Answer:
C - 3 Books.
Step-by-step explanation:
The student borrowed 2 books on Monday, and another 4 books on Tuesday, so 2 + 4 = 6. Since the student later returned 3 of said books, we can do 6 - 3 = 3. The student ends up with 3 books in total.
Answer:
1.) Step-by-step In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1] 2
2.) Architecture and Construction. Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.
P=3r + 2s you need to get all the numbers and variables on the other side of the equation so that s is alone.
P -3r = 2s Subtract the 3r from both sides.
P- 3r /2 =s now divide the whole amount P-3r by 2 and you've got your answer!
