Answer:
7 is the Anwser
Step-by-step explanation:
When you say 1 over 3, you are basically saying 1 divided by 3, or expressed as a rational number:

. in our rational number the denominator is 1, and the numerator is 3
Now, a rational expression is an algebraic expression in a rational for. If we apply the same to your problem. 4 over x-3 means 4 divided by x-3, or in mathematical notation:

. In this case, the numerator is 4, and the denominator is

.
We can conclude that the equivalent rational expression of <span>4 over x - 3 is </span>

.
Answer:
C
Step-by-step explanation:
When doing 4 divided by 2 you get 2. Looking at the sign it is saying 3 is greater than the number we solve for. Since we solved and got 2 we can double check and ask is 3 greater than 2? Yes it is so that would make the statement correct.
Hope this Helps :)
Answer: = 240 mph.
Step-by-step explanation:
Let x = speed of the plane.
t= time taken
As per given, we have
[Time = distance / speed]
From (i) and (ii), we get

Hence, the speed of the plane = 240 mph.
