Question

which of the following equations corresponds to the diagram below?
answer
$\boldsymbol{5z = 13}$
$\boldsymbol{z + z + z + z + z = 13}$
$\boldsymbol{z - 5 = 13}$
$\boldsymbol{5 + z = 13}$

Explanation:

Step1: Analyze the bar diagram

The total length of the bar is 13, which is split into two parts: 5 and $z$.

Step2: Relate parts to total

The sum of the two parts equals the total length.
<Expression>
$5 + z = 13$
</Expression>

Answer:

D. $5 + z = 13$
