HI!!

4. misty1212

is it $\huge 8a+6(2b-7)$

5. anonymous

I think it's 54 frfr.....

6. misty1212

$8\times 5+6(2\times 3-7)$ is what you need to compute

7. anonymous

i thoght it was 33 or 90

8. misty1212

it is not 54 through

9. misty1212

lets take it step by step first we multiply inside the parentheses what is $$2\times 3$$?

10. anonymous

6

11. misty1212

ok so now we have $8\times 5+6(6-7)$ what is $$6-7$$?

12. anonymous

1

13. misty1212

hmmm er no

14. misty1212

$7-6=1$ but $6-7\neq 1$

15. anonymous

oops i ment to put this -1

16. misty1212

ok so now we are at $8\times 5+6\times (-1)$

17. misty1212

multiply next

18. anonymous

8 X 5 = 24

19. misty1212

???

20. anonymous

opps that is wrong

21. misty1212

yeah i think so too

22. anonymous

i ment 40

23. anonymous

sorry my keys have been acting up lately

24. misty1212

k we we are at $40+6\times(-1)$

25. anonymous

6 X (-1) = -6

26. misty1212

ok good, and $40-6=?$

27. anonymous

34

28. misty1212
