<h3>You have the correct answer. It is choice C) additive inverse.</h3>

The additive inverse is the idea of adding a negative number, which is the same as subtraction. Example: 2 + (-3) = 2-3

Based on the example above, if we start off with 3 and add on its additive inverse -3, then 3 + (-3) = 3-3 = 0. In general, x + (-x) = x-x = 0. So adding any number with its additive inverse gets you 0 every time.

-----------------------------------------------

Extra info:

  • Choice A is ruled out because the commutative property of multiplication is the idea that we can multiply two numbers in any order we want. Eg: 7*8 = 56 and 8*7 = 56, so 7*8 = 8*7
  • Choice B is ruled out as well. The commutative property of addition is similar to the rule mentioned in choice A. But now we're adding. This rule says we can add two numbers in any order. Eg: 4+5 = 5+4 = 9
  • Choice D is ruled out also. The multiplicative inverse of x is 1/x. Multiplying the two together gets you 1. Keep in mind that x cannot be zero. Example: The multiplicative inverse of 99 is 1/99, since 99*(1/99) = 99/99 = 1.

Give your answer with an exponent
Klio2033 [76]
5³*5^6=5^9
8^7/8²=8^5
9^7/9^11=1/9²
4^5^3=4^15

when multiplying like bases you add exponents. when dividing like bases you subtract exponents. when reasoning a number to a power then to another power you multiply exponents

The distance from Earth to the moon is 2.39 × 105 miles, and the distance from Earth to Mercury is 9.2 × 107 miles. Approximatel
malfutka [58]

Answer:

(D) 400

Step-by-step explanation:

It is given that The distance from Earth to the moon is 2.39 × 105 miles, and the distance from Earth to Mercury is 9.2 × 107 miles. Then,

Distance from Earth to Mercury compared to the distance from Earth to the moon is given by:

\frac{distance from Earth to Mercury}{distance from Earth to the moon}=\frac{9.2{\times}10^7}{2.39{\times}10^5}

=3.849{\times}10^2

=384.9

≈400.

therefore, option D is correct.
