Answer:
2/5 divided 1/2 as a unit rate .what do you mean
The <u>correct answer</u> is C) yes, the answer is written in scientific notation.
Explanation:
In scientific notation, we have a decimal number multiplied by a power of 10. The decimal number has the decimal point behind the first non-zero digit, and the exponent on the power of 10 tells us how many places to move the decimal.
In this problem, we have 5.6, which has the decimal after the first non-zero digit. We also have 10¹², which tells us to move the decimal 12 places.
This is in scientific notation.
2.22, when multiplied by 0.5, results in 1.11.
1.11, in turn, can be written as 111/100, which is a rational number.
D is the correct answer choice.
If you are looking to write an inequality equation that models this situation, then the answer would be: 
. The "at most" signals to use the less than or equal to sign.
4x + 6 < -6
subtract 6 from both sides
4x < -12
divide 4 on both sides
x < -3
