Part A 1/4 * 24 = elevation of D

OpenStudy (danieldjpon3):

ty

OpenStudy (danieldjpon3):

Now part B please

OpenStudy (danieldjpon3):

And i haev 1 more after this one :D

OpenStudy (danieldjpon3):

@Will.H Part B pls

OpenStudy (danieldjpon3):

Elevation of D is 6

OpenStudy (3mar):

Part B need to prove that you have got the elevation of city D relative to C one, so if C is below the sea level, accordingly D will be the same. That's it.

OpenStudy (danieldjpon3):

oh ok so is C under sea level?

OpenStudy (danieldjpon3):

Oh wait nvm im an idoit its 24

OpenStudy (danieldjpon3):

XD

OpenStudy (3mar):

No, it is not. " the elevation of city C is 24 feet above sea level", he said.

OpenStudy (danieldjpon3):

Ik

OpenStudy (danieldjpon3):

and D is 6 above sea level

OpenStudy (3mar):

Correct!

OpenStudy (danieldjpon3):

Ok ty

OpenStudy (3mar):

You are welcome!

OpenStudy (danieldjpon3):

Is that all for Part B?

OpenStudy (will.h):

Simplify 1/4 * 24 = D You'd get the answer positive why? Because positive multiplied by positive will be positive. That's all

OpenStudy (danieldjpon3):

ok ty
