Answer:
a. 3x+6=30
b. 3(6+x)=30
Explanation:
a. As you know, x is the unknown variable. In the first question we know that there are 3 bags that weigh the same amount, however we don't know the amount of pounds that it weighs. So we can mark it with a variable (x). Since there is 3 bags we can multiply 3 by x to get the total weight. There is a 6 pound rice bag inside, and the total weight is 30. Hence, the equation 3x+6=30.
b. In this case, we ae told that each basket contains 3 boxes. with a 6 pound rice bag, and a bag of stuffing. We will represent the weight of the bag of stuffing with an x. The weight of a single box is x+6. Since there is 3 boxes, we can multiply the entire thing by 3.
