A train traveled 12 miles in 30 minutes. At this rate, how far will it travel in 45 minutes? 35.5 miles

18 miles

27 miles

16 miles

The answer is 18 miles.

Step-by-step explanation:

The answer is 18 because 12 divided by 30 is 0.4 and 0.4 multiplied by 45 is 18.

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.

the answer is simply just 6n add the two together as they have an n
