Answer: The number of stickers she used to cover the length of the spine = 14.

Step-by-step explanation:

Given: The length of spine = [tex]10\dfrac12[/tex] inches  = [tex]\dfrac{21}{2}[/tex] inches

Length of each sticker = [tex]\dfrac34[/tex] inch

If she laid the stickers side by side without gaps or overlaps, the number of stickers she use to cover the length of the spine = [tex]\text{(Length of spine)}\div (\text{Length of each sticker})[/tex]

[tex]=\dfrac{21}{2}\div\dfrac{3}{4}\\\\=\dfrac{21}{2}\times\dfrac{4}{3}\\\\=\dfrac{7\times2}{1}=14[/tex]

The number of stickers she used to cover the length of the spine = 14.
