Answer 4

find the value of x and y

Answer 5

are the two triangles proportional

Answer 6

I'd think so

Answer 7

ok is 3x+2y the length of the whole side or just that half?

Answer 8

half

Answer 9

hmmm... good point

Answer 10

shoot I was looking for ratios and... wasn't finding much hehehe

Answer 11

me too i think...like 3x-2y+8/5x-3y=8/7

Answer 12

and then 3x-2y=8

Answer 13

and then solve for x and make those equations equal eachother

Answer 14

... so you'd end up with a system of equations

Answer 15

ohh I see... substitute... right

Answer 16

yeah...im just not sure if that is right

Answer 17

Answer 18

@myininaya

Answer 19

\(\bf 3x-2y=8\implies y=\cfrac{3x}{2}-4\\ \quad \\
\cfrac{7}{5x-3y}=\cfrac{1}{2}\implies \cfrac{7}{5x-3\left(\cfrac{3x}{2}-4\right)}=\cfrac{1}{2}\\ \quad \\
14=5x-3\left(\cfrac{3x}{2}-4\right)\implies 14=5x-\cfrac{9x}{2}+12\)

Answer 20

if 8 is half, the other half is 8, thus 8/16 = 1/2

Answer 21

i got y=2 and x=4..

Answer 22

yeap

Answer 23

since x = 4, you can just plug that back in \(\bf y=\cfrac{3x}{2}-4\)

Answer 24

yeah thanks

Answer 25

yw

Answer 26

hmm y = -1 btw, after plugging it in

Answer 27

x = 4, yes....

Answer 28

ohh wait.... dohh.. yes is 2, nevermind =)
