A person enters the room.
The mean age of the 6 people is now 24.
What is the age of the person who entered the room?

than do 23.50 times 18 and then divide your answer by 100 than you will get x.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
