Answer:
2. b
3. d
Step-by-step explanation:
I checked it based on the decimals. 5/8 = 0.625, which is B on the numberline in 2.
5/6 is 0.833, which is D on the numberline in 3
Answer:
The answer is 500
Step-by-step explanation:
500/10=50
Let x and (442-x) represent the distance of the trains traveled. X/90 mph=442-x/80 mph
Cross multiply 80×x =90(442-x)
80x=90×442-90x
170x=90×442
X= 90×442/170
X=234, distance traveled by train going 90mph
234mi/90mph = 2.6 hr, time it takes for the two trains tok meet.
Checking your answer:
90×2.6+80×2.6=234mi+208mi = 442mi
In the equation for a line, y=mx+b, you will find both the slope and the y-intercept. The letter m is your slope, and the letter b is your y-intercept. So, looking at your line's equation, we have y = 1/3x - 2. With this being said, 1/3 is your slope, and -2 is your y-intercept. Does this make sense?
