Answer:
C
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
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

-Graphing Linear equalities with slope and y-intercept-
Answers
Answer:
I don't know how to type the table but the description is:
Slope= -3/2
y-intercept=0
y-intercept would be the b in y = mx + b and in this equation, it looks like there is no b but there is, it is just an invisible 0 because you don't need to add or subtract 0. The slope is -3/2 because m in the equation y=mx+b means slope.
hope that helps!

Stacie sends 12 text messages per hour each day from 4 p.m. to 8 p.m. Which of the following equations can be used to calculate the number of text messages that Stacie sends during these hours in x weeks? A. y = 48x B. y = 420x C. y = 84x D. y = 336x
Answers
Answer: D
Step-by-step explanation:
Stacie sends text messages for 4 hours each day (from 4 p.m. to 8 p.m.), so she sends a total of 12 x 4 = 48 text messages per day.
To calculate the number of text messages that Stacie sends during these hours in x weeks, we need to multiply the number of days by the number of text messages per day.
Since there are 7 days in a week, Stacie sends 48 x 7 = 336 text messages per week.
Therefore, the equation that can be used to calculate the number of text messages that Stacie sends during these hours in x weeks is:
y = 336x
So the answer is D.
Answer:
The answer would be D: y=366x
Step-by-step explanation:
The question asks for an equation that says how many messages she sends in x amount of weeks.
First, you would need to find how many messages she sends in 1 week. She sends 12 messages in a 4-hour span (4 pm to 8 pm) so that makes 48 messages in that span a day. Then you multiply that by 7 to see how many she sends in a week.
y represents the total number of messages, this is unknown. X represents the number of weeks.
Hope this helps :)

What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At point (-1, 3), an equation of this line can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 3 = (-1 - 3)/(1 + 1)(x + 1)
y - 3 = -2(x + 1)
y = -2x - 2 + 3
y = -2x + 1

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
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.

For this problem, we are asked to find equivalent expressions.
We should use the Distributive Property.
What is the Distributive Property?
The Distributive Property is a property that allows us to multiply the number outside of the parentheses into the numbers inside the parentheses. Think of the Distributive Property in the form of x (y + z); We multiply x with y and z.
Since we know what the Distributive Property is, we can begin finding equivalent expressions.
Let's start by distribution:
[tex]3x+3(x+y)\\3x + 3x + 3y\\6x + 3y[/tex]
A is a correct option.
Let's check B and C.
Distribute:
[tex]3(x+x+y)\\3x+3x+3y\\6x+3y[/tex]
B is a correct option.
Distributing isn't needed for expression C.
[tex]3xy\neq 6x + 3y[/tex]
C is an incorrect option.
A and B are the correct options.

Cloey has to go to England for a interview with the King. A plane ticket costs $4,000. She has $10,000. She is also buying lessons to speak English. The lessons cost $4,000. How much cash does she have left over?
Answers
Cloey will spend a total of $4,000 + $4,000 = $8,000 on the plane ticket and the English lessons.
To calculate how much cash she has left over, we need to subtract the total cost from her initial savings:
$10,000 - $8,000 = $2,000
Therefore, Cloey will have $2,000 cash left over after buying the plane ticket and English lessons.
