Answer 30

what question is needed?

Answer 31

What do you mean? Both the questions are the same. I am just not sure what to do after this point, to get the answer, and I have been in this test for an hour and I haven't even done the first question.

Answer 32

ok . one moment please....

Answer 33

Ok, I really hate disappointing people but I just had a total brain fart and unfortunately cant answer this problem. Sorry :(

Answer 34

The easiest way to do these is pick out the biggest number out of the 3 numbers.
then make sure the other 2 add up to a *bigger* (not just equal) number.

Answer 35

What do you mean?

Answer 36

@rebeccaxhawaii

Answer 37

just plug in your numbers into that formula

Answer 38

how?

Answer 39

plug a for a
plug in b for b
and plug in c for c

Answer 40

110>40
115>35
75>75

Answer 41

is 110 greater than 40?
is 115 greater that 35?
is 75 greater than 75?

Answer 42

yes
yes
equal

Answer 43

so thats not the choice because 75 is not greater than 75

so just do that for each option and you will eventually find one that fits
good luck

Answer 44

Okay, thanks!

Answer 45

@rebeccaxhawaii So am I looking for all the answers to be yes? Or equal?

Answer 46

no > means greater than not equal
= means equal

Answer 47

No what I mean is when you asked me if 110 was greater than 40, and I said yes, when I have the greater formula am I looking for it to be equal or no?
