Un hipermercado necesita, como mínimo, 6 cajas de manzanas, 8 de peras y 10 de naranjas. Para proveerse puede acudir a dos proveedores A y B que suministran fruta en contenedores. Cada contenedor de A se compone de 1 caja de manzanas, 2 de peras y 1 de naranjas, y cuesta 60 €, mientras que cada contenedor de B se compone de 1 caja de manzanas, 1 de peras y 5 de naranjas, y cuesta 75 €. Averigua cuántos contenedores debe pedir el hipermercado a cada proveedor para cubrir sus necesidades con el mínimo coste posible y a cuánto ascendería este coste.

50-38=12

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
