Answer:

60=2(20)+2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2(20)+2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).

Standard form equation that passes through (3,7) and (3,-6)
Fantom [35]

Answer:

  x = 3

Step-by-step explanation:

The standard form of the equation of a line is ...

   ax + by = c

For two points (x1, y1) and (x2, y2), this can be written as ...

  (y2-y1)x -(x2-x1)y = (y2-y1)x1 -(x2-x1)y1

  (7-(-6))x -(3-3)y = (7-(-6))3 -(3-3)(7)

  13x - 0y = 13·3

Standard form requires no common factors among the constants, so ...

  x = 3

Find the value of x. Give reasons to justify your solution. b ∈ ac, d ∈ fa
tatiyna

Answer:

x = 27

Step-by-step explanation:

∠ ABD and ∠ BDE are alternate angles and are congruent, then

∠ BDE = 72°

∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is

2x + 72 + 2x = 180

4x + 72 = 180 ( subtract 72 from both sides )

4x = 108 ( divide both sides by 4 )

x = 27
