Question

need help with this

Answer 1

So do you see how AB and BC are equal to each other?

That means you just have to set the side lengths equal to each other and solve for 'x'

-x + 25 = 3(2x-8)

Answer 2

oh ok

Answer 3

i still kinda dont get it

Answer 4

So that line BD, it cuts the entire AC into two equal halves

which makes AB = BC

Answer 5

yeah i got that

Answer 6

but like the x how am i going to get x from that

Answer 7

so now all you have to do is solve for x

AB = -x + 25
BC = 3(2x-8)

so set them equal to each other

AB = BC
-x + 25 = 3(2x-8)

we want to get 'x' all by itself, so first distribute the 3 inside the parenthesis

remember
a(b - c) = ab - ac

so what is
3(2x - 8)

Answer 8

sorry man im a bit to slow for this a bit to much

Answer 9

when we have a number outside the parenthesis ( ), we have to multiply everything side with it so we can get rid of the ( )

so

Answer 10

we have to do the same thing for

3 (2x - 8) = ??

multiply the 3 with 2x
and the 3 with 8

Answer 11

6x and 24

Answer 12

Good!

so that means

3(2x - 8) = 6x - 24

does that make sense so far?

Answer 13

kinda

Answer 14

okay so now we went from

-x + 25 = 3(2x-8)

and then we distributed the '3' inside the parenthesis and we got

-x + 25 = 6x - 24

now we need to get 'x' all by itself

so that means we need to move the numbers to one side, and anything with 'x' on one side

so what do you get if you add 24 on both sides?

Answer 15

-x + 6x = 48?

Answer 16

careful, one step at a time

we have

-x + 25 = 6x - 24

if we add 24 on both sides we get

-x + 25 + 24 = 6x - 24 + 24

do you see how on the right side, the -24 + 24 will cancel out?

so we're left with

-x + 25 + 24 = 6x

so what is 25 + 24 = ??

48 isn't correct

Answer 17

yeah

Answer 18

sorry if im slow im trying to turn this in because its due in a bit

Answer 19

no worries

we have
-x + 25 + 24 = 6x

what is 25 + 24 = ??

Answer 20

48

Answer 21

no... use a calculator

Answer 22

49

Answer 23

there you go

so we have

-x +49 = 6x

now we want the 'x' to be all on one side so let's bring that -x to the other side

since it's a -x, we have to add 'x' on both sides

what do you get when you add x on both sides?

Answer 24

idk

Answer 25

what is

-x + x = ?

what is

6x + x = ?

Answer 26

2x and 7 x?

Answer 27

2x isn't right

remember it's negative x

-x + x

it's going to cancel out and be 0

Answer 28

oh ok

Answer 29

so now we have

49 = 7x

so now to get 'x' all by itself, you have to divide by 7

what is x?

Answer 30

7?

Answer 31

That's correct!

Answer 32

thx

Answer 33

You're welcome
