There were 84 people on the train 43 people got out then 61 people went on the train and 22 people got off the train. how many people are on the train now ?

80 people are left on the train.

Step-by-step explanation:There was 84 people but then 43 left so you subtract 84-43 which equals 41. 61 people got in so you add 41+61 which equals 102.Then 22 get off ao you subtract 102-22 which equals 80.

First you take the 84 people on the train and subtract it by 43 getting the answer of 41. Since 61 people entered the train after 43 got off, you add 61 + 41 to get 102. Lastly, you then subtract 22 from 102 to get 80.

Therefore, there are 80 people left on the train.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
