The width of a bookshelf is four feet shorter than its height. Given that the width is 1.1 feet, write an equation that represents the height of the bookshelf.

It says that the width of the bookshelf is, so the width equals, four feet shorter than its height. That means we would need to take the height and then subtract four from it. Now we actually know that the width is 1.1 feet. So we can replace width with 1.1, and we can replace height with the variable ℎ, and bring down our minus four.

Therefore, ℎ minus four equals 1.1 would be an equation that represents the height of the bookshelf.
