Question

You are redecorating your bedroom and want to place two posters on the wall. Your wall is 12 feet, 6 inches long and each poster is 27 inches across. You want to make sure that the distance in between posters and the distance from each poster to the walls is equal. Your brother thinks you should place the posters about 30 inches from the wall. Is your brother's estimate reasonable?

Answer 1

Answer:

1 ft = 12 in

14 ft = 14*12 in

14 ft = 168 in

Now we can write the following equation:

3x + 2*42 = 168 + 3

........

........

x = 29 in

The poster should be placed 29 inches from the edge of the wall.
