Hey Leila :)
Welcome to OpenStudy!

The first one should be pretty straight forward.
This symbol > means greater than.
So the equation reads "y is greater than 1.9".

They want to know what number you could put in place of y for the equation to hold true. Well, B is certainly not the correct option. -2 is NOT greater than 1.9.

The same goes for option D, 1.9 is NOT strictly larger than 1.9.

zepdrix · Answer

The other problems require a little bit of algebra.

g+3 > 6

If we isolate the g, it might be easier to see what's going on.
Right now 3 is being added to g,
so to isolate g, we'll do the opposite,
we'll subtract 3 from each side,

g+3-3 > 6-3

giving us

g > 3

So again, choose the option which could take the place of g and make the equation hold true.

I'm confused. So 1. is either A or C? And 2. is A?

zepdrix · Answer

g > 3

So you think maybe option A, g=3.

3 > 3

Hmm no that doesn't work out. 3 is not larger than 3.

zepdrix · Answer

Yes, number 1 is either A or C.
Use your brainnnn powerrrrr :D

leilatheunicorn · Answer

So 4, which is B?

zepdrix · Answer

Mmmm ya that looks better!

leilatheunicorn · Answer

And 2. is 2 (c)?

zepdrix · Answer

problem 1 is C) 2.
yes.

I think that's what you meant at least.

leilatheunicorn · Answer

Yes that's what I mean :)

zepdrix · Answer

Problem 3 is a little tricky.
$\large\rm 6 > \color{indianred}{z}(10-\color{indianred}{z})$

You wouldn't want to try and solve for z in this case.
It would be pretty difficult.

Instead plug the options in, one by one,
and see which one gives you a true equation.

Example:
If I plug option D which is 3,
$\large\rm 6 > \color{indianred}{3}(10-\color{indianred}{3})$
Then it will simplify to,
$\large\rm 6 > 3(7)$
$\large\rm 6 > 21$

This reads as "6 is greater than 21".
Which is not true.

So option D is no bueno.
