7x + 2y = 7<br> -14x + 2y = -11<br> Solve by substitution
kvasek [131]

Answer:

x = 6/7, y = 1/2

Step-by-step explanation:

7x + 2y = 7

-14x + 2y = -11

1) 7x + 2y = 7

2y = 7 - 7x

2) -14x + 2y = -11

-14x + 7 - 7x = -11

- 21x = -11-7

- 21x = - 18

x = 18/21 = 6/7

3) 2y = 7 - 7x = 7 - 7*(6/7) = 7 - 6 = 1

2y = 1

y = 1/2

Resuelve los problemas de una bodega que exporta tomates al extranjero
Dovator [93]

Answer:

1. 34.42 Toneladas

2. 28.640 toneladas

3. 38 toneladas

4.\frac{15}{10} o 1\frac{5}{10}

5.\frac{16}{6} o 2\frac{4}{6}

6.\frac{8}{4} o 2

1.1 Solucioné el problema convirtiendo el .25 en fracción.

2.1 Conviertes el denominador en el mismo buscando el minimo comun multiplo

3.1 0.099

\frac{1}{4}

\frac{1}{3}

\frac{2}{3}

0.7

0.75

1.1

\frac{3}{2}

Step-by-step explanation:

Acuerdate que para solucionar las fracciones mixtas solo tienes que dividir el denominador al nominador, por ejemplo en si tienes \frac{10}{3} entonces el 3 cabe 3 veces en el 10, y sobra 1, entonces quedamos que en mixta la fracción sería 3\frac{1}{3}

Entonces una vez que recordamos eso, podemos resolver los problemas de fracciones sin ningún problema vamos a resolver la número 4:

\frac{8}{10} +\frac{7}{10}

Como el denominador es igual, sólo sumamos el nominador:

\frac{8+7}{10}

\frac{15}{10}

Cómo el 10 cabe 1 vez en el 15, tenemos un entero y sobran 5:

1\frac{5}{10}
