Answer:
the lcm would be 30 not 60
Step-by-step explanation:
Since the buses travel in opposite directions, the speed at which they distance themselves is the sum of their speeds.
One bus travels at speed s.
The other bus travels at speed s + 15.
The sum of the speeds is s + s + 15 = 2s + 15
speed = distance/time
distance = speed * time
366 = (2s + 15) * 2
183 = 2s + 15
168 = 2s
s = 84
The slower bus travels at 84 km/h.
s + 15 = 84 + 15 = 99
The faster bus travels at 99 km/h.
Check:
In 2 hours, the slower bus travels 2 * 84 km = 168 km
In 2 hours, the faster bus travels 2 * 99 km = 198 km
In 2 hours, the buses are 198 km + 168 km = 366 km apart.
Our answer is correct.
Answer:
D
Step-by-step explanation:
Negative means it goes down and if its linear then th line needs to be straight.
Answer:
1/2 or 0.5 (same value, different form)
Step-by-step explanation:
Ok...since I can't actually graph it, we can make a table out of it....
x y
7 -1
9 0
From -1 to 0, we add 1 (this is for the y section)
From 7 to 9, we add 2 (this is for the x section)
Now all we have to do is divide the y with the x
y/x = 1/2
The slope will be 1/2 (fraction form) 0.5 (decimal form)
Hope this helped!
Answer:
(5,9) and (5,3)
Step-by-step explanation:
Because the point is (5,6), and the question tells you to plot two points that are three units away from (5,6) but share the same X coordinate.
The X coordinate is 5. And 6 is the Y coordinate, if we do 6-3=2. 6+3=9.
