Concrete building blocks weigh 28 pounds each. Using b for the number of concrete blocks and w for the weight, write two equations that relate the two variables. One equation should begin with \( w= \) and the other should begin with \( b= \).

Given that each concrete block weighs 28 pounds, and letting \( b \) represent the number of blocks and \( w \) represent the total weight, the relationships between these variables can be expressed with the following two equations: 1. **Equation starting with \( w = \):** \[ w = 28b \] *This equation states that the total weight \( w \) is equal to 28 pounds multiplied by the number of blocks \( b \).* 2. **Equation starting with \( b = \):** \[ b = \frac{w}{28} \] *This equation shows that the number of blocks \( b \) is equal to the total weight \( w \) divided by 28 pounds.* These equations allow you to calculate either the total weight based on the number of blocks or the number of blocks based on the total weight. **Summary of the Equations:** \[ w = 28b \] \[ b = \frac{w}{28} \]
