Vocaloid (vocaloid):

well, it says that point S is between R and T so RT = RS + ST

Vocaloid (vocaloid):

60 = 3x - 16 + 4x - 8 the first step is to solve for x, do you think you can take it from here?

OpenStudy (anonymous):

hold i'll do it then see if im correct

OpenStudy (anonymous):

x=12?

Vocaloid (vocaloid):

yup, that's the first step. now that we know what x is, we can now find RS and ST RS = 3x - 16 = ? ST = 4x - 8 = ?

OpenStudy (anonymous):

doin it hold on

OpenStudy (anonymous):

rs is 24

OpenStudy (anonymous):

st is 40

Vocaloid (vocaloid):

check rs again. st is right

Vocaloid (vocaloid):

3(12)-16 = ?

OpenStudy (anonymous):

lol sorry 20

Vocaloid (vocaloid):

yeah.

Vocaloid (vocaloid):

problem #30 is basically the same thing, do you wanna give it a shot?

OpenStudy (anonymous):

k

OpenStudy (anonymous):

OpenStudy (anonymous):

rs i got 6

okY

Vocaloid (vocaloid):

AD = 12, so let's mark that right away|dw:1440113728465:dw|
