Select the postulate of equality or inequality that is illustrated.
DaniilM [7]

Answer: Transitive Postulate of Inequality (last option)

Explanation:

Let's say we have a vacation where we go from City A, to City B, then to City C. We can use the notation A \to B \to C. If all we cared about was the first and last cities, then we basically say A \to C taking a shortcut so to speak.

This analogy is useful to describe the transitive property.

The equality version is where if we had a = b and b = c, then a = c.

The inequality version is where if we had a < b and b < c, then a < c. In this case, c = 2.

In a sense, its like linking together metal chains. A leads to B which leads to C. So we can just jump from A to C.

It might help to draw out a number line and pick values for a and b like a = 0 and b = 1. That way you can see how a < b, b < c and a < c all tie together.

The expression on the left side of an equation is shown below.
77julia77 [94]

Answer:

(x=1) - Below

0-6 = 6

1

(-6x) = -6

(0 - (6x))+6 = 12

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

−6x+6−6=0−6

−6x=−6

Step 2: Divide both sides by -6.

−6x/−6 =− 6/−6

Step 3: x = 1
