Is there a solution to the problem 1/4 (12-4x) = 3-x

×= 3/4

Step-by-step explanation:

1/4(12-4×)=3×

1/4 × 12-4×/1 =3×

3×= 3- ×

3=3× + ×

3= 4×

× =3/4

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 1/4*(12-4*x)-(3-x)=0

Simplify   1/4

(1/4 • (12 - 4x)) -  (3 - x)  = 0  

3.1     Pull out like factors : 12 - 4x  =   -4 • (x - 3)  

 (3 - x) -  (3 - x)  = 0

 4.1      Pull out     3-x

After pulling out, we are left with :

     (3-x) • ( 1 +( (-1) ))

0  = 0

Step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
