Cara is hanging a poster that is 91 centimeters wide in her room. the center of the wall is 180 cm from the right end of the wall. if cara hangs the poster so that the center of the poster is located at the center of the wall, how far will the left and right edges of the poster be from the right end of the wall?

The left edge of the poster will be 225.5 cm from the right edge of the wall and the right edge of the poster will be 134.5 cm from the right edge of the wall.

Step-by-step explanation:

The poster is 91 cm wide.  This means that the center of it will be 91/2 = 45.5 cm from each edge of the poster.

Since the center of the poster is now 180 cm from the right edge of the wall, this makes the right edge of the poster 180-45.5 = 134.5 cm from the right edge of the wall.

The left edge of the poster will be 180+45.5 = 225.5 cm from the right edge of the wall.
