40 × 25% = 10
40 - 10 = 30
The final price of the shoes is $30.
100 × 30% = 30

Answer:
the first one is d
Step-by-step explanation:
Answer:
1. D) D'(-4,0)
2. B) 11
Step-by-step explanation:
2. 5x+1+12x-8=180
17x-7=180
17x=187
x=11
Why are the solutions to the proportions StartFraction 40 over 8 EndFraction = StartFraction x over 10 EndFraction and StartFraction x over 40 EndFraction = StartFraction 10 over 8 EndFraction the same?
Answers
A because both result in the equation 8 x = 400, which simplifies to x = 5
B because both result in the equation 8 x = 400, which simplifies to x = 50
C because both result in the equation 40 x = 80, which simplifies to x = 2
D because both result in the equation 40 x = 80, which simplifies to x = 20

2. What is the average amount of money Claudio had in his account over the three weeks?
Answer:
he started off with $35.65 but i cant do the average
Step-by-step explanation:
to get what he started off with, do 28.75-12.40=16.35
then do 16.35-52=-35.65
you can remove the "-" from -35.65 to get what he had to begin with

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same. The correct option is B.
What is the associative property of addition?Suppose you've got 3 numbers a, b, and c.
Then, we have
(a+b) + c = a + (b + c)
This property is called associative property and it is called so because we can associate b with a, or b with c without altering the value of the addition.
What is the commutative property of addition?The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be the same.
For two numbers x and y, we have:
x + y = y + x
Thus, if we take 3 numbers as a,b and c, then:
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
And so on for any amount of numbers.
The best use of the associative and commutative properties to make simplifying -1/3-10+7+2/3+5 easier is [-1/3+(-10)]+[7+2/3+5].
Hence, the correct option is B.

Magdeline wants to know if the number of words on a page in her computer science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9
She claims that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page. Based on the data, is this a valid inference? (10 points)
Group of answer choices
Yes, because there is a lot of variability in the computer science book data
Yes, because the mean is larger in the computer science book
No, because the mean is larger in the computer science book
No, because there is a lot of variability in the computer science book data (brainliest if its right)
Answer:
The answer is D: To know on which book, number of words is more between, Computer Science and Math
Magdeline selects 25 pages from each book, then Calculates Mean, Median, Mean Absolute Deviation of number of words on each page.
Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9
Observing what Magdeline has Done,
Mean is Sum of words on each page of 25 pages divided by 25.
1. Mean of Computer Science book is more than mean number of words on pages of math book.
2.And, Median means , computer science book has more pages which contains 40 words ,and Math book has more pages which contain 45 words.
3.Now,Coming to Mean Absolute Deviation, which measures the Variability from Mean.
In computer science book ,there is more Variability that is, 9.4 and 1.9 in math book.
So, just by claiming, that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page appears invalid Inference, because variability from mean in computer science book is more than variability from mean in Math book because Mean Absolute Deviation measures Variability fro mean.

Which ordered pairs in the form (x, y) are solutions to the equation
7x−5y=28?
Select each correct answer.
A. (4, 10)
B. (−1, −7)
C. (7, 9)
D. (−6, −14)
When I tried to solve for 5y I got 5.6
Options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
7x - 5y = 28
From the above equation:
y = mx + c
On comparing:
y = (7/5)x - 28/5
m = 7/5
c = -28/5
After plotting the graph of the equation:
From the graph:
B. (−1, −7)
D. (−6, −14) are the ordered pairs in the form (x, y) that are solutions to the equation.
Thus, options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.

The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.
How many gallons of water will the dishwasher use to wash 12 loads of dishes?
Answer:
I believe it 96.
Step-by-step explanation:
32÷4=8
4×8=32
12×8=96
Answer:
96 gallons
Step-by-step explanation:
So to wash 4 loads of dishes, you need 32 gallons. If you divide 32 by 4 you get 8. That means you need 8 gallons of water per load. Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96. This means you need 96 gallons of water for 12 loads of dishes. Hope it helps!
