@jim_thompson5910

jimthompson5910 (jim_thompson5910):

your thoughts on it?

OpenStudy (dj3strella):

@jim_thompson5910 can u show me how to answer this problem?

jimthompson5910 (jim_thompson5910):

were you able to get anywhere with it? any ideas at all or anything crossed off the list?

OpenStudy (dj3strella):

nope

jimthompson5910 (jim_thompson5910):

for example, step 1 is the first step, so there is no way this is the conclusion (since that's the last line) So we can cross off choice C

jimthompson5910 (jim_thompson5910):

agreed or no?

OpenStudy (dj3strella):

yes @jim_thompson5910

jimthompson5910 (jim_thompson5910):

What is step 1. Go ahead and write that out.

OpenStudy (dj3strella):

is step 1. AC=BD?

jimthompson5910 (jim_thompson5910):

yes

jimthompson5910 (jim_thompson5910):

where else is that equation mentioned or listed?

OpenStudy (dj3strella):

Step #5

jimthompson5910 (jim_thompson5910):

step 5's equation is different from step 1

jimthompson5910 (jim_thompson5910):

AC = BD is listed somewhere else, but not in step 5

OpenStudy (dj3strella):

oh my bad i just nocited that

jimthompson5910 (jim_thompson5910):

where is AC = BD listed (other than step 1)?

OpenStudy (dj3strella):

i don't think anywhere else other then the proven area

OpenStudy (dj3strella):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

don't look in the table

jimthompson5910 (jim_thompson5910):

look above the table

jimthompson5910 (jim_thompson5910):

where is AC = BD listed (other than step 1)?

OpenStudy (dj3strella):

umm If AC=BD, then AB=CD

jimthompson5910 (jim_thompson5910):

yes, notice how it says "If AC = BD" the key here is that IF

jimthompson5910 (jim_thompson5910):

it all hinges on that

jimthompson5910 (jim_thompson5910):

the "if AC = BD" is known as a premise. It is a building block of an argument

jimthompson5910 (jim_thompson5910):

The assumption is that the premise is true which leads to the conclusion. So that's why the answer is choice A) true premises

OpenStudy (dj3strella):

because its true. If AC= BD is the first step

jimthompson5910 (jim_thompson5910):

because AC = BD is assumed to be true, it leads to the rest of the steps eventually leading to the conclusion

jimthompson5910 (jim_thompson5910):

if AC = BD isn't true, then the whole argument doesn't work

OpenStudy (dj3strella):

umm then idk what it would be

OpenStudy (dj3strella):

can you tell I don't understand this lol

OpenStudy (dj3strella):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

I just told you the answer

OpenStudy (dj3strella):

im sorry i had to go some where . and the answer is true premises

OpenStudy (dj3strella):

thank you @jim_thompson5910
