Just to give you a visual for the first one, that you have x, i got to see it again, x minus 5 is less than 3, something like this, is that you can set this up as two different inequalities, that x minus 5 could actually be greater than negative 3 because the thought process is including the negative has to flip that inequality, or x minus 5 is less than 3.
00:30
So at this point, you could add 5 to the right.
00:35
So x would be greater than 2.
00:37
And at the same time, when i add 5 to the right on this one, x would be less than 8.
00:45
So by looking at that number line, which they kind of provide for you, 2 is important.
00:52
1, 2, 3, 5 is important, and 8 is important.
00:58
So the question that's asking you is that how many units you are equidistant on either side, because they're going from, well, i guess it's an open circle, from two to eight, that the first answer are less than three units away from five.
01:22
So technically the first blank is three.
01:27
And then, oops, i forgot to write from, the second blank is five.
01:33
And so how you can write your inequality, if you look at the way i have it, i guess i already did part two there, that we just have open circles going from two to eight.
01:46
And then the third one, we would write that inequality.
01:49
Two is less than x is less than eight.
01:53
So sorry, i kind of went out of order there...
