Kate ships two copies of a small book in an envelope that weighs 4 ounces. the total weight of the shipment is 18 ounces. the equation 2w + 4=18 represents this situation. What is the weight of each book?

Respuesta :

w represents the weight of each book
2w + 4 = 18
2w = 18 - 4
2w = 14
w = 14/2
w = 7 oz <===
