Find unit rate for 14 for 2.99

Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14.

Then we'll divide both the numerator and denominator by 14.

÷

Then we simplify and get:

14÷14=1     2.99÷14=.2135   We can round that to .21

The unit rate for each pound would be 1:.21

I don't know if that helped, but yeah. :)

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.
