@Nnesha Do you think you can solve some more of them? :)

2. anonymous

and also, do I have to put every question in different posts, or can I put them all here? :)

3. Nnesha

substitute u for 20 x for 4 y for 7 and z for 10 then solve

4. Nnesha

well the rule is one question per post so other user will able to help you as wll

5. anonymous

so...20/10 + 4 times 7^2?

6. Nnesha

yep right!

7. anonymous

that would mean...198? Just making sure :)

8. Nnesha

hm how ?

9. anonymous

(20/10) 2 + 4 x 7^2 = 198

10. anonymous

Just making sure :)

11. Nnesha

$\frac{ 20 }{ 10+4(7)^2 }$

12. anonymous

20/10 = 2, 2 + 4(7)^2 = 198....thats how I got it.

13. Nnesha

wait $\frac{ u }{ z } +xy^2$ is this ur question ?

14. anonymous

Yep

15. Nnesha

ohhh okay then 198 is right i thought it's $\frac{ x }{ z+xy^2 }$

16. anonymous

Thanks then lol
