Hello - let's do this step by step. Show your work.

You're asking: 9(8−x)=3x.

Now, simplify both sides of the equation.

9(8−x)=3x

(9)(8)+(9)(−x)=3x (To do that, distribute)

72+−9x=3x

−9x+72=3x

Now,  subtract 3x from both sides.

−9x+72−3x=3x−3x

Simplify,

−12x+72=0

After, subtract 72 from both sides.

−12x+72−72=0−72

−12x=−72

Last thing, divide both sides by -12.

-12x/12 = -72/-12

Divide.

Therefore, you have <u>x = 6</u> as your final answer.

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
Anika [276]

Answer:

Step-by-step explanation:

Triangle GEF is a right angle triangle.

From the given right angle triangle

GE represents the hypotenuse of the right angle triangle.

With ∠E as the reference angle,

FE represents the adjacent side of the right angle triangle.

FG represents the opposite side of the right angle triangle.

To determine tan E, we would apply the tangent trigonometric ratio

Tan θ = opposite side/adjacent side. Therefore,

Tan E = 56/33

Tan E = 1.69697

It becomes 1.70 to the nearest hundredth.
