Answer: =4.4n-13
Step-by-step explanation:
Let's simplify step-by-step.
2n−9−(−2.4n+4)
Distribute the Negative Sign:
=2n−9+−1(−2.4n+4)
=2n+−9+−1(−2.4n)+(−1)(4)
=2n+−9+2.4n+−4
Combine Like Terms:
=2n+−9+2.4n+−4
=(2n+2.4n)+(−9+−4)
=4.4n+−13

Step-by-step explanation:
you have to add the 3 numbers together to get 170
find the slope of the line
Answer:
[tex]m=2[/tex]
General Formulas and Concepts:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Step-by-step explanation:
Step 1: Define points
(-2, 2)
(0, 6)
Step 2: Find slope
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{6-2}{0-(-2)}[/tex]
[tex]m=\frac{4}{0+2}[/tex]
[tex]m=\frac{4}{2}[/tex]
[tex]m=2[/tex]
Twenty seven percent of the employees in a company have managerial positions, and 5 percent of the employees in the company have MBA degrees. Also, 59 percent of the managers have MBA degrees. Using the probability formulas, find the proportion of employees who either have MBAs or are managers.
Answer:
Step-by-step explanation:
Given that :
27% employees managerial position
5% Employee have MBA
59% of managers have MBA
Proportion of employees who either have MBA or are managers :
P(either manager or MBA) = P(Manager U MBA)
= P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
P(manager ) = 0.27
P(MBA) = 0.05
P(manager n MBA) * P(Manger) = 0.59 * 0.27 = 0.1593
P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
= 0.27 + 0.05 - 0.1593
= 0.1607

It takes Daphne 25 minutes to assemble a model plane. During her work day Daphne takes 30 minutes for lunch and one 15 minute break. Which inequality could Daphne use to determine the number of model planes
she can assemble in her 8 hour work day?
25p - 458
Answer:
y=25p-45Step-by-step explanation:
We first of all start by cumulating all the time she spent for break
lunch= 30min
break= 15min
total break= 45min
also the time taken to assemble one model plane 25min
let the number of hours be p
and the total number of model plane be y
The model is
y=25p-45
Answer: 25p +45 <480
Step-by-step explanation:
Determine if (-1,2) is a
solution to the system
(2x + 5y = 8
(3x - 2y = 5
Answer:
Not a solution.
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
[tex]\left \{ {{2x+5y=8} \atop {3x-2y=5}} \right.[/tex]
(-1, 2)
Step 2: Substitute and Check
Substitute: [tex]\left \{ {{2(-1)+5(2)=8} \atop {3(-1)-2(2)=5}} \right.[/tex]Multiply: [tex]\left \{ {{-2+10=8} \atop {-3-4=5}} \right.[/tex]Combine: [tex]\left \{ {{8=8} \atop {-7=5}} \right.[/tex]We see here that -7 ≠ 5. Therefore, (-1, 2) is not a solution of the systems of equations.
Manu gave the cashier $ 80 to pay for 5 pairs of doggy collars. The cashier gave him $20.50 in change. Each doggy collar cost the same amount. What is the cost in dollars and cents for each doggy collar?
Answer:
I think it is $11.90.
Step-by-step explanation:
All I did was this:
80 - 20.50 = 59.50.
59.50 / 5 = 11.90.
So if I'm wrong, shoot me :')
What is the difference between 20 and -9
20 is positive
-9 is negative
-9 is a smaller number
20 is a larger number
20 divided by 1 is 10
-9 divide by 1 is -9
There are infinite differences between then numbers...
Which of the following is the best description of a positive association between two variables?
A
The values will create a line when graphed on a scatterplot.
B
The values will create a line
with positive slope when graphed on a scatterplot.
с
As the value of one of the variables increases, the value of the other variable tends to decrease.
D
As the value of one of the variables increases, the value of the other variable tends to increase.
E
All values of both variables are positive.
The statement "if the value of one variable is increased so the value of the other variable is also increased" is correct.
The positive association between two variables refers to that if there is an increment in one variable so then the other variable should also increase.
And, if the one variable is decreasing, so the other variable is also decreasing. That means there is a direct relationship between these two variables.
So, the following statements do not consider the positive association:
The value does not develop a line in the case when it should be graphed on a scatterplot.The value does not develop a line in the case having a positive slope that is graphed on a scatterplot.There is no indirect relation between the two variables. The values of both variables can't be positive.Therefore we can conclude The statement "if the value of one variable is increased so the value of the other variable is also increased" is correct.

3(2x–7)=5–(1–x) plzz help ASAP
3(2x–7)=5–(1–x)
6x-21 = 5 - 1 + x
subtract x from both sides
5x - 21 = 5-1
combine like terms
5x - 21 = 4
add 21 to both sides
5x = 25
divide both sides by 5
x = 5

how many solutions does this equation have? -2(3h-1)=5(2h-3) have
the answer is a decimal
Step-by-step explanation:
-2(3h-1) = 5(2h-3)
clear brackets
-6h+2 = 10h-15
collect like terms
-6h-10h = -15-2
-16h = -17
divide the coefficient of h
h = -17 \ -16
h = 1.0625
One number is four more than a second number. Six times the first is 4 less than 4
Answer:
x = -23/6 4x = -46/3
Step-by-step explanation:
1st no. = 4x
2nd = x
as per the ques:
6 × 4x + 4 = 4
24x + 4 = 4
x = 4/24 - 4
= 1/6 - 4
x = -23/6
4x = 4 × -23/6
= -46/3
What percentage of students at your school prefers ice cream over cake?
Not really sure about what kind of an answer you want here...
I think you should count up every student's favorite choice and create a table. Then, let's just say there are a total of 30 students. 25 prefer ice cream over cake. The fraction of the students who prefer ice cream over cake is [tex]\frac{25}{30} = \frac{5}{6}[/tex].
Using a calculator, divide 5/6 to find the decimal percentage. 5/6 = 0.8333 (continuing on forever). Fractions are always more accurate, so when finding the percentage it won't be fully accurate since the 3s continue forever. This will be with a lot of numbers like 1/3 or even 2/3.
Now, shift the decimal two spaces forward, making 83.33
83.33% is your answer to this example problem I have created.
Do the same with yours!
Hope this helped! Feel free to ask anything else.
