£90 is divided between Mark, Henry & Gavin so that Mark gets twice as much as Henry, and Henry gets three times as much as G

Phantasy [73]

Answer:

Mark gets £54

Step-by-step explanation:

Let Gavin share=x

Henry=3x

Mark=2(3x)

x+3x+2(3x)=£90

x+3x+6x=£90

10x=£90

x=9

Gavin=x=£9

Henry=3x

=3(9)=£27

Mark=2(3x)

=2(3*9)

=2(27)

=£54

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,

Serggg [28]

Answer:

Step-by-step explanation:

he value of K would be 2 because the function f(x) is the equation of a line. K is represented as the y-intercept. When a line is shifted down 2 units, the y-intercept also gets shifted down 2 units. In f(x) the y-intercept is zero. So the difference would be 2 units

The Soup Shack usually makes tomato soup with 999 tomatoes for every 121212 bowls of soup. Today, they made 888 bowls of soup wi

marin [14]

Answer:

Same quanitity.

Step-by-step explanation:

The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 bowls of soup.

Today, they made 8 bowls of soup with 6 tomatoes.

We need to compare today's soup to the usual recipe.

For 9 tomatoes for every 12 bowls of soup = $\dfrac{9}{12}=\dfrac{3}{4}$

For 8 bowls of soup with 6 tomatoes = $\dfrac{6}{8}=\dfrac{3}{4}$

It means we can see that both the soup has the same quantity. Hence, this is the required solution.
