Answer 3

To evaluate the expression 720 ÷ (440 - 350) × 4 + 490 ÷ 70 + 18 - 9, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction):

1. Start with the parentheses: (440 - 350) = 90.

Now the expression becomes: 720 ÷ 90 × 4 + 490 ÷ 70 + 18 - 9.

2. Perform the division: 720 ÷ 90 = 8.

Now the expression becomes: 8 × 4 + 490 ÷ 70 + 18 - 9.

3. Continue with the division: 490 ÷ 70 = 7.

Now the expression becomes: 8 × 4 + 7 + 18 - 9.

4. Perform the multiplication: 8 × 4 = 32.

Now the expression becomes: 32 + 7 + 18 - 9.

5. Perform the addition and subtraction from left to right:

32 + 7 = 39. 39 + 18 = 57. 57 - 9 = 48.

Therefore, the value of the expression 720 ÷ (440 - 350) × 4 + 490 ÷ 70 + 18 - 9 is 48.
