Answer:

  125

Step-by-step explanation:

The value of x can be found by making use of the sum of angles of a hexagon.

__

<h3>angle sum</h3>

The sum of angles of an n-sided convex polygon is 180°(n -2). For a hexagon, which has 6 sides, the sum of angles is 180°(6 -2) = 720°.

__

<h3>setup</h3>

The listed angle values must total 720°.

 (x -30)° +(x +25)° +110° +115° +x° +x° = 720°

  4x° +220° = 720° . . . . . collect terms

__

<h3>solution</h3>

Subtract 220° to get the x-term by itself.

  4x° = 500°

  x = 125 . . . . . . . . divide by 4°

What is the solution to the system of equations below?
disa [49]

The solution to the system of equation are x=2, y=0, z=6

<h3>System of equations</h3>

System of equations are equations that contains unknown variables.


Given the equations

3x+y+2z=8

8y+6z=36

12y+2z=12

From equation 2 and 3

8y+6z=36 * 1

12y+2z=12 * 3

______________

8y+6z=36

36y+6z= 36

Subtract

8y - 36y = 36 - 36

-28y =0

y = 0

Substitute y = 0 into equation 2

8(0)+6z=36

6z = 36

z = 6

From equation 1

3x+y+2z =8

3x + 0 + 2(6) = 8

3x = 8 - 12

3x = 6

x = 2

Hence the solution to the system of equation are x=2, y=0, z=6

What’s the length of three pipes, when combined they equal 72m, how do I find the answer
allochka39001 [22]

Answer:

Each pipe is 24m

Step-by-step explanation:

<u>Given:</u>

  • three pipes
  • combined equal 72m
  • let the variable x represent the length of 1 pipe

<u>Algebraic Expression</u>:

3 pipes times length equals 72m (the total length)

3x = 72, we want x to be alone so divided both sides by 3

3x / 3 = 72 / 3

x = 24
