30+(60-30):7

To solve the expression \(30 + (60 - 30) \div 7\), follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets: Calculate the expression inside the parentheses. \[ (60 - 30) = 30 \]

2. Division: Next, divide. \[ 30 \div 7 \approx 4.2857 \]

3. Addition: Finally, add the result to 30. \[ 30 + 4.2857 \approx 34.2857 \]

Therefore, the result of the expression is approximately 34.29.
