Use a number line to add 3 + (-5).

Answer: -2

Step-by-step explanation: When your adding and subtracting positives and negatives, it helps to use a number line to visualise what's going on in the problem.

On a number line zero is in the middle. All numbers to the right of zero are positive and all numbers to the left of zero are negative.

So when your simplifying a problem like 3 + (-5), we start at zero and positive 3 takes us to the right. From there, -5 moves us 5 units back to the left and we end up -2. So 3 + (-5) simplifies to -2.

16 feet 10 minutes. 40 feet write as proportion
WINSTONCH [101]
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
