Juanita wants to model the equation 3x+2 = -x+ 6. she begins with the tiles below.
how can juanita complete her model?

put 4 yellow unit tiles on the left side of the equal sign.
put 4 yellow unit tiles on the right side of the equal sign.
put 6 green x-tiles on the right side of the equal sign.
put 6 yellow unit tiles on the right side of the equal sign.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

the correct option is b

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
