Answer:
shouldn't it be all the same answer since it looks like a equilateral triangle
2x=3x+1
First, subtract 3x from both sides to get the variable on only one side
-x=1
Now, divide -x by -1 so that it can get rid of the negative sign and so the only thing remaining on the x's side is x.
Your final answer should be: x=-1
Answer:
Rational
Step-by-step explanation:
A number is rational if it can be expressed as a fraction. Because -0.1254 can be expressed as the fraction –627/500, it is rational.
Answer:
v=a+ 2e1= [3 1 1 1]
.
Step-by-step explanation:
Let a = 
and we know that
=±║α║₂= 2.
As we have gone over in class, the formula for v is v= a-
e1
with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1]

Answer:

Step-by-step explanation:
To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.
If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.
So

We also know that:
Since the express train travels 3 times faster than the freight train.
So, like both equations, we have to:

Then
miles in the opposite direction.
This is the distance you traveled in 15 minutes.
Therefore, the speed of the express train (
) is the distance traveled between the time it did
