I think it’s 0 bc it’s the only one that isn’t negative
Answer:
14.12 km
Step-by-step explanation:
Distance of Dawn = 6.42 km
Distance from Lin = 7.7 km in the opposite direction.
If they went in opposite directions then they were moving away from each other.
Therefore, the final distance between the two can be written as follows:
d = 6.42 + 7.7 = 14.12 km
After 20 minutes Dawn and Lin were 14.12 km away.
5(x-4x+5)=3-8x
5x-20x+25=3-8x
-15x+25=3-8x
-7x+25=3
-7x=-22
x= 22/7
Answer:
Step-by-step explanation:
average of x-coordinates = (-4+2)/2 = -1
average of y-coordinates = (11+3)/2 = 7
midpoint of AB = (-1,7)
Answer:
Step-by-step explanation:
10 hours - 2 hours 25 minutes - 3 hours 35 minutes
Lets just do this
2 hours 25 minutes + 3 hours 35 minutes
25 minutes + 35 minutes = 60 minutes
60 minutes = 1 hour
now we have 2 hours + 3 hours + 1 hour
2 + 3 +1 = 6
now we have 10 hours - 6 hours
10 - 6 is 4
4 hours.
