2. Marie-Renee wants to hang 4 identical posters on her wall. The wall is 16 feet wide, and there must be at least 5 feet of space total between the posters and between the edges of the wall. How wide can the posters be?
a) Marie-Renee write the inequality 4w + 5 ≤ 16 to help her plan. Match each statement below to describe what w, 4w, 5, and 16 represent in this inequality.
Draggable item
arrow_right_alt
Corresponding Item
the width of each poster
arrow_right_alt
w represents
the total amount of space between the posters and the edge of the wall
arrow_right_alt
4w represents
the width of the wall
arrow_right_alt
5 represents
the combined width of 4 posters
arrow_right_alt
16 represents
