Answer:

  • 7 kg

Step-by-step explanation:

Let the added flour is x kg.

<u>We have following equation showing the total amount:</u>

  • 8x + 14*5 = (14 + x)*6
  • 8x + 70 = 6x + 84
  • 8x - 6x = 84 - 70
  • 2x = 14
  • x = 7

  • Cost of unbleached flour=14(5)=70

Now

Let required bleached flour be x kg

Then

\sf\longmapsto 8x+70=6x

\sf\longmapsto 8x-6x=70

\sf\longmapsto 2x=70

\sf\longmapsto x=35kg

Write an inequality for the graph
natima [27]
The open circle means the inequality will be greater than or equal to (≥) or less than or equal to (≤).
A closed circle means the inequality will be greater than (>) or less than (<)

An arrow pointing right to increasingly positive values means the inequality is getting greater (> or ≥)
A narrowing pointing left to increasingly negative values means the inequality is getting lesser (< or ≤)

So for this graph with an open circle and rightward pointing arrow, “x” will be some number on the number line greater than the first point of -38:
x > -38

Joaquín compró una docena y media de factura la docena son parte de grasa dos tercios tiene dulce de leche y el resto son medial
Juli2301 [7.4K]

Answer:

2 facturas de grasa.

12 facturas con dulce de leche

4 medialunas

Step-by-step explanation:

Una docena contiene 12 facturas y media docena contiene 6 facturas. Entonces Joaquin compro un total de 18 facturas (12+6). Si la novena parte (1/9) de las facturas son de grasa entonces solo multiplicamos esta fraccion por la totalidad de las facturas.

18 * (1/9) = 2 facturas de grasa.

La cantidad de facturas que tienen dulce de leche son dos tercios (2/3) de la totalidad. Entonces multiplicamos esta fracion for la totalidad.

18 * (2/3) = 12 facturas con dulce de leche

Por final, la cantidad de media lunas es el resto de las facturas, entonces descontamos las facturas de grasa y con dulce de leche de la totalidad para saber cuantas facturas son medialunas

18 - 2 - 12 = 4 medialunas
