The first thing we must do for this case is to take into account the following variable:
x = speed in miles per hour
Then, by definition we have to:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values:
250 = x * 5
Answer:
An equation that can be used to find the speed of the train is:
250 = x * 5
Answer: a-b+c+d =4
Step-by-step explanation:
The given system of equation is
from this we have the following matrices
the given matrix A =
On comparing Matrix with Matrix A
we have the following values
a=2 ,b=4,c=8,d=-2
Thus a-b+c+d =2-4+8+(-2)=4
Answer:
Turn 9 2/3 into an improper fraction, which is now 29/3x 3/1. And if you multiply this, you would get 29/1 since 87/3 is just 29, your answer would be 29 and the estimated producted would be 25.
