Answer:
D. 5x + 3 = 17
Weight of each book = x pounds = 2.8 pounds
Step-by-step explanation:
Jada’s teacher fills a travel bag with 5 copies of a textbook. The weight of the bag and books is 17 pounds. The empty travel bag weighs 3 pounds. How much does each book weigh?
A. 3(x + 5) = 17
B. 3x + 5 = 17
C. 5(x + 3) = 17
D. 5x + 3 = 17
Weight of the empty travel bag = 3 pounds
Copies of book = 5
Weight of each book = x pounds
Total weight of 5 books = 5 * x
= 5x pounds
Total weight of the bag and books = 17 pounds
The equation is:
Total weight of the bag and books = Weight of the empty travel bag + Total weight of 5 books
17 = 3 + 5x
Can also be written as
5x + 3 = 17
Solve for x
5x + 3 = 17
5x = 17 - 3
5x = 14
x = 14/5
x = 2.8 pounds
Weight of each book = x pounds = 2.8 pounds
