Answer:
The answer is 10/143
Step-by-step explanation:
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
You can get 20 quarters for a five dollar bill. Just divide 5.00 by 0.25 and you get 20. To check, you can multiply 20 by 0.25 and you will get 5.00 or 5.
Answer:10.2 inches
Step-by-step explanation:
we know that
In this problem we have two cases
First case
The given lengths are two legs of the right triangle
so
Applying the Pythagoras Theorem
Find the length of the hypotenuse
substitute
Second case
The given lengths are one leg and the hypotenuse
so
Applying the Pythagoras Theorem
Find the length of the other leg
substitute
Find the difference between the two possible lengths of the third side of the triangle
so
