Line above the repeating number
7n-4=31
7n=31-4
7n=27
n=27/7
:n=3
It’s equation and it’s really easy to solve
Answer:
Step-by-step explanation:
A
What are the numbers? I cant see the answers, but it would be one of the segment addition postulate ones
Answer:
I thinks its 3.91 x 10^3
Step-by-step explanation:
follow these steps
Step 1
To find a, take the number and move a decimal place to the right one position.
Step 2
Now, to find b, count how many places to the right of the decimal.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
