Angles ABC and DBE are vertical angles, with angle ABC = 4x, and angle DBE =( 2x+18)
Dmitrij [34]
 V<span>ertical angles are equal.
We have 4x = 2x + 18.
Then, 2x = 18;
x = 18 </span>÷ 2;
x = 9 degrees;
The measure of angle DBE is 2 × 9 + 18 = 36 degrees.

¿Cual es el número cuya tercera parte más 12 da 26?<br>OK​
iren2701 [21]

Answer:

42

subtract 36 on both sides

x=42

   

42/3=14

14+12=26

Point N is on line segment MO. Given MN = x, MO = 3x - 6,
finlep [7]

Answer:

Step-by-step explanation:

N is between points M and O

MN = x

MO = 3x - 6

NO = x + 1

The way it reads MN + NO = MO

x + x + 1 = 3x - 6

2x + 1 = 3x - 6

2x - 2x +1 = 3x -2x - 6

1 = x - 6          

1 + 6 = x

x = 7

MO = 3x - 6

MO = 3*7 - 6

MO = 21 - 6

MO = 15

Convert 59 degrees in Fahrenheit to Celsius temperature using the formula F=9/5c+32.
nataly862011 [7]

Answer:

15° C.

Step-by-step explanation:

To do this, we will need to plug in and solve.

59 = 9/5c + 32

Isolate the variable by subtracting 32 by both sides:

27 = 9/5c.

Divide both sides by 9/5, giving you:

15° C.
