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.
Answer is b because it eliminates x when these two equations are combined
Ok, 7, 6, 5, and 4 are the integers.
Work - So, if you add 7 and 6 you get 13, and the problem tells you to multiply that by 2. After you multiply by 2, you should get 26, after getting that you move 2 numbers before 7 and 6, you should get to 4, the problem also tells us to make sure you multiply it by 3 but make it 14 less than you answer. Therefore, after doing the work you should receive the number 12, if you get your previous number, in our case, 26, you need to then, subtract 12 away from 26, and you should get 14 (the number you should be left with).
This is correct, Have a good day Mr. Abc
Answer:
-54
Explanation:
First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.
Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.
Now we can substitute -9 for x, so do 6×-9 and you get -54.
Hope this helps :)
