Answer:

irrational

Step-by-step explanation:

A rational number is one that can be written as the ratio of two integers. For example 3=3/1, −17, and 2/3 are rational numbers.So in that case 2/3 is irrational.

Answer:

Measure 1 is 112º

You know that 112º is the closest answer because you can see the angle is obtuse. And obtuse is an angle less than 180 but more than 90º

Step-by-step explanation:

So a straight line is equal to 180º so just set the equations equal to 180. Your final equation should look like (3x + 22) + (2x + 8) = 180

Now all you have to do is solve for x.

3x + 22 + 2x + 8 = 180

Combine like factors

3x + 2x = 5x

22 + 8 = 30

Now your equation should look like 5x + 30 = 180

Subtract 30 from both sides.                   -30       -30  

                                                                            ----------

                                                                                150

So now the equation should look like 5x = 150

Divide both sides by 5, 150/5 = 30

SO x = 30

Plug 30 in to the equation to check your answer

(3*30 + 22) = 112

(2*30 + 8) = 68

112 + 68 = 180

Answer:

-18w+2

Step-by-step explanation:

6*-3w=-18w

1/3*6=2

The resultant expression is -18w + 2 which could represent the expanded form by using the distributive property.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question as follows:

6(-3w+1/3)

We have to expand the given expression by using the distributive property.

As per the question, we have

⇒ 6(-3w+1/3)

Apply the distributive property of multiplication,

⇒ 6 × (-3w)+ 6 × (1/3)

⇒ -18w + 6/3

⇒ -18w + 2

Therefore, the resultant expression is -18w + 2.

Step-by-step explanation:

-6x + 10 = -104

-6x = -114

x = 19

Answer:

[tex]\boxed {x = 19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

-[tex]6x + 10 = -104[/tex]

-Subtract [tex]10[/tex] to both sides:

-[tex]6x + 10 - 10 = -104 -10[/tex]

-[tex]6x = -114[/tex]

-Divide both sides by [tex]6[/tex]:

[tex]\frac{-6x}{-6} = \frac{-114}{-6}[/tex]

[tex]\boxed {x = 19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]19[/tex].

The points of concurrency of a triangle include the following:

A triangle can be defined as a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.

In Geometry, there are different types of triangle based on the length of their sides, vertices and angle, these include;

A point of concurrency refers to a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when three (3) or more lines intersect at a single point.

Answer:

See below

Step-by-step explanation:

For there to be infinitely many solutions, the equations have to be the same on the left side of the equation as on the right

3x+6  = 3 ( x+2)

As you can see when we distribute

3x+6  = 3x+6

Another example

2x+3 = x+ x+ 1+2

When we combine like terms

2x+3 = 2x+3

A third example

2x -5 +2x -6 = 7x-3x - 15+4

Answer:

2:25 pm

Step-by-step explanation:

If you look at the diagram of the clock I put, the blue hands are the starting times and the red are the ending times. The short arrow shows the hours so we move that four numbers clockwise (to the right). The long arrow shows minutes so we move it two numbers clockwise since inbetween each number is 5 minutes and we need to go 10 minutes. We switch the am to pm since the shorter arrow moves past the 12.

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

[tex]s = 10|x - 4| + 50[/tex]

Required

Solve for x when s = 80

Substitute 80 for x

[tex]80 = 10|x - 4| + 50[/tex]

Subtract 50 from both sides

[tex]80 - 50= 10|x - 4| + 50 - 50[/tex]

[tex]30= 10|x - 4|[/tex]

Divide through by 10

[tex]\frac{30}{10}= \frac{10|x - 4| }{10}[/tex]

[tex]3= |x - 4|[/tex]

Reorder

[tex]|x - 4| = 3[/tex]

This can be split into

[tex]x - 4 = 3[/tex] or [tex]x - 4 = -3[/tex]

Solve for x

[tex]x = 4 + 3[/tex] or [tex]x = 4 - 3[/tex]

[tex]x = 7[/tex] or [tex]x = 1[/tex]

Hence:

The numbers of measure of music played are 1 and 7
