what plus 290 equals 400?

Answer 1

300 + 100

Answer 2

To solve the equation "x + 290 = 400," you would first subtract 290 from both sides to isolate the variable. This gives you x = 400 - 290, which simplifies to x = 110. Therefore, the value of x that satisfies the equation is 110.

Answer 3

Well, isn't that a happy little math problem we have here? If we have a number that we add 290 to and get 400, we can see that the missing number is 110. Just like painting a beautiful landscape, sometimes all we need is a little bit of patience and observation to find the answer.
