Answer: x=8

Step-by-step explanation:

To solve for x, we want to use our algebraic properties to isolate x.

[tex]-\frac{1}{2}x-7=-11[/tex]            [add both sides by 7]

[tex]-\frac{1}{2}x=-4[/tex]                    [multiply both sides by -2]

[tex]x=8[/tex]

Now, we know that x=8.

#15

Answers

Step-by-step explanation:

82 + 76 + 42 = 200

42 out of 200 hmmm

200 / 2 = 100

42 / 2 = 21

21 out of 100 = 42 out of 200

=

21%

you first have to know the total number of responses: 82+76+42= 200
then you set up a proportion: %/100 = part/whole (and whichever thing you’re trying to solve for will be x)
so for this problem: x/100 = 42/200 (x is what you’re solving for: you’re trying to find the percent of people that prefer strawberry ice cream out of the 200 people surveyed)
then: cross multiply
i like to start with the x first so:
200 • x = 200x
and
42 • 100 = 4200
then finally put these together to make an algebraic equation: 200x = 4200
solve from there:
4200 divided by 200 (because you want x by itself) is 21 so you’re left with:
x = 21
now remember how we used x to represent the percent out of 100 on our proportion? this means that 21% of people (out of the 200) prefer strawberry ice cream
hope this helps!

A volcanic eruption releasing rock, ash, and dust particles into the air is an example of which interaction?

the biosphere interacting with the geosphere

the geosphere interacting with the atmosphere

the geosphere interacting with the hydrosphere

the hydrosphere interacting with the atmosphere

Answers

The interaction described is that of the geosphere interacting with the atmosphere.

The geosphere refers to all the rock and mineral materials that we have on our planet including:

Lava in the mantle Soil Mountains and everything made of rock

The atmosphere is the air that surrounds the Earth including gases like Nitrogen and Oxygen.

When a volcano erupts therefore, it is releasing rock (geosphere) into the air (atmosphere).

As a result, we can conclude that a volcano erupting is an interaction between the geosphere and the atmosphere.

Which part of the angle is the vertex?
A. AB
B. Point A
C. AC
D. Point C

Answers

Answer:

Point A

Step-by-step explanation:

The vertex is where the two rays meet together

A is the vertex

The vertex of the angle is the shared endpoint of the two rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], that is, the vertex is at Point A. Hence, option B is the right choice.

What is a ray?

A ray is made up of a half-line and its endpoint.

If a ray has an endpoint A and a B that is any other half-line point, then the ray is represented by  [tex]\underset{AB}{\rightarrow}[/tex].

What is an angle?

A pair of rays with a shared endpoint form an angle.

The rays are referred to as the angle's sides.

The shared endpoint is referred to as the angle's vertex.

How do we solve the given question?

We are asked to identify the vertex of the given anis

The given angle is made of the rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], the shared endpoint is at Point A.

As we know, the shared endpoint is the vertex of the angle, so Point A is the vertex of the given angle. Hence, Option B is the right choice.
