Math Problem Statement

(400 - x) / 2

Solution

The expression you've provided is:

400x2\frac{400 - x}{2}

This is a simple algebraic expression where xx is the variable. The fraction means that the difference between 400 and xx is being divided by 2.

If you need to simplify it or solve for xx, more context would be needed, such as an equation or additional instructions.

Would you like to simplify this further, or are you looking for a solution to a specific problem involving this expression?

  1. How would you solve for xx if 400x2=100\frac{400 - x}{2} = 100?
  2. What happens if you multiply both sides of 400x2=50\frac{400 - x}{2} = 50 by 2?
  3. How can you graph the equation 400x2=y\frac{400 - x}{2} = y?
  4. What would happen if you had 400+x2\frac{400 + x}{2} instead?
  5. How would you handle this expression in calculus if you wanted to take its derivative?

Tip: To simplify expressions like these, it often helps to isolate the variable by multiplying both sides of the equation by the denominator when solving.
