Answer:
The simplification for the expression is given as =( 7 + 2(a-3))/(a-3)
Step-by-step explanation:
To simplify the expression we will first convert the words to values in numbers and alphabets.
StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction
= 5/(a-3) -4/2 + 2/(a-3)
Having done that, let's move on and simplify the expression.
5/(a-3) -4/2 + 2/(a-3)
= 5/(a-3) -2+ 2/(a-3)
= 5/(a-3) + 2/(a-3) -2
= 7/(a-3) -2
=( 7 + 2(a-3))/(a-3)
By definition we have to:
v = d / t
Where,
v: speed
d: distance
t: time
The time in hours is given by:
t = 4 + (45/60)
t = 4.75 hours
Substituting values we have:
v = 456 / 4.75
v = 96 km / h
Answer:
the speed of the train is:
v = 96 km / h
Hi there!
First, you do first 4x38.15=152.60 then you do 0.12.50x380.50=47.56 then you add total of the result that is how much she own the rental company.
