Answer:
I am I supposed to make a number line.
Step-by-step explanation:
It will take 8 minutes.
You use a proportion
5/1=2400/x you use 2400 because 2.4km=2400 meters and u need to use the same unit of measurement.
so cross multiplying gives you 5x=2400 which is equal to 480. BUT this is 48 seconds, and it asks you how many minutes, not seconds. So, you divide by 60 because there are 6 seconds in a minute, and you get 8.
Answer:
x=(-1/2) y=(3/2)
Step-by-step explanation:
y=x+2 Given
-3x=x+2 Substitute (-3x) for y
-2-3x=x Subtract 2 from both sides
-2=4x Add 3x to both sides
(-1/2)=x Divide both sides by 4.
y=x+2 Given
y=(-1/2)+2 Substitute (-1/2) for x
y=1 1/2
or
y=3/2
