Zoe gives 7 shells to Dev, leaving her with 48. Dev then has 16 shells in total. Step-by-step explanation: Denote the initial shell count for Dev as A and Zoe’s as B. Based on the scenario where Zoe transfers x shells to Dev while then possessing three times the number of shells relative to him, the resulting references show that Zoe provided 7 shells, leaving her count at 48 while Dev's total became 16.
If rational roots exist, they would be factors of the constant term (9) over factors of the leading coefficient (12).
The formula representing this scenario is 
The answer to this formula is 
Initially, you need to formulate the equation.

Next, simplify the expressions.

Afterwards, subtract 5.7 from both sides.

Lastly, divide both sides by 5

In a pictorial graph, icons are utilized to depict the data presented. For instance, if a survey was conducted regarding food preferences at a barbecue, we might incorporate images of a hamburger, a hot dog, and a chicken leg. However, we cannot deduce the quantities involved merely by juxtaposing the icons.
