He just switched sides of the variables and numbers. Instead if adding the opposite.
Answer: Choice B) Integers include whole numbers and natural numbers.
======================================================
Explanation:
Let's go through the four answer choices to see which are true or false.
- A) False. A rational number like 2/3 is not a natural number (1,2,3,4,...). This is one counterexample out of infinitely many.
- B) True. The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically positive and negative values that don't have fractional or decimal components. Zero is included.
- C) False. Similar reasoning as choice A above.
- D) False. A natural number like 7 can be written as 7/1, which means it is a rational number. Any rational number is of the form a/b with a,b being integers and b is nonzero.
C because it says product which means multiply an the only one that does is c
Answer:
27.5 is the width
Step-by-step explanation:
First set up an equation.
(w+1)+w=56
This simplifies to...
2w+1=56
Now you need to isolate the w. Subtract 1 on both sides.
2w=55
Now divide 2 on both sides.
55/2 = 27.5
w=27.5
