combined speed of the two buses is ...
40 mph + 65 mph = 105 mi/h
The relationship between distance, speed, and time can be written ...
time = distance/speed
so the elapsed time until the buses cover the distance is ...
time = (1260 mi)/(105 mi/h) = 12 h
___
12 hours after 10 AM is 10 PM.
The buses will be 1260 miles apart at 10 PM.
Answer:
18 minutes to run a mile
Step-by-step explanation:
1.5 is equal to 150%. so given that you have 12 minutes you can do what is 150% to 12 so 100% of 12 is 12 and 50% of 12 is 6 and 6 + 12 is 18
