Answers
The store has sold 6,232 laptops since it opened.
Option B is the correct answer.
We have,
Step 1:
Identify the number of laptops sold last month.
The problem states that the store sold 82 laptops in the past month.
Step 2:
Determine the total number of times the store has sold laptops since it opened.
The problem says that the store has sold 76 times the number of laptops sold last month.
So, we need to multiply 82 by 76.
82 laptops * 76
= 6,232 laptops

Please SHOW ALL WORK, define your variables, and make a complete sentence for your answer.
Answers
Answer:
There are 9 lilies and 4 tulips.
Step-by-step explanation:
Step One: Create Let Statements
Let x= the number of lilies
Let 13-x= the number of tulips
Step Two: Create an Equation
14.85=1.25x+.90(13-x)
Distribute 14.85=1.25x+11.7-.90x
Combine like terms 14.85=11.7+0.35x
Subtract 11.7 from both sides 3.15=0.35x
Divide both sides by 0.359=x

The mean of the dataset is 3.55
How do determine the mean?
The dataset is given as:
0 | 3, 8
1 | 0, 1, 4, 7,
2 | 2, 4, 5
3 | 5 0
Remove the stems
3, 8
0, 1, 4, 7,
2, 4, 5
5 0
The mean is then calculated as:
Mean = Sum/Count
So, we have:
Mean = (3 + 8 + 0 + 1 + 4 + 7 + 2+ 4 + 5 + 5 + 0)/11
Evaluate
Mean = 3.55
Hence, the mean of the data is 3.55

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answers
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62
Answer:

The answer is 27.62

Please help me. X/6 ≥ 7. I also need to know how this would be graphed thank you.
Answers
Answer: The inequality solves to x ≥ 42
The graph is shown below
==================================================
Explanation:
We have some unknown number x, and we're dividing by 6 to form the fraction x/6. That result is 7 or larger which means we write x/6 ≥ 7
To solve for x, we undo the division. We'll multiply both sides by 6. That's how we get to x ≥ 42
The graph will involve a number line. Plot a closed filled in circle at 42 on the number line. Shade to the right. This visually represents any number that is 42 or larger. The endpoint 42 itself is included in the solution set.
Side note: We would use an open circle if we didn't have the "or equal to" portion for the inequality sign.

After reading 234 pages of a book Henry still had 1/3 left of the book. How mnay pages are their in the whole book?
PLSS HURRY!!
Answers
Answer:
702 pages
Step-by-step explanation:
1/3= 234
234*3=702
Answer:
351 pages
Step-by-step explanation:
If Henry still has 1/3 left that means that 234 was 2/3 of the book because 1/3 + 2/3 = 3/3 = The whole book.
To find out how many pages 1/3 is, we have to divide 234 by 2 because 234 is 2 thirds added together or 1 third multiplied by 2 and the inverse of that is divided by 2.
234 ÷ 2 = 117
So 1/3 is equal to 117 pages.
Like I said before 1/3 + 2/3 = 3/3 = The whole book.
117 is equal to 1/3 and 234 is equal to 2/3 so we add them together.
117 + 234 = 351
I hope that made sense.
