20x + 12 = 4(_+_)
Answer:
20x + 12 = 4(5x+3)
Step-by-step explanation:
4*5x = 20x and 4*3 = 12
The complete expression will be written as 20x + 12 = 4(5x+3).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,
4 x ( 5x) = 20x
4 x 3 = 12
20x + 12 = 4(5x+3).
Therefore, the complete expression will be written as 20x + 12 = 4(5x+3).

What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Karla who is creating a survey with 6 questions. She suspects that the order of the questions may influence the responses, so she wants to create multiple versions of the survey with the same 6 questions in different orders.
Assume that the she has to arrange the [x] questions. Then the number of unique ways are there to arrange the questions will be x². For [x] = 6, we can write the number of ways to be (6 x 6) = 36.
Therefore, the number of unique ways to arrange the questions will be 36.

if the least value of n is 5, which inequality best shows all the possible values of n?
n ≥ 5
n ≤ 5
n < 5
n > 5
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."

Answer:
1:5 4:20
Step-by-step explanation:
Because say you got 1 right out of 5 on test you get a 20%
since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.
In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.

When Rafiq left home on a business trip
he noted that the odometer on his car
read 47,823. He drove 3 h 15 min and
then noted that the odometer read
48,017. Find his average speed in miles
per hour.
He travelled : 48017 - 47823 = 194 (miles)
15 mins = 1/4 hours => 3h 15min = 3 1/4 hours = 13/4 hours
So, he travelled at an average speed of 194 : 13/4 = 59 (miles/h)

Estimate the size of a crowd standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street. Assume that each person occupies 2. 5 square feet.
The size of the crowd is 21,120 standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street.
How much 1 mile into feet?A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers.
Given
The size of a crowd standing along 1 mile section of parade route that is 10 feet deep on both sides of the street assume that each person occupies 2.5 square feet.
1 miles is equal to 5280 feet thus,
[tex]\rm= 5280 \times 10\\\\= 52800[/tex]
Divide this by the amount of space a person takes up
[tex]= \dfrac{52800 }{ 2.5}\\\\ = 21120[/tex]

What is an equation of the line that passes through the points (-8, 1) and(7,1)?
please help im giving 20 points to who ever answers it
Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation [tex]\frac{y_{1} - y_{2}}{x_{1}-x_{2}}[/tex] then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)

Which quadratic function in vertex form has a vertex at (-2, 6) and passes through the point (-4, 8)?
A. y = 1/2 ( x - 2 ) ^2 + 6
B. y = -1/2 ( x - 2 ) ^2 - 6
C. y = -1/2 ( x - 2 ) ^2 + 6
D. y = 1/2 ( x + 2 ) ^2 + 6
Answer:
y = -1/2(x + 4)² + 2 or y = -1/2x²- 4x - 6
Step-by-step explanation:
Given
Vertex = (-4, 2)
The graph passes through the point (-8, -6)
The function in vertex form is:
y = a(x + 4)² + 2
Substitute the coordinates of (-8, -6) and find the value of a:
-6 = a(-8 + 4)² + 2
-8 = 16a
a = -1/2
The function is:
y = -1/2(x + 4)² + 2
or in standard form:
y = -1/2(x² + 8x + 16) + 2 = -1/2x²- 4x - 6
