Answer:

angle AOD = 90⁰

BOD = 3x⁰

90⁰+3x⁰ = 180⁰( being straight angle)

3x = 180⁰-90⁰

3x = 90⁰

x = 90⁰/3

x = 30⁰

now

y⁰+139⁰ = 180⁰(being straight angle)

y⁰ = 180⁰-139⁰

y⁰ = 41⁰

Step-by-step explanation:

\frac{x}{x + x + 6}  =  \frac{9}{30}

\frac{x}{2x + 6}  =  \frac{9}{30}

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6

I do not know what to put and this was due yesterday
atroni [7]

Answer:

Your answer will be x=2

Step-by-step explanation:

Five plus 6 times a number is equal to 21 minus 2 times the number

Your equation is this:

5+6x=21-2x

Subtract 6x from both sides

5+6x-6x=21-2x-6x

5=21-8x

subtract 21 on both sides

5-21=21-21-8x

-16=-8x    Divide -8 on both sides

2=x

Hope this helps :)

Answer:

  C.  96 ft³

Step-by-step explanation:

The area of the triangular base is ...

  A = 1/2bh

  A = 1/2(6 ft)(8 ft) = 24 ft²

Then the volume is ...

  V = 1/3Bh . . . . . where B is the base area and h is the height

  V = 1/3(24 ft²)(12 ft) = 96 ft³ . . . . volume of pyramid

What is 3t – 6 = t –2.
GenaCL600 [577]

Answer:

t=2

Step-by-step explanation:

<em>3</em><em>t</em><em>-</em><em>6</em><em>=</em><em>t-2</em><em>(</em><em>Group</em><em> </em><em>like </em><em>terms</em><em>)</em>

<em>3</em><em>t</em><em>-</em><em>t</em><em>=</em><em>-</em><em>2</em><em>+</em><em>6</em>

<em>2</em><em>t</em><em>=</em><em>4</em><em>(</em><em>Divide</em><em> </em><em>both </em><em>sides </em><em>by</em><em> </em><em>4</em><em>)</em>

<em>t</em><em>=</em><em>2</em><em>(</em><em> </em><em> </em><em>This</em><em> </em><em>is </em><em>because</em><em> </em><em>when</em><em> </em><em>you </em><em>divide </em><em>both </em><em>sides </em><em>by </em><em>2</em><em>,</em><em> </em><em>2</em><em> </em><em>can</em><em> </em><em>divide </em><em>4</em><em> </em><em>2</em><em> </em><em> </em><em>times</em><em> </em><em>so</em><em> </em><em>that's</em><em> </em><em>why</em><em> </em><em>we</em><em> </em><em>have</em><em> </em><em>t</em><em> </em><em>as</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>2</em><em>)</em>
