In the expression (10 + 6h), the number 10 represents a constant value or a fixed amount. The variable (h) typically represents a quantity that can change, often associated with a specific context, such as hours or height. The coefficient 6 indicates that for each unit increase in (h), the total value of the expression increases by 6. Thus, the expression as a whole reflects a linear relationship where the total value depends on both the constant and the variable's contribution.
16x
X+6. Variable (x)
To write the quotient of a number and 6 as an expression, you can represent the number as a variable, such as ( x ). The expression would then be written as ( \frac{x}{6} ). This indicates that the number ( x ) is being divided by 6.
The number is called the coefficient of the variable
To write the quotient of 16 and a number, you can represent the unknown number with a variable, such as ( x ). The expression for the quotient would then be ( \frac{16}{x} ). This indicates that 16 is being divided by the variable ( x ).
the def for variable is a letter or symbol used to represent a missing number in an algebrac expression
16x
X+6. Variable (x)
it is the number you would use to solve the problem
x + 138
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
The number is called the coefficient of the variable
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
any number at all
The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.
It is the coefficient of the variable
