Norman weighed his loaded truck of apples at a weigh station. It weighed 15 tons 100 lbs. His empty truck weighed 3 tons 200 lbs
Andreas93 [3]
11 tons, 1,900 lbs.  (or you could say 23,900 lbs, it's the same)

1 ton equals 2000 lbs.
15 tons 100 lbs = 30,100 lbs
3 tons 200 lbs = 6,200 lbs.
30,100 - 6,200 = 23,900

Entre Celia y Quique suman 14€. Si Celia tuviera 1 €, tendría el doble de dinero que Quique.¿ Cuanto dinero tiene cada uno?
denpristay [2]

Answer:

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

Step-by-step explanation:

Representemos la cantidad de dinero

Celia tiene = x

Quique tiene = y

Entre Celia y Quique suman 14 €.

x + y = 14

x = 14 - y

Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.

Por lo tanto,

x = 2 años

Nosotros sustituimos

2y + y = 14

3 años = 14

y = 14/3

y = 4.67 €

x = 14 € - y

x = 14 € - 4.67 €

x = 9.33 €

Por lo tanto,

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €
