How do you express 5 multiplied by x?

You express 5 multiplied by x as 5x.

In algebra, when you multiply a number by a variable, you typically write them next to each other without any symbol in between. This is a shorthand notation that makes expressions cleaner and easier to read. So, instead of writing 5 * x, you simply write 5x. This is understood to mean "5 times x."

This notation is part of the conventions used in algebra to simplify expressions and equations. For example, if x represents a number, then 5x means you take that number and multiply it by 5. If x were 2, then 5x would be 5 * 2, which equals 10.

Using this notation helps when you start working with more complex expressions and equations. For instance, if you have an equation like 3x + 5x, you can combine the terms to get 8x. This is much simpler than writing out 3 * x + 5 * x and then combining them.

Remember, the variable x can represent any number, and the expression 5x will change depending on the value of x. This flexibility is one of the powerful aspects of algebra, allowing you to solve a wide range of problems by manipulating these expressions.
