Hi there!
So we know that the two train together is a total of 192 tons and the difference of their weights is 120 tons...
Ok let think...
When we’re looking at the once place, you’ll see a two... this means that the two train both have a ending of 1 since 2 is split into 1...
That would be another clue..
Now let think again...
If it would be 151 and we subtract by 120.. we would get...
Well it ends with a 1 so it would be perfect but we have to see if 151 and 31 together adds up with the total of 192..
This means that train A could be 151 tons or 31 tons and train B can also be wither 151 tons or 31 tons...
Answer: They cannot meet because two skew lines do not intersect each other.
Explanation:
Skew lines is a concept used in geometry to define lines that do not intersect each other but are not parallel.
In this case, the lines are not parallel because they lie in different planes, which in turn, do not intersect each other.
Therefore, runing the lnes in different planes and in different directions, they cannot not, in spite of not being parallel, intersect each other, which is called that the lines are skewed.
Donna's and Charlie's paths are an exelent illustration of what skew lines are: since Donna's and Charlie are in different levels, as long as each remains in parallel levels, their paths wiil not meet each other.
The answer is “x”. “x” represents the missing number in the problem.
Example:
16+x=20
The missing number, 4, would be represented as x. Hope this helps!
Answer:
x is in the range [-1,4]
Step-by-step explanation:
I haven't worked with absolute value inequalities in awhile, but let's take a wack at this.
We are given the following inequality:
| 2x - 3 | <= 5
This implies two possible cases:
[1] -5 <= 2x -3
Or
[2] 2x - 3 <= 5
So let's solve x for both of these cases:
[1] -5 <= 2x - 3
-2 <= 2x
-1 <= x
[2] 2x - 3 <= 5
2x <= 8
x <= 4
So from these cases, we can say the following is true:
x >= -1 and x <= 4
Thus, we can write this in the form
-1 <= x <= 4
Or in interval notation:
{ x is element of reals | -1 <= x <= 4}
Also written as
x is in the range [-1,4]
Where the closed brackets represent 1 and 4 as possible answers whereas parenthesis would imply they were not.
Cheers.
