Answer: D-18 years, Joan-41 years

Step-by-step explanation:

Given

The Sum of Debbie and Joan's age is 59

Take x and y as the age of Debbie and Joan

In 5 years, twice Debbie's age will be equal to Joan's age

\Rightarrow 2(x+5)=y+5

\Rightarrow 2x+10=y+5\\\Rightarrow 2x-y=-5

Also, x+y=59

solving these two equations we get

\Rightarrow x=18;y=41

Es un número disminuido en cuatro su resultado es ocho
NARA [144]

Resolviendo una resta, veremos que el número es igual a 12.

<h3>¿Como encontrar el número?</h3>

Definamos X como nuestro número, sabemos que cuando este número es disminuido en cuatro (es decir, le restamos 4 a nuestro número X) el resultado es 8.

Entonces, lo que tenemos que hacer es resolver la operación:

X - 4 = 8

Para resolver esto, lo que tenemos que hacer es sumar 4 en ambos lados de esta ecuación, asi obtenemos:

X - 4 + 4 = 8 + 4

X = 12

De esta forma, concluimos que nuestro número es igual a 12.

jasenka [17]
There are several information's of immense importance in the problem. Based on these information's the answer to the question can be easily reached. The only thing that has to be kept in mind is the calculation part, otherwise it is a simple problem.
Now it is given that:
A large chocolate shake takes 8/9 of a pint of milk.
Then
Amount of milk required to make medium shake = (8/9) * (1/7) of a pint
                                                                              = 8/63 of a pint
Then it can be said that for making a medium chocolate shake , 8/63 of a pint of milk is required. This is the simplest form of the fraction and it cannot be expressed as a mixed number since the denominator is higher than the numerator.
