Step-by-step explanation:

Solve by Subsitution

x = 50 - y

Replace this into the second equation

y(50 - y) = 300

50y -  {y}^{2}  = 300

Write in standard form

-  {y}^{2}  + 50y = 300

Use the quadratic formula, and our answer will be

(6.97,43.02)

(43.02,6.97)

Please keep in mind that the answers may not be correct. I have tried my best to answer.

1. 83.333...% would fit. We must first solve for x. As you can see, we have a similarity in the picture. 16 and 4. It's 4. So, we multiply that by 6 which equal 24=x. Now, we know that space (Not provided) is 4. So, we just divide 20 by 4. It will equal 5, add the space not provided and becomes 6. All you gotta do is now divide 100/6. 16.666... Multiply by 5 since that is how much it is providing. Then, your answer will be 83.333...%

2. 88.888...% would fit. Like the above, we must solve for x. As you can tell, the situation is similar to the original. Divide 18 by 4, 4.5. Multiply 6 by 4.5, 27. Subtract 27 by 24, 3. Now we know that the space (not provided) is 3. Divide 24" by 3, 8. Add 1 due to the non provided space. 9. Divide 9 by 100, 11.111... Multiply by 8 and get the answer. 88.888...%

Katarina [22]

Answer:

$6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.

Step-by-step explanation:

Dado que una cooperativa de agricultores obtuvo en el año 2020 una utilidad de $42,600, de cuya suma destino el 15% para fondos de reserva, 18% para fondos de provisión y el 20% para fondos de operaciones, para calcular cada una de la suma​s se debe realizar el siguiente cálculo:

100 = 42,600

15 = X

42600 x 15 / 100 = 6390

100 = 42,600

18 = X

42600 x 18 / 100 = 7668

100 = 42,600

20 = X

42600 x 20 / 100 = 8520

Por lo tanto, $6390 se destinaron a los fondos de reserva, $7668 se destinaron a los fondos de provisión y $8520 se destinaron a los fondos de operaciones.
