Respuesta: x/2,5=y/5=4/5=0,8
x/2,5=y/5
Multiplicando ambos lados de la ecuación por 5:
5(x/2,5)=5(y/5)→2x=y→y=2x
Sustituyendo y por 2x en la ecuación x+y=6:
x+2x=6
Resolviendo para x: Sumando términos semejantes:
3x=6
Dividiendo ambos lados de la ecuación entre 3:
3x/3=6/3
x=2
Sustituyendo x por 2 en la formula y=2x
y=2(2)→y=4
Determinando la proporción:
x/2,5. Sustituyendo x por 2:
2/2,5
Multiplicando numerador y denominador por 2:
2*2/(2,5*2)=4/5
La proporción es 4/5=0,8
Si lo hacemos con y:
y/5
Reemplazando y por 4:
4/5=0,8 (la misma proporción)

Answer:
The answer to this question is 12 inches.
Step-by-step explanation:
This is because 288 + b^2 = 432. After further calculations you can conclude that b = 12.
The diary farmer should use 1000 pounds of 85 % protien and 55 % of 200 pounds to make 1200 pounds of a high-grade 80% protein ration
<em><u>Solution:</u></em>
Let the amount of 85 % protien supplement be "x"
Then amount of 55 % protien be (1200 - x)
According to given question,
85 % of "x" protien supplement + 55 % of 1200 - x protien used to get 80 % of 1200 pounds
85 % of x + 55 % of (1200 - x) = 80 % of 1200

Pounds of 85 % protien used = 1000 pounds
Then pounds of 55 % protien used = 1200 - 1000 = 200 pounds
Thus he should use 1000 pounds of 85 % protien and 200 pounds of 55 % protien to get 1200 pounds of a high-grade 80% protein ration
