A number which is to be added to4-/5 to get -3 is

The answer is -11/5

Step-by-step explanation:

Let the number be A

-4/5 + A = -3

Multiply -5 through

-4/5 × 5 + A (5) = -3 × 5

-4 + 5A = -15

5A = -15 + 4

5A = -11

A = -11/5

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.
