Answer:
x = -11
Step-by-step explanation:
2x + 23 + 9 = x + 21
Combine common factors
2x + 32 = x + 21
Subtract x from both sides
x + 32 = 21
Subtract 32 from both sides
x = -11

Answer:
A = 2 1/2 ft^2
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
A = 3 * 5/6
A = 5/2 ft^2
A = 2 1/2 ft^2
Answer: 06.45
Explanation: For this problem, it is essential to know that there are 24 hours in a day. With that said, we take our starting time of 16.45 and since we want to know what time it is 14 ahead (addition), we add the two numbers together.
16.45 + 14 = 30.45
Since there are only 24 hours in a day, and we have exceeded that value, we subtract 24.
30.45 - 24 = 06.45
And that is the time in Brisbane.
Alternatively, you can count time in 12-hour format and convert 16.45 to 4.45 pm by subtracting 12.
Knowing your start time is 4.45pm simply add 14 to that (or change the pm to an and add 2 since 14-12=2).
You will again get 6.45am.
Cheers.
