Question

Nathan lifted 13 boxes and Steven lifted 15. The boxes Nathan lifted each weighed 12 Ib more than the boxes Steven lifted. Which of the following is NOT an expression that represents the total weight of the boxes Nathan lifted?

(A) 12(13 + x)
(B) 13x + 12
(C) 12x
(D) 15x

Answer 1

To find the total weight of the boxes Nathan lifted, we multiply the weight of each box by the number of boxes Nathan lifted.option (D) 15x

Step-by-step explanation:

To find the expression that represents the total weight of the boxes Nathan lifted, we need to consider the given information. Let's assume the weight of the boxes Steven lifted is x. Since the boxes Nathan lifted each weighed 12 pounds more than the boxes Steven lifted, their weight would be x + 12.

Now, to find the total weight of the boxes Nathan lifted, we multiply the weight of each box (x + 12) by the number of boxes Nathan lifted (13). So the expression that represents the total weight of the boxes Nathan lifted is 13(x + 12), which is equivalent to option (A) 12(13 + x). Therefore, option (D) 15x is NOT an expression that represents the total weight of the boxes Nathan lifted.
