The right answer is letters
Arithmetic is a branch of mathematics that studies the numbers and the properties with them. The main properties are addition, subtraction, multiplication and division. Variables are non-constant values, so we use letters to assign a number to a variable and the operator that allows us to do this is =. For instance, if we have the variable x, we can say that this variable is equal to 4. Then:

Suppose the value of the variable changes to 5, then the new value of it is given by:

The rate of increase and decrease associated with Kalani's stock investments would be a 25% per year increase.
Therefore, the correct option of all the answer choices you listed is: C.
Answer:it doesnt matter what you choose for this one a or b
Step-by-step explanation:
∫4dy + 3dx
You can do this using Green's theorem. The line integral over the boundary of the closed triangle.
See the partial derivative of the partial derivative of 3 with respect to y = 0
You can see that now the line integral can be divided into three sides of triangle
hope this helps
Answer:
B. 
Step-by-step explanation:
Let n be the number.
We are asked to write an mathematical expression for the given word phrase.
One third of a number, n, would be
.
Two more than one third of a number, n, would be
.
We are told that Two more than one-third of a number is 8. We can represent this information in an equation as:

Therefore, option B is the correct choice.
