Three and eight times a number.
You can use the common X multiplication symbol, a dot, or use parenthesis with a coefficient next to them.
To write a verbal expression for (3x - 4), you can say "three times a number (x) minus four." This conveys the mathematical operations involved: multiplying the variable (x) by three and then subtracting four from the result.
An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.

An equation with two equal signs is not a valid mathematical expression, as an equation should have only one equal sign to show the balance between the two sides. If you encounter an expression with two equal signs, it may be a mistake or a misunderstanding of the mathematical concept. To solve an equation correctly, ensure there is only one equal sign and follow the standard procedures for isolating the variable on one side of the equation.
The term "verbal expression" in mathematical terms refers to a math phrase or statement that uses words or letters instead of using numbers. An example of this might be "Three divided by two" instead of "3/2."
No, but six eights can be reduced to three fourths.
The expression "3t" represents three times the variable "t." In mathematical terms, it is simply a multiplication of the number 3 by the value of t. If you know the value of t, you can substitute it into the expression to find the result. For example, if t = 2, then 3t = 3 × 2 = 6.
The expression (6 - 2x - y) represents a mathematical equation involving three variables: (6), (2x), and (y). It can be interpreted as a linear expression where (2x) and (y) are subtracted from 6. To evaluate it, you would need specific values for (x) and (y). Without those values, it remains an expression rather than a numerical answer.
Yes, "three times three" is an expression that represents the multiplication of the number three by itself. It can be mathematically written as (3 \times 3), which equals 9. This expression is often used to illustrate basic arithmetic operations.
"An expression of three terms" means that the expression has three parts, combined by plus or minus signs. Within each of these parts (terms), there can be a single number or variable, or a product or division involving several other pieces.
