Answer:

1. the weight of a bag of beans in the box
2. B, C, E

Explanation:

1. In the description, we are given the weights of the box and of the rice precisely. The weight of the beans is described as 15 bags. When we see the equation, we see that it has specific numbers for the weights of the empty box, the rice, and the full box. The weight of beans is represented by the term 15b. We know there are 15 bags, so we presume the b represents the weight of one bag of beans.

2. One way to tell if the equations are equivalent is to simplify them all to the same form. Here, that can be p·b = q.

Given equation: subtract 4.6: 15b = 21

A: subtract 4: 15b = 21.6 . . . not equivalent

B: subtract 4: 15b = 21 . . . . . equivalent equation

C: divide by 3, subtract 4.6: 15b = 21 . . . equivalent equation

D: as is: 15b = 25.6 . . . not equivalent

E: as is: 15b = 21 . . . . . . . . . . equivalent equation
