Answer:
the solution of given rational equation is x= 3/2
Step-by-step explanation:

We need to solve the above rational equation and find value of x
Finding LCM of 4 and (2x-1) we get 4(2x-1).
Multiplying 4(2x-1) on both sides of equation and solving

So, the solution of given rational equation is x= 3/2

Answer:
the first one first the second second and the last last
Step-by-step explanation:
2 1/5 + 22/5 = 4 2/5
9 2/5 + (-5 3/5)= 4 1/5
-8 2/5+9 1/5=1/15

m/8 < 4
m < 32
Answer:
48.5
Step-by-step explanation:
The constant of proportionality in this case is the speed at which Andrew travels.
We know that the speed is equal to:
v = d / t
We know the distance that is 145.5 miles and the time is 3 hours, replacing:
v = 145.5 / 3
v = 48.5 mi / h
which means that the equation would be:
y = k * x
where k, that is, the constant of proportionality is the velocity 48.5.
y = 48.5 * x
To check if for example x is worth 3, it would be:
y = 48.5 * 3
y = 145.5
