Question

2160:45-(799-665)•67

Answer 1

2160:45-(799-665)•67=48-134•67=48-8978= -8930

Answer 2

Let's solve the expression step by step:

1. First, perform the subtraction inside the parentheses: 799 - 665 = 134

2. Next, multiply the result by 67: 134 * 67 = 8978

3. Finally, subtract the calculated value from 2160 hours and 45 minutes (2160 hours can be represented as 2160 * 60 minutes): 2160 hours = 2160 * 60 = 129600 minutes

129600 minutes + 45 minutes = 129645 minutes

129645 minutes - 8978 = 120667 minutes

Now, let's convert the minutes back to hours and minutes: 120667 minutes ÷ 60 = 2011 hours and 7 minutes

So, the final result is 2011 hours and 7 minutes.
