To write a variable expression for "W increased by 4," you simply take the variable ( W ) and add 4 to it. The expression would be written as ( W + 4 ). This indicates that you are taking the value of ( W ) and increasing it by 4 units.

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.
You can write an expression with a variable in many different ways. First it all depends on what the word problem says. For Example : *Three times a number increased by four is less than eight. The answer would be 3x+4<8 or it could be written as 8>4+3x it will equal to the same amount. It doesn't matter what variable you use if it doesn't have an amount. Because all variables equal to 1, you can use any letter. REMEMBER EXPRESSION HAVE >,<, OR = . WHILE EQUATIONS HAVE ONLY = .

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
y increased by 4 is written as: y + 4
In the expression (4 + 5n), the coefficient is the number that is multiplied by the variable (n). Here, the coefficient of (n) is 5. The constant term in the expression is 4, but it does not have a variable associated with it. Thus, the coefficient of (n) is 5.
To express "7 times a number increased by 4" mathematically, you would write it as 7x + 4, where x represents the unknown number. This expression indicates that you multiply the number by 7 and then add 4 to the result. So, if the number is 5, the expression would be 7(5) + 4 = 35 + 4 = 39.
