1. Simplify the inequality 
2. Separate terms with x and without x in different sides:
3. Add similar terms:
4. Divide by 21.42:
Answer: correct choice is C.
The correct answer for the question that is being presented above is this one: "(1) <span>For all real numbers a and b, a + b = b+ a; </span>(2) For all real numbers a and b, ab = ba; (3) <span>For all real numbers a, b and c, (a + b) + c = a + (b + c); (4) </span><span>For all real numbers a, b and c, a (b + c) = ab + ac." </span>
The correct answer is: Commutative Property
Further Explanation:
The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.
<u>Commutative Property of Addition:</u>
The Commutative Property of addition means that an expression can be written as a + b = b + a.
<u>Commutative Property of Multiplication:</u>
The Commutative Property of multiplication means that an expression can be written as a • b = b • a
Hence, the correct answer is: Commutative Property
Keywords: Commutative property, addition, multiplication

The first thing we must know in this case is that the distance is equal to the speed for time.
We have then:
For Chris:
d1 = 40 * t
For Amy:
d2 = 60 * (t-2)
The distance between both will be given by the hypotenuse of the rectangle triangle:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
Answer:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
