Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so

-150x<u>></u>-2400
divide both sides by -150
flip sign
<u />x<u><</u>16



-336<u>></u>-21y
divide both sides by -21
flip sign
16<u><</u>y

they seem to have the same solution

x=y<u>></u>16

-150x>_ -2400

Divide both sides by -150

-150x/-150>_ -2400/-150

x<_ 16


-336>_ -21y

Flip the equation

-21y<_-336

Divide both sides by -21

-21y/-21<_ -336/-21

y>_ 16


I hope that's help !

Mark and Henry win some money and share it in the ratio 1:3. Mark gets £9. How much did Henry get?
Fed [463]

Answer:

Hope this helps!!!!!!

Mark Brainlest!!!!!!!!!!

Step-by-step explanation:

Mark and Henry win some money and share it in the ratio 1:3. Mark gets £9. How much did Henry get?

Ratio = 1 : 3

Let Mark's share be 1x = x

and Henry's share be 3x

We know that Mark gets £9

So,

1x = x = £9

Then 3x = £(3 * 9) = £27

HENCE,

Mark's share = £9

Henry's share = £27

Total money = Mark's share + Henry's share = £9 + £27 = £36
