2. psi9epsilon

15

3. ashleylynn

can u explain why 15? cause i dont understand on how to figure this out

4. psi9epsilon

8-(-7)

5. psi9epsilon

A IS AT -7 AND D IS AT +8, we want distance AD = 8-(-7)

6. ashleylynn

ohkay thanks there's a couple of these that i have to do and i suck at math it makes me panic hahaha

8. ashleylynn

If EF = 6 and EG = 21, find the value of FG. The drawing is not to scale.

9. ashleylynn

10. TheMind

to find the distance, always take the absolute value

11. ashleylynn

which is ?

12. psi9epsilon

eg= ef+ fg should help you out : )

13. ashleylynn

so 15?(:

14. TheMind

yes

15. ashleylynn

What segment is congruent to segment_AC?

16. psi9epsilon

first find AC = 6, units similarly find be = 4-(-2), since they are equal that should give you the answer

17. ashleylynn

so the anwer is BE

18. psi9epsilon

aha

19. psi9epsilon

i am not allowed to give you correct answers

20. psi9epsilon

explained the method

21. ashleylynn

ohkayyy fair enoughhh

22. ashleylynn

If Z is the midpoint of segment_RT, what are x, RZ, and RT?

23. ashleylynn

24. psi9epsilon

midpoint divides segment in two equal parts i.e RZ=ZT so 4x-28=24

25. psi9epsilon

sovle for x

26. psi9epsilon

does that give you answers

27. ashleylynn

I had to restart my computer it froze and I am doing it right now. (:

28. ashleylynn

ohkay i got X

29. ashleylynn

@psi9epsilon

30. psi9epsilon

so what is value of X you may have obtained ?

31. ashleylynn

x=13

32. psi9epsilon

great , now use that value of x in the equation 4x-28 to obtain the values

33. ashleylynn

I got -27?

34. psi9epsilon

nope, it should be 4*13-28

35. ashleylynn

Opps I see that I did wrong, Now I got 24.

36. psi9epsilon

should be correct

37. ashleylynn

Ohkay so is that for RZ? or RT?

38. ashleylynn

?

39. psi9epsilon

rz=zt, value of 24 = rz, and rt= rz+zt

40. ashleylynn

Wait I am lost how do I get the value of ZT?

41. ashleylynn

Just kiddding I got it it's 28.
