A man drives 3 km east from home to the store and then 2 km west to a friend’s house. What is his displacement from his starting point at home?

1 kilometer east

Step-by-step explanation:

if you subtract 2 from 3 you get one, plus it's east with the bigger number, so that's why it's one kilometer east

40 minutes

step-by-step explanation:

add the time and multiply by 2

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
