Kareem and Christine each ran every day as part of an exercise routine. Kareem ran 5 miles each day for x days. Christine ran 6

stellarik [79]

$5x \geq 6y$
The inequality above shows the relationship.

In this case, Kareem miles on the left have to be at least as much as Christine's on the right.

It would read: 5x is greater than or equal to 6y.

£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
