\sf\purple{The\:value\:of\:x\:is\:4.} ✅

<u>Step-by-step </u><u>explanation</u>:-

3x - 3 = 9 \\ ➡ \: 3x = 9 + 3 \\ ➡ \: x =  \frac{12}{3}  \\ ➡ \: x = 4

<u>To </u><u>verify</u>:-

3 \times 4 - 3 = 9 \\ ➵ \: 12 - 3 = 9 \\ ➵ \: 9 = 9 \\ ➵ \: L.H.S.=R. H. S

Hence verified.

\circ \: \: { \underline{ \boxed{ \sf{ \color{green}{Happy\:learning.}}}}}∘

Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH re
Mkey [24]

the picture in the attached figure

Step 1

Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

P=AD+DC+CB+BA\\P=3+2+2+4\\ P=11 in

Step 2

Find the scale factor

if Quadrilateral ABCD is similar to Quadrilateral EFGH

then

PerimeterEFGH=PerimeterABCD*scale factor

scale.factor=\frac{EF}{AB} \\ \\ scale.factor=\frac{60}{4} \\ \\ scale.factor=15\frac{ft}{in}

Step 3

Find the perimeter of the actual walkway (Quadrilateral EFGH)

PerimeterEFGH=PerimeterABCD*scale factor

PerimeterEFGH=11*15

PerimeterEFGH=165 ft

therefore

the answer is

165 ft

Find the sum.<br> 2(-5y+6)+(2y-8)
kotegsom [21]

Answer: I am just hoping that this is the correct answer

Step-by-step explanation:

2(-6 + -5y) + (2y + -8) = 0

(-6 * 2 + -5y * 2) + (2y + -8) = 0

(-12 + -10y) + (2y + -8) = 0

Reorder the terms:

-12 + -10y + (-8 + 2y) = 0

Remove parenthesis around (-8 + 2y)

-12 + -10y + -8 + 2y = 0

Reorder the terms:

-12 + -8 + -10y + 2y = 0

Combine like terms: -12 + -8 = -20

-20 + -10y + 2y = 0

Combine like terms: -10y + 2y = -8y

-20 + -8y = 0

Solving

-20 + -8y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '20' to each side of the equation.

-20 + 20 + -8y = 0 + 20

Combine like terms: -20 + 20 = 0

0 + -8y = 0 + 20

-8y = 0 + 20

Combine like terms: 0 + 20 = 20

-8y = 20

Divide each side by '-8'.

y = -2.5

Simplifying

y = -2.5
