It costs $3.25 for every pound of candy you buy
I can tell you that 5% of 45,000 is 2250! so i think the equation would be something like 45,000 + 2250x
Answer:
Step-by-step explanation:
Let x m/h be the speed of first bus.
Then speed of second bus=x-13 m/h
fist covers covers distance=3x
second covers the distance=3(x-13)=3x-39
again 3x+(3x-39)=339
6x=339+39=378
x=378/6=63
so speed of first bus=63 m/h
speed of second bus=63-13=50 m/h
Answer:
6(9+x)
Step-by-step explanation:
Answer: the rate of the passenger train is 100 mph.
Step-by-step explanation:
Let x represent the rate of the passenger train.
The rate of the freight train was 10 miles per hour slower than the rate of the passenger train. It means that the rate of the freight train is (x - 10) mph
The passenger train traveled 100 miles. It means that the time it took travel 100 miles is
100/x
In the same amount of time, it took a freight train to travel 90 miles. It means that the time it took travel 90 miles is
90/(x - 10)
Since the time is the same, then
100/x = 90/(x - 10)
Cross multiplying, it becomes
100(x - 10) = 90x
100x - 1000 = 90x
100x - 90x = 1000
10x = 1000
x = 100 mph
