Answer:
If 2 mph) 5 hours
If 2.5 mph) 4 hours
If m mph) 10/m hours
If m+2 mph) 10/(m+2) hours
If m/3 mph) 30/m hours
Step-by-step explanation:
To find the time divide the distance (10) by the speed.
10/2=5
10/2.5=4
10/m
10/(m+2)
10/(m/3)=10(3/m)=30/m
Since -3xy and negative 4xy are like terms, subtract 4xy from -3xy to get -7xy
-7xy is your answer
