Josephine wants to put wallpaper border around the ceiling. the lenth of the border is 8 and 1/2 and the wisthn is 10 and 9/12. what is the perimeter.

Assuming the ceiling has a rectangular shape, the perimeter is the sum of the lengths of all the sides, hence twice the sum of length and width.

2(8 1/2 + 10 9/12) = 2(18 +6/12 +9/12)

= 2(18 +15/12)

= 2(19 3/12)

= 2(19 1/4)

= 38 1/2 . . . . . the room's perimeter

is should be y = 5x

step-by-step explanation:

correct me if im wrong

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
