On a road trip, yousef drove the same distance everyday for 8 days. on the ninth day, he drove 100 km. he drove a total of
1,700 km. how many kilometers did he drive on each of the first 8 days? and this is the choices x/8 +100=1700. 100x+8=1700. 8x+100=1700. 8x-100=1700

8x+100=1700

Step-by-step explanation:

8x+100=1700

8x+100-100=1700-100

8x=1600

8/8x=1600/8

x=200

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.

b
