Answer:
9.9 gallons
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.


Now, lets put the values above back into the equation:

Lets solve this equation. First we divide 2,475 by 250, making x by itself.


This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.

Answer:
(D) 
Step-by-step explanation:
Two variables x and y are proportionally related if they can be written in the form y=kx, where k is the constant of proportionality.
From the given options, if 
(B)
is of the form y=kx
(C)
is of the form y=kx with
as
in its lowest form.
(C)
is of the form y=kx with
as
in fractional form.
On the Contrary,
In Option D,
does not represent a proportional relationship between x and y. The constant of proportion is supposed to be a product of x.

The slope is 2
y=2x + b
Plug in a point to solve for b
8 = 2(3) + b
8 = 6 + b
b = 2
The equation is y = 2x + 2
I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.
