The answer is, C
2x +3y=7.20
4x+2y=8.80
The first thing we must do for this case is to take into account the following variable:
x = speed in miles per hour
Then, by definition we have to:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values:
250 = x * 5
Answer:
An equation that can be used to find the speed of the train is:
250 = x * 5
Answer:
240 students
Step-by-step explanation:
28/35=x/300
cross multiply to get 35x=300*28
divide both sides by 35 to get 240
