Bas_tet [7]4 years ago

The total is 90°. Set the equation

8x - 6 + 80 = 90

Simplify. Combine like terms

8x + 74 = 90

Isolate the x. Do the opposite of PEMDAS. What you do to one side, you do to the other

8x + 74 (-74) = 90 (-74)

8x = 16

8x/8 = 16/8

x = 2

2 is your answer for x

hope this helps

You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2

Use the Side-Splitting Theorem to find the value of x.
spin [16.1K]
<h2>The required "option D. 9.6" is correct.</h2>

Step-by-step explanation:

In given figure,

AD = x, DB = 12, BE = 8 and EC = 10

To find, the value of x = ?

Use the Side-Splitting Theorem,

We know that,

\dfrac{AD}{DB} =\dfrac{BE}{EC}

⇒ \dfrac{x}{12} =\dfrac{8}{10}

⇒ x =\dfrac{8 \times 12}{10}

⇒ x = \dfrac{96}{10}

⇒ x = 9.6

∴ The value of x = 9.6

Thus, the required "option D. 9.6" is correct.

Cans some one help this stinks so bad.
Darya [45]

Answer:

5,652,000

Step-by-step explanation:

1. Simplify 1/3 * 3.14

you'll end up with 3.14/3

2. Divide 3.14 by 3

this will give you 1.046

3. Raise 150 to the power of 2.

you now have 22,500

your equation is now: 1.046 * 22,500 * 240

4. Multiply 1.046 by 22,500

your equation is now 23,500 * 240

5. Multiply 23,500 by 240

your answer is 5,652,000

What value of x is in the solution set of 2(3x - 1) = 4x - 6?
Viefleur [7K]

Answer:

-2.5 = x

Step-by-step explanation:

Multiply by what's in the parentheses by 2.

6x - 1 = 4x - 6

Add 6 to both sides of equation.

6x + 5 = 4x

Subtract 6x from both sides.

5 = -2x

Divide both sides by -2.

-2.5 = x
