What is an expression that contains a variable a number and at least one operation?
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.
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
When K equals 10 what is the value of this expression 3k?
k = 10 3k = 30 When a number appears next to a variable (like "k") it usually means multiply the number times the variable.
How can 24 multiplied by 3 be written as a numerical expression?
To write the expression for "24 multiplied by 3," you would use the multiplication symbol "×" or "*", which represents the operation of multiplication. The numerical expression for this would be "24 × 3" or "24 * 3." This expression indicates that you need to multiply the number 24 by the number 3 to find the product.
What is the product of 8 and n?
Well, honey, the product of 8 and n is simply 8n. It's as easy as that! So, if you need to find out what 8 times any number n is, just multiply them together and you've got your answer. Math can be a piece of cake when you break it down like that!

What is an expression that is a number and a variable or a product of a number and one or more variables?
In Algebra a term is either a single number or variable, or numbers and variables multiplied together.
What does a number and two letters mean in algebra?
Oh, honey, that's just a variable! A number and two letters in algebra usually represent a mathematical expression or equation where the number is multiplied by the variable. It's like the algebraic version of "X marks the spot."
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
Why replacing variable for a number in an expression or equation is called substituting?
Because you are substituting a number for a variable. Like substituting salt for sugar in a cake recipe. Although you really shouldn't do the latter.
When K equals 10 what is the value of this expression 3k?
k = 10 3k = 30 When a number appears next to a variable (like "k") it usually means multiply the number times the variable.
How do you write four more than half a number as a variable expression?
n/2 + 4
Is 3x a term?
Oh, dude, like, totally! So, a term in math is like a single mathematical expression, right? And 3x is totally just one term because it's like, one number (3) multiplied by a variable (x). So, yeah, 3x totally qualifies as a term in math lingo.
What is an expression for the product of a number and 20?
For any two or more multiples in algebra. they are written as '2x' or 'ab' or '3ab' NB In algebra the multiplication sign 'x' is NEVER' shown. The '2x' means '2' multiplied to 'x' , or similarly 'ab' means 'a' multiplied to 'b'.
Is x squared considered a variable?
Oh, dude, x squared is not technically a variable itself, it's more like a term in an algebraic expression. The variable is actually just "x," but when you square it, you get x squared. It's like the cooler, more powerful version of x. So yeah, x squared is not a variable, it's just x being all squared up and stuff.
Do a variable expression consist only of numbers?
No, because numbers never vary. A variable expression must have something in it that can take on different values, usually a letter, like 'x' for example.
