7+(__)+5

1 answer

To find the missing number in the expression \(7 + (___) + 5\) that results in a specific total, you first need to decide on the total you want to achieve. If you are looking for the sum of all parts without specifying a total, here's how it can be approached:

  1. Combine the known numbers: \(7 + 5 = 12\).
  2. Let \(x\) be the missing number in the parentheses, then the equation can be expressed as: \[ 12 + x = \text{total} \]

If you have a specific total in mind, you can replace "total" with that number and solve for \(x\).

For example, if the total you want is 20: \[ 12 + x = 20 \] Then: \[ x = 20 - 12 = 8 \]

Thus, the missing number would be \(8\) if your goal total is \(20\). Please provide a specific total if you have one in mind!
