0.65x + 5 = 0.45x+ 10

25

Step-by-step explanation:

Move the variable to one side by subtracting 0.45x from 0.65x and you get 0.20 the divide 5 by 0.20

x = 25

Step-by-step explanation:

0.65x + 5 = 0.45x+ 10

Subtract .45x from each side

0.65x-.45x + 5 = 0.45x-.45x+ 10

.2x +5 = 10

Subtract 5 from each side

.2x+5-5=10-5

.2x= 5

Divide each side by .2

.2x/.2 = 5/.2

x =25

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.
