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
. If all we cared about was the first and last cities, then we basically say
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.
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
distribute 3 to the 2x and -1 by multiplying
6x - 3 = 6
add 3 to both sides to get 6x by itself and it keeps both sides equal
6x = 9
divide by 6
x = 9/6 = 3/2
x = 3/2
