Answer:
Let "C" represent the number of cookies Lacey made.
We can write the first sentence as: C - 8 = cookies remaining
We can write the second sentence as: (C - 8) / 3 = cookies for classmates
We can write the third sentence as: (C - 8) / 3 + 9 = cookies remaining
Therefore, the full equation is:
C - 8 / 3 + 9 = cookies remaining
Note that this equation is not solvable as written, since the operations are not in the correct order. To solve the equation, we must use the correct order of operations, which is:
1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Applying the order of operations, we get the following equation:
((C - 8) / 3) + 9 = cookies remaining
This equation is now solvable, and we can use algebra to solve for the variable "C".
To do this, we first need to isolate the variable on one side of the equation by moving all the other terms to the other side. We can do this by subtracting 9 from both sides of the equation, which gives us:
((C - 8) / 3) = cookies remaining - 9
Next, we need to get rid of the parentheses and the division by multiplying both sides of the equation by 3, which gives us:
C - 8 = 3 * (cookies remaining - 9)
Finally, we can solve for the variable "C" by adding 8 to both sides of the equation, which gives us:
C = 8 + 3 * (cookies remaining - 9)
This is the final equation, which shows the relationship between the number of cookies Lacey made and the number of cookies she had remaining after giving some to her friend and classmates.

Identify the numeric order of these fractions and mixed numbers from largest to smallest in the final form with common denominators 1 1/2, 1/4, 1 3/4, 5/6.
Answer:
1 3/4, 1 1/2, 5/6, 1/4
with a common denominator, it looks like this
21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4
The order of the fraction from largest number to smallest number is 1 3/4, 1 1/2, 5/6, and 1/4.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
1 1/2 = 3/2 = 1.5
1/4 = 0.25
1 3/4 = 7/4 = 1.75
5/6 = 0.83
So, the order from largest to smallest number is:
1 3/4, 1 1/2, 5/6, and 1/4.
Now, with a common denominator it will be:
21/12 = 1 3/4, 18/12 = 1 1/2 10/12 = 5/6 3/12 = 1/4

Two friends, Rahul and Arun, took summer jobs. The equation y = 17.3x represents Arun's earnings in dollars and cents, y, for working x hours. The graph below represents Rahul's earnings in dollars and cents, y, for working x hours.
How much more does Rahul earn per hour than Arun?
Answer: Rahul earns 3.5 dollars more per hour than Arun.
Step-by-step explanation:
17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.
Use the two points, (10,208) and (20, 416)
Use the formula for calculating slope:
416-208=208
20-10=10
---------------------
208/10= 20.8
Rahul's equation can be set up like this:
y=20.8x
Subtract:
20.8-17.3=3.5
Therefore, Rahul earns 3.50 dollars more per hour than Arun.

Answer: Volume of cube = 0.064 m s^3 = 0.064 s = cube √0.064 s = 0.4 m Therefore, length of all sides is 0.4
Answer: 0.4
Step-by-step explanation: To find the volume of a cube the formula for that axaxa = b and 0.064 = b (it is not axbxc because it is a CUBE). so that means you just have to find the cube root of 0.064 which is 0.4.

A new bakery is giving away free prizes for the grand opening. Every 5th customer will get a free bagel, every 9th customer will get a free blueberry muffin, and every 12th customer will get a free slice of carrot cake. Diego is the 23rd customer, he thinks he should get farther back in line to get a prize. Is he right? How far back should he go?
Answer:
1 spot back
Step-by-step explanation:
23 is closest to the number 24. 24 isn't divisible by 5 or 9 but it is by twelve. He Should only move 1 spot back because he is 1 in front of 24.
Answer: Diego is right and needs to go 1 place back.
Step-by-step explanation: We start by finding the least multiple for 5 it is 25, 9 is 27, and finally 12 is 24 and 24 is the closest so he only needs to back one place in line.

Answer:The value of the given expression is -6.93
How to simplify the expression?
The expression in the question is given as:
negative 15 plus the quantity negative 3 and seven tenths plus 9 and 15 hundredths end quantity divided by 5 all times 3 squared minus 4 and 7 tenths
Rewrite the expression properly
So, we have

Evaluate the quotient and the exponent
So, we have
-15 - 3.7 + 1.83 * 9 - 4.7
Evaluate the product
-15 - 3.7 + 16.47 - 4.7
Evaluate the sum and the difference
-6.93
Hence, the value of the given expression is -6.93 (none of the options is correct)

Answer:
-9 if that is to the power of 3 at the end
Step-by-step explanation:
Simplify the root.
What number multiplied by itself 3 times gives you 27?
3
18 - (3)^3 =
18 - 27 = -9
Also, a quicker way to do it when you get more confident is if you have a root (for example third root) and you raise it to the same exponent as is the root. (third root to third power) the root goes away and you are just left with the guts of that root.

8x/13 = 64/52
If answer is in a decimal, put in fraction (simplest form)
Answer: 2
Step-by-step explanation: This is incredibly simple first we can match the denominators, 4*13 = 52 and that means we have to do that to numerators to, 8x*4 = 32x so now our equation is 32x/52 = 64/52 and as we know 32*2 = 64 so that means x = 2.

Answer:
The answer is 3.
Step-by-step explanation:
So, 27 is equal to 3 times 3 times 3. How? 3 x 3 is 9, and 9 x 3 is 27. The question was asking you to find the number that when multipled by itself 3 times equals to 27. This is an easier question but if its a big number you can use a calculator.
Answer:
Check explanation
Step-by-step explanation:
With problems like these,
you need to find what number would be multiplied by 3 (the 'root index')
In this case, 3 can also be used,
3 x 3 x 3 = 27
It's a bit confusing but once you get the hang of it it becomes easier.
no other equations need to be done this is your answer:
[tex]\sqrt[3]{27}[/tex] = 3 x 3 x 3 = 27
_____
(in other problems there would be more steps,
the symbol is called a radical notion
The radicand is the number you are trying to reach (27 in this case)
the root index (3 in this case) is the number you use to find numbers that multiply *that* amount of times to equal the radicand.
3 can be multiplied 3 times to get 27
3 x 3 x 3 = 27
Hope this is clear!

1) Popcorn unit price: 17.57/7 = $2.51
2.51 x 3 = 7.53
Three bags of popcorn would cost $7.53.
2) Old games unit price: 73.10/5 = 14.62
14.62 x 6 = 87.72
If they sold six games they would've made $87.72.
3) Lollipop unit price: 20.51/7 = %2.93
2.39 x 4 = 11.72
Four lollipops would cost $11.72
4) Hotdogs unit price: 82.86/3 = $27.42
Hamburgers unit price: 55.12/2 $27.56
Hotdogs have the lower unit price. $27.42 < $27.56
5) Packs of paper unit price: 12.74/7 = $1.82
1.82 x 2 = 3.64
Two packs of paper would cost $3.64
6) Pair of shoes unit price: 49.32/4 = $12.33
12.33 x 6 = $73.98
Six pairs of shoes would cost $73.98
7) Brand A unit price: 71.28/6 = $11.88
Brand B unit price: 59.15/5 = $11.83
Brand B has the cheaper price. $11.83 < $11.88
8) Pounds of seeds unit price: 37.62/2 = $18.81
18.81 x 6 = $112.86
Six pounds of seeds would cost $112.86
9) Red Grapes unit price: .82
Green Grapes unit price: .84
Green grapes are more expensive. .84 > .82
10) Book Store unit price : 21.69/3 = $7.23
Online unit price: 14.28/2 = $7.14
Online has a lower unit price. $7.14 < $7.23
a school principal claims that grade 11 have a mean grade of 86 with a standard deviation of 4. suppose that the distribution is approximately normal, what is the possibility that a randomly selected grade will be less that 84?
Answer:
I'm not sure, but I think is this
z=(82–86)/4 = -1
z=(90–86)/4= 1
P(82<x<86) = 0.34134
P(86<x<90) = 0.34134
P(82<x<90) = 0.34134+0.34134 = 0.68268
