Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1
Answer:
9/4 cups
Step-by-step explanation:
6 3/4 = 27/4
27/4 * 1/3 = 27/12
27/12 = 9/4
Answer
y=−3/5x−23/5
given the slope m of a line then the slope of a line
perpendicular to it is
Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed

2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer
