What is an expression that contains one variable?
5+3x(7-2)
Write an expression using a variable?
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.
What is a combination of numbers variable and at least one operation?
A combination of numbers, a variable, and at least one operation can be represented mathematically as an expression. For example, in the expression ( 3x + 5 ), ( 3 ) and ( 5 ) are numbers, ( x ) is the variable, and the operation is addition. This expression illustrates how numbers and a variable can interact through mathematical operations.
Simplify the variable expression which is 6x plus 1 plus 7-3x.?
3x + 8
Can you add or subtract a number with a variable and a number without one?
Yes, you can add or subtract a number with a variable and a number without one, but they cannot be combined into a single term. For example, you can simplify the expression (3x + 5) to show that it consists of a variable term (3x) and a constant term (5), but they remain separate. The result is (3x + 5), not a single term.
24x square plus 17x-20?
It is a quadratic expression in the variable x.
What is value of an expression?
When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
What is an expression with one variable?
3x+2 x is a variable. A variable is a symbol (x, y, etc...) that does not have an assigned value.
What does cube in algebraic expression mean?
it means you multiply the number or variable by it self three times.For example,43 = 4*4*4 = 6453 = 5*5*5 = 125x3 = x*x*x3x3 = 3*x*x*x(3x)3 = 3x*3x*3x= 27x3
What is -3x-5-14?
It is an expression that is equivalent to -3x-19.
What expression is equivalent to 5 plus 3x plus 10?
The expression equivalent to 5 plus 3x plus 10 can be simplified by combining the constant terms. Adding 5 and 10 gives 15, so the expression simplifies to 3x + 15. Therefore, the equivalent expression is 3x + 15.
What is the variable in the expression 7s -5?
