Answer:

x=1-5√3, x=1+5√3

Step-by-step explanation:

-3x^2 + 224 = — 6х + 2

add 6 on both sides

-3x^2+224+6x=2

subtract 2 on both sides

-3x^2+222+6x=0

rearrange for the quadratic formula

-3x^2+6x+222=0

use the quadratic formula

x=1-5√3, x=1+5√3

The cost of 90 kg of rice is 4500. what is the cost of 2 quintal of rice?​
gayaneshka [121]

Answer:

The cost of 2 quintal of rice is $10,000.

Step-by-step explanation:

To determine the cost of 2 quintals of rice, knowing that 90 kilos of said product is worth $ 4,500, it is first necessary to establish the equivalence between quintals and kilograms. In this regard, a quintal is equivalent to 100 kilograms, so 2 quintals are equivalent to 200 kilos.

Now, to determine the cost per kilogram of rice, the following calculation is required:

4,500 / 90 = X

50 = X

Therefore, 1 kilogram of rice costs $ 50. Thus, since 200 x 50 equals 10,000, 2 quintals of rice will cost $ 10,000.
