Quantity is the measurement of something, so think of it like saying “how much of...”
New Orleans is an example of a city that experienced both a high decrease in population and a high increase in population in the span of three years. Explain the factors that led to these rapid population changes.
Answer:
An expression is one or more terms in an algebraic phrase. An expression does not contain the = sign because it is a phrase. Some examples of algebraic expressions are 2x, 5x + 3, 8m - 5m + 10
Evaluate an Algebraic Expression
To evaluate an algebraic expressiontext annotation indicator for x = 3, means to replace the variable x with the number 3 and then simplify by following order of operations.
Example:
Evaluate the following expression for x = 3.
3 xtext annotation indicator + 5
3(3) + 5text annotation indicator
= 9 + 5
= 14
Write an Algebraic Expression
To write an algebraic expression, look for key words that tell you what operation (add, subtract, multiply, or divide) to use.
Example:
Write an algebraic expression for: The product of x and 5 .
The key word here is product . You may recall that a product is the answer obtained when you multiply. That means we want to multiply x and 5, so we write the expression as 5 x . It should be written the standard way by putting the coefficient in front of the variable.
Step-by-step explanation:
Answer:
the correct answer is B
Step-by-step explanation:
got it right!!!!
Answer:
1.Step 1: Simplify each side, if needed.
2.Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
3.Step 3: Use Mult./Div. ...
4.Step 4: Check your answer.
I find this is the quickest and easiest way to approach linear equations.
5.Example 6: Solve for the variable.
