Answer:
The faster train goes 60mph
Step-by-step explanation:
s= speed
s+20 is the faster train.
Then you are given:
200/s+s+20=2
200=2*(2s+20)
4s+40=200
4s=160
s=40 is the slower train
40+20= speed of faster one
s=60 ;)
Another ratio of 13:27 is to write it as a fraction. This is to mean;
To solve a function like this, simply put the numerical value in place of the unknown variable for which you have to find the solution, for instance '-3' in this case.
g(x) = 2x-2
so to find g(-3), we just need to replace the x in the given expression by '-3'. Working is shown below:
g(x) = 2x-2
putting '-3' in place of x
g(-3) = 2(-3) - 2
g(-3) = -6 -2
g(-3) = -8
Answer:
If you are asking for the type of quadrilateral, then it could be a rectangle or a square.
Answer:
We are given the lengths of the two segments of the line. Using the addition postulate we can obtain the segment of the entire line.
Did you draw out the diagram. We know that the three points are collinear.
