Final answer:
To complete a bar diagram using the given numbers of pictures taken by Adam and Tessa, compare the number of pictures taken by each person and create rectangular bars proportional to the number of pictures taken.
Step-by-step explanation:
The problem asks us to complete a bar diagram using the given numbers of pictures taken by Adam and Tessa. To do this, we need to compare the number of pictures taken by Adam and Tessa. Adam took 19 pictures and Tessa took 92 pictures.
To create a bar diagram, we can use rectangular bars to represent the number of pictures taken by each person. The length of each bar will be proportional to the number of pictures taken. In this case, the bar for Adam would be much shorter than the bar for Tessa.
We can represent this information using an equation:
x = Number of pictures taken by Adam
y = Number of pictures taken by Tessa
Based on the given information, we can write the equation as:
x = 19
y = 92
