What is the answer to a chef needs to cook 9 potatoes. he has already cooked 7.if each potato takes 3 minutes to cook, how long will it take him to cook the rest?

it will it take him 6 minutes to cook the rest.

Step-by-step explanation:

The chef needs to cook a total of 9 potatoes. He has already cooked 7 potatoes. That means that the number of uncooked potatoes left is total number of potatoes - number of cooked potatoes. It becomes

9-7 = 2 potatoes

If each potato takes 3 minutes to cook, this means that 2 potatoes will take 3 minutes × 2 j = 6 minutes

Since there are only 2 potatoes left uncooked, it will it take him 6 minutes to cook the rest.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
