There are approximately 50, 000, 000 students enrolled in kindergarten through grade 12 in the United States. If this amount is written in scientific notation as 5 x 10^x, what is the value of x?
To write 50,000,000 in scientific notation, we need to move the decimal point 7 places to the left.
This gives us 5 x 10^7.
Therefore, the value of x is 7.
