Hey there!
f.8=8f
0.8f = 8f
SUBTRACT 8f to BOTH SIDES
0.8f - 8f = 8f - 8f
SIMPLIFY IT!
-7.2f = 0
DIVIDE -7.2 to BOTH SIDES
-7.2f/-7.2 = 0/-7.2
CANCEL out3 -7.2/-7.2 because it give you 1
KEEP: 0/-7.2 because it help solve for the f-value
NEW EQUATION: f = 0/-7.2
SIMPLIFY IT!
f = 0
Therefore, your answer is: f = 0
Good luck on your assignment and enjoy your day!

Yes I believe that these are correct
Ouuuhhhh you smooth but the answer is negative 3 because that’s how I see yuu
This is how I did it:

use distribution

use addition

use addition and subtraction

use division


So your answer is
Answer:
20 seconds
Step-by-step explanation:
Your friend starts 10 meters in front of the starting line.
You start from the starting line.
You run at 6 meters/ second.
Your friend runs at 5.5 meters/second.
You and your friend will be at the same distance from the starting line only when you are able to catch your friend.
The relative speed between you two is the difference in your speed and your friend's speed that is:

So to cover 10 meters of separation at the speed of 0.5 meter/second it will take:

So it will take 20 seconds for you and your friend to be at the same distance from the starting line.
