question
fill in the parts - whole model for the following equation.
$5x + 2z = (\underline{quadquad})$

Explanation:

Step1: Identify the parts and whole

The parts - whole model shows that the whole is the sum of its parts. Here, the parts are \(5x\) and \(2z\), so the whole (the expression on the left - hand side of the equation) is \(5x + 2z\), and the box should be filled with \(5x+2z\) as well (since the equation is \(5x + 2z=\text{(the whole)}\), and the parts are \(5x\) and \(2z\)).

Answer:

The top box (the whole) should be filled with \(5x + 2z\), and the equation is \(5x+2z=\boldsymbol{5x + 2z}\) (with the parts \(5x\) and \(2z\) as shown in the model).
