Answer 1
i think i’m may be ‘B’ i’m so sorry if i’m incorrect!!
Answer 2

Answer:

B. 8n²−16n=−68

Step-by-step explanation:

First - Distribute the n & 10

n * 8n & n * -6 = 8n² - 6n

10 * -n & 10 * 7  = -10n +70

Second -  Move the 2 by subtracting

8n² - 6n - 10n +70 = 2 -> 8n² - 6n - 10n +70 - 2 = 2 - 2

Third - Combine like terms

-6n - 10n = -16n

70 - 2 = 68

8n² - 16n + 68 = 0

Fourth - Move 68 by subtracting

8n² - 16n + 68 - 68 = 0 - 68

8n² - 16n = -68

Answer:

That sucks do u know why

Step-by-step explanation:

A company has 24 employees. Each employee volunteers to bring 1 item to the local school
fundraiser

* One-eighth of the employees bring pencils

* One-third of the employees bring paper

* The number of employees who bring notebooks is double the number of employees who will
bring pencils.

* The rest of the employees bring backpacks.

How many employees bring backpacks?

Answers

Answer:

Step-by-step explanation:

1/8 into 24/8 would be 3

1/3 into 24/3 would be 8

double the amount of pencils would be 6

6+8+3=17

24-17=7

So, 7 employees bring backpacks.

The required number of employees to bring the backpack is 7.

Given that,
A company has 24 employees. Each employee volunteers to bring 1 item to the local school fundraiser.
One-eighth of the employees bring pencils, and One-third of the employees bring paper,  The number of employees who bring notebooks is double the number of employees who will bring pencils, the rest of the employees bring backpacks.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Total number of employees = 24
Number of employees bring pencil = 1/8 * 24 = 3
Number of employees bring paper = 1/ 3 * 24 = 8
Number of employees bring notebook = 2 * 3 = 6
Number of employees brings backpack = 24 - 6 - 8 - 3
                                                                   = 7

Thus, the required number of employees to bring the backpack is 7.

I WILL GIVE BRAINLIEST! DO NOT ANWSER IF YOU DON'T KNOW! Guy and Jim work at a furniture store . Guy is paid $185 per week plus 3% of his total sales, in dollars, x, which can be represented by g(x) = 185 + 0.03x. Jim is paid $275 per week plus 2.5 % of his totals sales in dollars, x, which can be represented by j(x) = 275 + 0.025 x . Determine the value of x, in dollars, that will make their weekly pay the same.

Answers

Answer:

X = 18 000

Step-by-step explanation:

185 + 0.03x = 275 + 0.025x

Subtract 0.025x from both sides

185 + 0.005x = 275

Subtract 185 from both sides

0.005x/0.005 = 90/0.005

X = 18 000

Verify by replacing x with 18 000

185 + 0.03(18000) = 275 + 0.025(18000)

185 + 540 = 275 + 450

725 = 725

Using the function g(x) = 0.4x - 1.8, what would the input need to be for an output of 4.6?

Answers

g(x) = 0.4x - 1.8

Since the output, or g(x), is 4.6, substitute that number in for g(x).

4.6 = 0.4x - 1.8

Add 1.8 to both sides of the equation.

4.6 + 1.8 = 0.4x - 1.8 + 1.8

6.4 = 0.4x

Now, divide 6.4 by 0.4.

The answer is x = 16. The output is also x.

The solution is, the value of x = 16.

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

g(x) = 0.4x - 1.8

Since the output, or g(x), is 4.6,

substitute that number in for g(x).

4.6 = 0.4x - 1.8

Add 1.8 to both sides of the equation.

4.6 + 1.8 = 0.4x - 1.8 + 1.8

6.4 = 0.4x

Now, divide 6.4 by 0.4.

The answer is x = 16.

The output is also x.

Hence, The solution is, the value of x = 16.

1. Find the median of the following data :
1) 3,1,5,6,3,4,5
2) 3,1,5,6,3,4,5,6

Answers

Answer:

a ) The first step -  arrange them in ascending or descending.

1,3,3,4,5,5,6

then median is to find the middle so -

the middle of this is "4" (there are odd numbers of numbers)

b) the first step- -  arrange them in ascending or descending.

1,3,3,4,4,4,6,6

then median is to find the middle so -

here the middle is 4 and 4 ( there are even numbers of numbers)

so you find average -

4+4/2 = 4

these are the answers I guess.

you have to put all the numbers from least to greatest then scratch off one from each side and do that until you get 1 number left wich should be 4
