If cheese is $4.40 per kilogramme, what should i pay for 200 grammes?

Cost of 200 gram chess  = $0.88.

Step-by-step explanation:

Given  : If cheese is $4.40 per kilogram.

To find : What should I pay for 200 gram.

Solution : We have given

1 kilogram = 1000 gram.

Cost of 1000 gram chess =  $4.40.

Cost of 1 gram chess = .

Cost of 200 gram chess =  .

                                        = $0.88.

Therefore, Cost of 200 gram chess  = $0.88.

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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