Answer:

<h3>The value of the second number is 24 and the first no 12.</h3>

Step-by-step explanation:

<h3> Greetings !</h3>

From, the given word explanation try to create your own equation like

x + y = 36... (1) let the two numbers be x and y respectively.
2x = y ....(2) let x be the first no and it's twice that of the second number.

From, equation (1) solve for x

x + y = 36
x = 36-y... (3)

Substitute, equation (3) to equation (2).

2(36-y) =y
72 - 2y =y
72 = y + 2y.... solve for y
72 = 3y.... divide both sides by 3
72/3 = y..
y=24 ...simplified

Answer: 24+12=36

Step-by-step explanation:

36= _+_

2x(2 times)

X+2x=36

3x=36

12+2(12)=36

12+24=36

If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m

nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

$2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17$

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

$\angle1=2(17)+6\\\angle1=34+6\\\angle1=40$

So, the actual measure of ∠1 = 40°
