Part A: first multiply 2 by x and -3, then combine the like terms, after that add 6 from both sides, then subtract 6x from both side, the answer is -5.
 4x + 2(x-3) = 4x + 2x - 11
          4x +2x -6 = 4x + 2x - 11
           6x -6 = 6x - 11
           6x = 6x -11 +6
         6x = 6x -5
          6x-6x= -5 
         0 = -5 
 part B) add the like terms

Answer:  There is no solution to the equation ad we have used distributive property to solve the equation.

Step-by-step explanation:  The given equation is

4x+2(x-3)=4x+2x-11.

PART A:

The solution of the above equation is as follows:

4x+2(x-3)=4x+2x-11\\\\\Rightarrow 4x+2x-6=6x-11\\\\\Rightarrow 6x-6=6x-11\\\\\Rightarrow -6=-11,

which cannot be TRUE.

So, the equation will not have any solution.

PART B: We have used DISTRIBUTIVE PROPERTY to solve the equation, which states that

for any real numbers a, b and c

(i) a(b + c) = ab + ac,

(ii) (a + b)c = ac + bc.

Thus, there is no solution to the equation ad we have used distributive property to solve the equation.

If the tank is then field to capacity how many half-gallon bottles how many cords will it make?
lukranit [14]

Answer:

Divide 12 by 4 first to figure out how many gallons are in each 1/4 of the tank. 

12/4=3

So if I added another 1/4 to the capacity:

It could hold 15 gallons. 

All you have to do to find how many half bottles can be filled is to times 15 by two since we are filling half gallon bottles.

15x2=30

30 bottles.
