Answer:
I think this is the right answer but last two signs are incorrect
Hope this will help
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
What is 40/100 as a decimal?
To write 40/100 as a decimal you have to divide numerator by the denominator of the fraction.

Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)
