Answer:
X= Mary’s wages
2x-20=120
Add 20 to both sides
2x=140
Divide both sides by 2
X=70
$70
Step-by-step explanation:
The property of real numbers that was illustrated in the above example is known as the: D. inverse property.
<h3>What is the Inverse Property of Real Numbers?</h3>
The inverse property of real numbers states that if you add the opposite of a number together with that number, the result would be zero.
For example, if "a" represents a number, the opposite of the number "a" is -a.
Applying the inverse property of real numbers, it states that: a + (-a) = a - a = 0. Both numbers will cancel each other to give zero.
In the same vein, as shown in the image given above:
6 is a number
The opposite of 6 is -6.
Applying the inverse property of real numbers, we have:
6 + (-6) = 0.
In conclusion, we can state that given the expression, 6 + (-6) = 0, the property of real numbers that was illustrated in the above example is known as the: D. inverse property.

Frodo can run 1 miles in 1 hour
Subtract 4x from both sides
Then divide both sides by 9 to isolate y
Y=(6-4x)/9
