-4

Step-by-step explanation:

12x + 4 = 7x -16, Lets start off with subtracting the 4 from the left side

12x = 7x -20. The reason for this is because what you do to one side you must do to the other making -20 on the right side

Now we have to subtract 7x from the right side so we can divide later on making it 5x = -20

Final step is to divide 5x/5 = -20/5 making the answer

x= -4

An easy way to check is to multiply -4 in each spot that has the variable x, so 12(-4) + 4 = 7(-4) -16  the end out would be -44 = -44 meaning all the work is correct

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.
