<span>Anna learns in her science class that the human eye blinks an average of 4,200,000 times a year. What is this number expressed in scientific notation?</span>
Answer:
Option B
Step-by-step explanation:
I did the test and I got it right.
Subtract the two over to cancel it out
3x=36
then divide by 3 to get an answer of
x=12
The common denominator would be 6. Since, the least common multiple of 3 and 6 is 6.
3:
3, 6, 9
6:
6, 12, 18
Least common multiple is 6
