D varies directly with t means
d=kt
105=3k
divide both sids by 3
35=k
d=35t
when t=8
d=35(8)
d=280
B
There are 318 kilometers in 318000000 centimeters. <span />
3x=9 is C
4x+12 is A
X+1 is B
Solution :
It is given that :
lies in the first quadrant.
And 
lies in the fourth quadrant.
Since, 
and 
(given)
Similarly
(IVth quadrant)
Therefore,
I=PRT
I=intrest
p= starting balance/initial balance
r= rate
t=time
i=175,000x.05x1
i=8750
this is the intrest rate the amount given in one year
you need to add this to the first amount since its is simple interest not compound
