Answer:
A.Both of the students did the problem correctly.
Step-by-step explanation:
B. Nikki multiplied the fraction(8/3) to the items in the parentheses. Then multiplied each side with 3. Jon did the opposite. He first removed the fraction by multiplying each side by 3. Then he multiplied 2 to the items in the paranthesis.
C. I prefer Jon's method. Fractions can be tricky. I prefer to remove them as soon as possible. This time the items in the paranthesis had whole numbers. But had any of them been a fraction too, the problem would have gotten a lot more tricky and it would very easy to make a mistake or miscalculate something.
The answer is 50. You add all of the numbers in the data set, and divide it by the number of numbers in the data set. the sum of all of the numbers is 350, divide that by 7( the amount of numbers in the data set) and you get 50
Answer:
39,144,000 km
Step-by-step explanation:
Hi there!
Distance traveled = time * speed
Given speed: 233000 km/h
Given time: 7 days
It's important to note that our speed is given in per hours and out time is given in days. So in order to find how far the comet has traveled we must convert days to hours.
There are 24 hours in 1 day.
So to convert days to hours simply multiply amount of days by 24
24 * 7 = 168
So the comet has traveled for 168 hours
Now we can find distance traveled
Once again distance traveled = time * speed
Given speed is 233000 km/h
Given time is 168 hours
Distance = 168 * 233000 = 39,144,000
So the comet has traveled for a total distance of 39,144,000 km
