Answer 3

Let's solve the expressions step by step:

1. $60 + (1000 - 580)$ $60 + (1000 - 580) = 60 + 420 = 480$

2. $700 - (50 \div 5) \times 4$ First, solve the division and then the multiplication: $50 \div 5 = 10$ Now, substitute into the original expression: $700 - 10 \times 4 = 700 - 40 = 660$

3. $500 \div (400 - 50)$ First, solve the subtraction inside the parentheses: $400 - 50 = 350$ Now, substitute into the original expression: $500 \div 350 = 1.4286 \approx 1.43 \text{ (rounded to 2 decimal places)}$

So, the values for the given expressions are:

1. $60 + (1000 - 580) = 480$
2. $700 - (50 \div 5) \times 4 = 660$
3. $500 \div (400 - 50) \approx 1.43$ (rounded to 2 decimal places)
