Michael spends 3 hours cleaning his house. He spends equal amounts of time cleaning each room. If he spends 1/2 hour cleaning each room, how many rooms does his house have

6 rooms

Step-by-step explanation:

3 hours= 60min*3= 180 min

180/30 min each room= 6 rooms

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
