So in this problem, we have a piece of steel tubing here that is 19 and 3 eighth inches long.
00:11
And we're going to cut this at some point out here.
00:16
We can make a cut.
00:18
And the piece here that we're going to use will be 11 and 9 .16 inches.
00:27
And remember, whenever we cut something with a saw blade like this, that this cut is 1 .16 inch.
00:37
And so the question then is how long is this piece that's remaining? well, to find out how long the piece is remaining, we just add all these pieces up, right? we have 11 and 916th plus 1 .16 plus i'll call this x, this distance x, and all of that has to equal 19 and 3 eighths.
01:11
Okay, well, left and side, let's add these two terms together.
01:17
So this is 11 and 10 .16 plus x equal to 19 and 3 .8s...
