Answer 1

The correct choice is;

$7r\text{ = 84; r = 12}$

Here, we want to select the correct equation

From the question, she wants to plant 84 in rows of 7

So to know the number of rows, we can divide 84 by 7

Thus, we have this as;

$\begin{gathered} 7r\text{ = 84} \\ r\text{ = }\frac{84}{7}\text{ = 12} \end{gathered}$
