Answer:

Step-by-step explanation:

1. Set 3x + 20 and 5x - 50 equal to each other

3x + 20 = 5x - 50

3x = 5x - 70

-2x = -70

x = 34

2. Once you've solved for x plug that in to 3x + 20 or 5x + 50

3(35)+ 20

105 + 20

125

3. After plugging in the x take that answer and subtract from 180 which will give you y

180 - 125 = y

55 = y

Answer

<em>you</em><em> </em><em>can</em><em> </em><em>solve</em><em> </em><em>this</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>finding</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em>.</em><em> </em><em>here</em><em>,</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>x</em><em>=</em><em>3</em><em>5</em><em>a</em><em>n</em><em>d</em><em> </em><em>y</em><em>=</em><em>5</em><em>5</em><em>.</em>

Step-by-step explanation:

here, we have,

i)3x+20=5x-50[being vertically opposite angle]

20+50=5x-3x

70=2x

70/2=x

thus,x=35.

ii) 3x+20+y=180[being straight angle]

3×35+20+y=180

125+y=180

y=180-125

thus, y=55

<h2>hence, the value of x and y is 35 and 55.</h2>

Let  be the unknown number. Twice means times 2. So, the mathematical sentence should be .

Divide both sides by 2.

   

To remove the radical symbol, raise both sides to the second power.

 

Thus, the answer is 49. Twice the square root of 49 is equal to 14.

How do you divide $306 into the ratio of 9:5:3? Can someone give me some advice on how to solve this problem?
GarryVolchara [31]
In order to divide $306 into the ratio of 9 to 5 to 3, first you have to make each section of the ratio represented by a variable, and put it into an equation.

9x + 5x + 3x = 306

Our next step is to simplify the left side of the equation by combining all of the like terms, the ones that contain variables.

17x = 306

Finally, to solve this equation, you have to divide both sides by 17 to isolate the variable x on the left side of the equation.

x = 18

However, this is not our answer as it isn't in a ratio format and doesn't really make sense. To find our ratio, we have to multiply each of our initial numbers (9, 5, and 3) by our variable, x.

9 * 18 = 162
5 * 18 = 90
3 * 18 = 54

You can verify that these numbers are correct because if you add them together you get 306.

Your final ratio is 162:90:54.

Hope this helps! :)
