Answer:
1.4 hour, or 1 hr 24 min
Step-by-step explanation:
The trains separate at the rate (80 + 90) mph.
Recall that distance = rate times time, or time = distance / rate.
238 mi
Here, the elapsed time is -------------- = 1.4 hr, or 1 hr 24 min
170 mph
50.24 bc a=3.14(radius to second power) and the radius would be 4, 4•4=16 and 16•3.14=50.24
Answer:
12 times 5=60 not 70
Step-by-step explanation:
12(5+2y)=4y-(5-9y
60+24y=4y-5-9y
60+24y=-5y-5
29y+60=-5
29y=-65
y=-65/29 or y= about -2.38

A cause 4 divide by 5 is .8 and 6 divide by 5 is 1.2
The equation of the line graphed below would be D. I can find two points that are easily distinguishable on this graph. (1, 5) and (0, 0). I found the slope by subtracting 0 from 5 giving me -5. Next, I subtracted 0 and 1 giving me -1. This gives me a fraction of -5/-1 which equals to 5.
