Question

To stay healthy, Bella runs 7 kilometers every day.
Let d represent the number of days and k represent the total number of kilometers Bella runs.
Complete the table using the function k=7d.
d k
1
2
3 21
4

Answer 1

To complete the table using the function \( k = 7d \), we will plug in the values of \( d \) for each day into the equation to find \( k \).

1. For \( d = 1 \): \[ k = 7 \times 1 = 7 \]

2. For \( d = 2 \): \[ k = 7 \times 2 = 14 \]

3. For \( d = 3 \): \[ k = 7 \times 3 = 21 \quad \text{(already given)} \]

4. For \( d = 4 \): \[ k = 7 \times 4 = 28 \]

Now, we can fill in the table:

\[ \begin{array}{|c|c|} \hline d & k \ \hline 1 & 7 \ 2 & 14 \ 3 & 21 \ 4 & 28 \ \hline \end{array} \]

So the completed table is:

\[ \begin{array}{|c|c|} \hline d & k \ \hline 1 & 7 \ 2 & 14 \ 3 & 21 \ 4 & 28 \ \hline \end{array} \]
