1. anonymous

What's this???

2. anonymous

i dont know...thats what the problem looks like on my page....

3. anonymous

what's the instruction of this question at the top of the page ?

4. anonymous

Find a value of the variable that shows that the two expressions are not equivalent. Answers may vary.

5. anonymous

Put a = 1

6. anonymous

so then it would make the problem 8/7

7. anonymous

The first one becomes 8/7 and the second 1 Put a = 2 and u get 9/7 and 2

8. anonymous

how would i show my work for that?

9. anonymous

???????

10. anonymous

First expression is a+7 ---- 7 Putting a=1, we get 1+ 7 ie 8/7 ----------- (A) ---- 7 The second expression is a Putting a= 1 , we get a = 1 --------------(B) From (A) and (B) we can see that the first expression is not equal to the second.

11. anonymous

Similarly by replacing a by 2 in the two expressions you will get 9/7 ---- (A) and 2 ------ (B) Hope it is clear now??

12. anonymous

13. anonymous

See, you have to show that the two expressions are not equivalent, that is values of a + 7 and a are not equal/equivalent ----- 7

14. anonymous

So from (A) u hv a + 7 8 ----- = --- 7 7 and From (B) a = 1 So their values are not equivalent

15. anonymous

Is it clear now???

16. anonymous

....mmmm ok

17. anonymous

sorry im really stupid when it comes to math....

18. anonymous

Pls don't use the term stupid NOBODY in this world is stupid Its only that some people r lucky to get teachers who explain concepts nicely and clearly The unlucky ones do not get good teachers and hence their concepts r not clear

19. anonymous

and it doesnt help that its an online class...:( oh well...im still learning...

20. anonymous

Well even online classes can be good I teach a kid in America online and make sure he gets the concepts

21. anonymous

We do more examples if required

22. anonymous

I think my brain is fried for the night...im going to email my instructor for additional help...ill be back though to learn more concepts of math! thanks though!

23. anonymous

U r welcome anytime...
