Answer 1

Answer:

Step-by-step explanation:

There is 8 on one side and 2a + 2 on the other so we can eliminate answer D.
8=2a+2

We take away 2 from both sides getting a on one side. So 6=2a. To find a we do the inverse way to solve the equation. To get 6 we multiply "a" by 2. To get "a" we dp 6/2 = 3. boom a=3 so C is your answer

Answer 2

Answer:
C
Explanation:
The answer is 3 because if one side is 8 and you have 2 on one side you do 8-2 which is 6. Since you have 2 a’s you do 6 divide by 2 which is 3. This means that the answer is c

The length of a line segment is 8 units.one end point is p(5,-3). which of these could be the other endpoint of the line segment?

A(-3,-3)

B(-3,-11)

C(5,8)

D(8,-3)

Answers

Answer:

Step-by-step explanation:

Solution

Distance between two points =

(x 2−x 1) 2+(y 2 −y 1) 2

Given, one point =(2,−3)

Let, other point =(10,b)

absicca is x cordinate

(10−2) 2+(b+3) 2=108 2+(b 2+9+6b)=10

Squaring both sides, we get

64+b

+9+6b=100

(b+3)

=36

∴ b+3=6 and b+3=−6

∴ b=3 and b=−9

Your answer would be A(-3,-3)

The easiest way to solve this problem would be to graph it. Graph each of the points them count the units or squares between each point. Whichever one is only 8 units is the answer. Hope the image helps.

Joseph has invited a group of friends over to watch a football game and is getting a party platter of spicy wings and sweet wings to serve. Joseph starts his order with 16 spicy wings. He plans to order more sweet wings than spicy wings.
Let n represent the number of sweet wings that Joseph might order. Which inequality models the story?

Answers

Answer:

Since Joseph plans to order more sweet wings than spicy wings, the inequality that models the story is:

n > 16

This means that the number of sweet wings (n) must be greater than 16.

Step-by-step explanation:

Answer: n > 16 im pretty sure

Step-by-step explanation: to graph just put the uncolored in dot on 16 and draw an arrow to the right

This means that the teacher graded 8 quizzes before school.

2) Add how many was graded after school

We know that the teacher also did 15 of how many quizzes were left over after school.

Previously he/she had done 8 so we have to subtract this by 48

48 - 8 = 40

15 more were done so we have to subtract this too...

40 - 15 = 25

25 are left!

Which layer of the earth is responsible for continental and oceanic plate movement?
(I know this is in the wrong category, I could not find the right one.)

A. crust

B. mantle

C. inner core

D. outer core

Answers

The answer is the earths crust

Answer: B. Mantle

Step-by-step explanation:

I just couldn't pass up answering this question. I think the earth is very interesting.

The Earth's mantle is a thick layer of hot, flowing rock that lies beneath the crust. Convection currents within the mantle are responsible for the movement of the Earth's tectonic plates, which make up the continents and the ocean floor. As the mantle convects, it drags the plates along with it, causing them to move and interact with each other at their boundaries. This movement is responsible for many geological phenomena, including earthquakes, volcanoes, and the formation of mountain ranges.

Answers

Answer:

No Solution

Step-by-step explanation:

Substituting y = -4x into the first equation, we get:

8x + 5(-4x) = 24(-4x)

Simplifying this equation, we get:

8x - 20x = -96x

Dividing both sides by -12x, we get:

-4/3 = -96

This equation has no solution, which means that the system of equations is inconsistent and does not have a unique solution.

Therefore, the system of equations cannot be solved to find the values of x and y.

Question
On a piece of paper, use a protractor to construct right triangle ABC with AB=3 in., m∠A=90°, and m∠B=45°.

What statement is true about the triangle?

A/1).AC=3 in.
B/2).BC=3 in.
C/3).BC=6 in.
D/4).AC=6 in.

Answers

Answer:

AC=3 in.

Step-by-step explanation:

It is given in the figure attached, in Δ ABC

∠ A = 90°

m∠B = 45°

AB = 3 in.

We have to find all sides of the triangle given

we will apply sine in Δ ABC to find the measure of AC

sinB =

Now by cross multiplication

BC = 3√2 in.

Now by Pythagoras theorem

BC²= AC² + AB²

(3√2)² = AC² + 3²

18 - 9 = AC²

AC = √9 = 3

Now we come to the options you have mentioned

AC = 3 in. is the correct answer.
