Answer: 6

Explanation: To multiply a whole number times a fraction such as 9 · 2/3, think of 9 as 9/1 so we have 9/1 · 2/3.

Now we simply multiply across the numerators and across the denominators.

9 · 2 is 18 and 1 · 3 is 3 so we have 18/3.

18/3 simplifies to 6.

So 9 · 2/3 is 6.

A, B, and C are collinear points. B is between A and C. AB = 5x + 8 BC = 6x - 1 AC = 12x - 11 Find AC.
Vlada [557]

Answer:

AC = 198

Step-by-step explanation:

Since all these points are collinear, we know that the addition of AB plus BC should give the same as AC. We can then set an equation that addresses this identity:

AB + BC = AC

5x +8 +6x - 1 = 12x - 11

Now re-arranging like terms in order to combine them:

8 - 1 + 11 = 12x - 5x - 6x

19 - 1  = 12x - 11x

18 = x

Now that we know the value of 'x", we can determine the value of AC:

AC = 12x - 11

AC = 12 (18) - 11

AC = 216 - 18

AC = 198

Por una calculadora y un cuaderno habríamos pagado, hace tres días, 10,80 €. El precio de la calcula-dora ha aumentado un 8%, y
Inessa05 [86]

Answer:

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.

Step-by-step explanation:

A partir del enunciado podemos construir el sistema de ecuaciones lineales:

Hace tres días:

x+y = 10.80 (1)

Actualmente:

1.08\cdot x + 0.9\cdot y = 11.34 (2)

Donde:

x - Precio de la calculadora.

y - Precio del cuaderno.

Por métodos algebraicos, tenemos que el sistema de ecuaciones tiene la siguiente solución:

x = 9, y = 1.8

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.
