Average speed is calculated by dividing the total distance travelled by the time interval. For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).
The answer for 10x - 2y = 20 is y= 5x - 10
The answer for 5x = y + 10 is y = 5x - 10
so basically from this 5x - 10 is the results and 10x - 2y = 20 and 5x = y + 10 are different problems that lead to the same result, hope this helps
Answer:
4%
Step-by-step explanation:
After losing 4.17, it came down to 100.08, so the opening price was:
100.08 + 4.17 = 104.25
To find percentage decline, we find the ratio of the "change" (which is 4.17) divided by the opening (original) price, which is 104.25. Then we multiply that fraction by 100 to get our percentage decline.
So,

Thus, the
percentage decline = 4%
