Answer 3

It seems like you have provided a set of mathematical equations with missing values. Let's solve them step by step:

1. 120 + ? = 460 To solve for the missing value, subtract 120 from both sides of the equation: ? = 460 - 120 ? = 340

2. ? + 89 = 689 Subtract 89 from both sides of the equation to find the missing value: ? = 689 - 89 ? = 600

3. 540 + 800 Simply add the two numbers together: 540 + 800 = 1340

So, the solutions are:

1. 120 + ? = 460 -> ? = 340
2. ? + 89 = 689 -> ? = 600
3. 540 + 800 = 1340
