Step-by-step explanation:
Create an equation modeling the scenario. Use the equation to solve for the missing number. In your final answer, include the equation and all necessary calculations. Twice the sum of a number and seven is three times the number.
Answer:
2(n+7)=3n
Step-by-step explanation:
"A number" is unknown so just create a variable in this case I made it "n."
We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.

The Westward Movement was one of the greatest human migrations in history. It was a giant movement of people from all over the earth into nearly 2 million square miles newly acquired by the United States. Trappers came for fur, hunters for buffalo, settlers for rich farms, miners for gold and silver, cowboys for cattle, and carpenters, smiths, shop keepers and railroad workers to support all the rest. Everyone wanted land they could own themselves.
How did the Westward Movement have such a huge impact on the U.S.?
Group of answer choices
A) the new land the U.S. got had plenty of opportunities for many people
B) the Westward Movement was when people migrated
C) the land was easy to travel, especially in the beginning
D) the U.S. had closed immigration to foreign people
Answer:
In the mid-19th century, the quest for control of the West led to the annexation of Texas and the Mexican–American War. ... This expansion led to debates about the fate of slavery in the West, increasing tensions between the North and South that ultimately led to the collapse of American democracy and a brutal civil war.

Maria has a new fish tank for her goldfish. The tank measures 912 inches long, 312 inches wide, and 612 inches tall.
Part A:
What formula should Maria use if she wants to know the volume of her new fish tank?
Part B:
Using the formula you wrote for Part A, what is the volume of Maria's new fish tank?
I'm giving out Brainliest!
Step-by-step explanation:
step 1. V = LWH. L = length. W = width. H = height.
step 2. V = (912)(312)(612) = 174,140,928 in^3.
The volume of Maria's new fish tank is 174,140,928 cubic inch.
It is required to find the volume of Maria's new fish tank.
What is cuboid?In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.
Given :
Maria has a new fish tank for her goldfish.
The fish tank is in the shape of cuboid.
length=912 inches
width=312 inches
Height=612 inches
Part A
The formula of volume of her new fish tank
Volume=length ×width × height.
Part B
Volume=length ×width × height.
By the use of formula we have,
V = (912) ×(312) ×(612)
V= 174,140,928 cubic inch.
Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

You call your teacher and find out that the second part of the note should have said “sell four hot dogs and two bags of chips for $10.” What does that do for your system of equations now? With this new information, how much should each item cost? Again, show all of your work.
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips

the expressions a[8x+7] and 4x+3.5 are equivalent. what is the value of a
Answer:
[tex]a=0.5[/tex]
Step-by-step explanation:
Divide each term by [tex]8x+ 7[/tex] and simplify.
Hope this helps :)
-ilovejiminssi♡
a(8x + 7) = 4x + 3.5
8ax + 7a = 4x + 3.5
equating coefficients of x : 8a = 4 so a = 1/2
also 7a = 3.5 so a = 1/2
The value of a is 1/2
Two linear functions are represented in different formats.
Function 1:

0 −2
2 0
3 1

Function 2:
Graph of a line passing through the point begin ordered pair negative 2 comma 0 end ordered pair and the point begin ordered pair 0 comma 4 end ordered pair.
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
Step-by-step explanation:
Given that function 1 has the table;
x y
0 -2
2 0
3 1
5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.

The median and mean of the data is 7.5
What is Arithmetic Mean?The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.
Given:
According to box plot the mean is
= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26
= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26
= 195 / 26
= 7.5
Hence, the mean is 7.5.
Also, the median = (7+8)/2 = 7.5
