Answer:

x = 37

Step-by-step explanation:

i just check it with a protractor, if 37 is the answer then that means " (4x - 20) degrees" is 143.

143 + 37 = 180

i think the answer is probably x = 37

Which graph represents the solution set for the inequality StartFraction one-half EndFraction x is less than or equal to 18.x ≤
Mrrafil [7]

Answer:

A number line from 0 to 60 in increments of 6. A point is at 36 and a bold line starts at 36 and is pointing to the left. ⇒ last answer

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- <u><em>When solving an inequality, there are some important points:</em></u>

# If the inequality is x > a, then it represented on the number line by

  a ray with empty small circle as end starts at a and pointed to

  the right (⇒ ∞)

# If the inequality is x ≥ a, then it represented on the number line by

  a ray with bold small circle as end starts at a and pointed to the

  right (⇒ ∞)

# If the inequality is x < a, then it represented on the number line

  by a ray with empty small circle as end starts at a and pointed to

  the left (⇒ -∞)

# If the inequality is x ≤ a, then it represented on the number line by

  a ray with bold small circle as end starts at a and pointed to the

  left (⇒ -∞)

* <em>Lets solve the problem</em>

∵ 1/2 x ≤ 18

- Multiply both sides by 2

∴ x ≤ 36

- To represent it draw a number line from 0 to 60 and the counted

 by 6 as 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60

- Draw a ray with bold end starts at 36 and pointed to the left

∴ A number line from 0 to 60 in increments of 6. A point is at 36 and

  a bold line starts at 36 and is pointing to the left.

Set up a proportion and use it to convert an angle of 225° into radians
Stels [109]
180° = π radians

1° =      (π/180) radians

225° =  225*(π/180) = 1.25π radians
 
                              ≈ 3.927 radians   <span />

vivado [14]
2(x - 1) - (3x - 2) 

First, simplify brackets. / Your problem should look like: 2(x - 1) - 3x + 2
Second, expand. / Your problem should look like: 2x - 2 - 3x + 2
Third, gather like terms. / Your problem should look like: (2x - 3x) + (-2 + 2)
Fourth, simplify. / Your problem should look like: -x

Answer: -x
