Answer:

x=11, y=10

Step-by-step explanation:

x= 6+ (1/2)y

x+y=21

substitute the first equation into the second equation:

(6+ (1/2y)) + y =21

to get:

y=10

then to find x:

x+ 10 = 21

x=11

unos amigos compraron 1/2 de pizza hawaiana 2/4 de peperoni 1/2 de pollo y 3/4 de salchicha ¿cuanta pizza compraron en total?​
sveticcg [70]

Answer:

Los amigos compraron 2 pizzas más \frac{1}{4}

Step-by-step explanation:

Para conocer la cantidad de pizza que los amigos compraron en total, debes sumar la cantidad de cada clase que compraron:

\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}

Para sumar estos valores, debes encontrar un denominador común. Como 4 es múltiplo de 2, el 4 puede ser usado como denominador común. Este común denominador se divide entre el denominador de cada fracción. El resultado de la división se multiplica por el numerador de la misma fracción. Una vez que se divide y se multiplica, el resultado se coloca en el numerador. Realizando el mismo procedimiento con cada fracción y se realiza la suma con los numeradores que resultaron:

\frac{1}{2} +\frac{2}{4} +\frac{1}{2} +\frac{3}{4}=\frac{2+2+2+3}{4} =\frac{9}{4}

Siendo \frac{9}{4} =2.25=2\frac{1}{4}, entonces <u><em>los amigos compraron 2 pizzas más </em></u>\frac{1}{4}<u><em></em></u>
