Ajet travels 420 miles in 2 hours. at this rate how far could the jet fly in 14 hours ? what is the rate of speed of the jet

In 14 hours, the jet will have traveled 2540 miles.

1) first, make a equation to be able to solve; 420/2 = x/14

2) next, you have to figure out what times 2 equals 14. here, it is 7. after that, you multiply 7 by 2 (which is 14) and do the same to the top of the fraction (240 times 7)

3) after you multiply it you get 240/2 = 2540/14

hope this helps !!

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

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.
