= 18-27x-29= 8x-x+23
= -11-27x= 7x+23
= -27x-7x= 23+11
= -34x= 34
= x= -1

Hello There!

Remember the exterior angle of a triangle is equal to the opposite interior angles of a triangle

137-x=2x+3x-1

now we can solve for x

step 1 combine like terms

2x+3x=5x

now we have

137-x=5x-1

step 2 add 1 to each side

-1+1 cancels out

137+1=138

138-x=5x

step 2 add x to each side

-x+x cancels out

5x+x=6x

now we have

138=6x

step 3 divide each side by 6

6x/6=x

138/6=23

we´re left with x=23

Joan has 1/2 yard of felt. She will use 1/3 of it to make place cards. How much felt will she will use for place cards?

-Dominant- [34]

ANSWER

$\frac{1}{6} \: yards$

EXPLANATION

It was given that, Joan has

$\frac{1}{2} \: yard \: of \: felt$

and she will use

$\frac{1}{3}$
of it to make place cards.

We want to find how felt she will use for place cards.

We just have to find,

$= \frac{1}{3} \: of \: \frac{1}{2}$

$= \frac{1}{3} \times \frac{1}{2}$

$= \frac{1}{6}$

Therefore Joan will use

$\frac{1}{6}$

yards of felt for the place cards.
