Answer:
Option A
Step-by-step explanation:
Jessica divides the ribbon in three parts out of which length of one part = [tex]3\frac{1}{2}[/tex] inches
Let the length of other two parts = x inches
Total length of whole ribbon = 12 inches
[tex]3\frac{1}{2}+x+x=12[/tex]
[tex]3\frac{1}{2}+2x=12[/tex]
[tex]2x=12-3\frac{1}{2}[/tex]
[tex]2x=12-\frac{7}{2}[/tex]
[tex]2x=\frac{24-7}{2}[/tex]
[tex]2x=\frac{17}{2}[/tex]
[tex]x=\frac{17}{4}[/tex]
[tex]x=7\frac{1}{4}[/tex] inches
Therefore, option A will be the answer.
