If you could travel 450 miles in 5.5 hours, then how far could you travel in 7 hours?

I will use x as the distance traveled in 7 hours

450/5.5 = x/7.7 - set up proportion

5.5x = 3465 - cross products

5.5x/5.5 = 3465/5.5 - divide each side by 5.5

x = 630 - answer

hope this helps.

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
