Which shows the best use of the associative and commutative properties to make simplifying -1/3-10+7+2/3+5 easier?
A. [5+(-1/3)+(-10)]+(2/3+7)
B. [-1/3+(-10)]+[7+2/3+5]
C. (-1/3+2/3)+[5+7+(-10)]
D. [-1/3+7+(-10)]+(5+2/3)
(I'll give brainliest for correct and accurate answer.)
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.

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.

A family drives 325 miles per day during a road trip.
Part A
Select the correct symbol to complete the inequality that represents how many days, d, the family must drive to travel at least 1,300 miles.
325d 1,300
00:00
Part B
For how many days must the family drive to travel at least 1,300 miles? Enter your answer in the box.
days
Answer:
Part A = the middle one
Part B = 4 days
Step-by-step explanation:
1,300 / 4 = 325
325 x 4 = 1,300
Inequality to represent number of days is 325d ≥ 1300.
Number of days to travel at least 1300 is 4.
What is inequality?An inequality is a mathematical expression in which both sides are not equal. Unlike equations, inequalities compare two values. Equal signs between are replaced by less than (or less than), greater than (or greater than), or not equals signs.
Given,
Family drives 325 miles per day
To travel at least 1300 miles
Let number of days be d
then
325d ≥ 1300
Dividing with 325 on both sides
d ≥ 1300/325
d ≥ 4
Hence, 325d ≥ 1300 is the inequality that represents number of days d to travel at least. 4 days is the least number of days.

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science 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
Art 68.7 50 15.4
Science 54.2 55 7.9
She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference? (10 points)
Group of answer choices
Yes, because the mean is larger in the art book
No, because the mean is larger in the art book
Yes, because there is a lot of variability in the art book data
No, because there is a lot of variability in the art book data

5x - 29.4 + 1/2x when x is 11/5
Answer:
-17.3
Step-by-step explanation:
Evaluate 5 x + x/2 - 29.4 where x = 11/5:
5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5
Hint: | Express 5×11/5 as a single fraction.
5×11/5 = (5×11)/5:
(5×11)/5 - 29.4 + (11/5)/2
Hint: | Express (11/5)/2 as a single fraction.
(11/5)/2 = 11/(2×5):
(5×11)/5 - 29.4 + 11/(2×5)
Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.
(5×11)/5 = 5/5×11 = 11:
11 - 29.4 + 11/(2×5)
Hint: | Multiply 2 and 5 together.
2×5 = 10:
11 - 29.4 + 11/10
Hint: | Approximate 11/10.
11/10≈1.1:
11 - 29.4 + 1.1

Wendy has 10 ½ pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 ¼ pounds. How many containers does she need? Show your work and answer in a complete sentence.
Answer:
9 containers
Step-by-step explanation:
Since Wendy wants to divide the 10 [tex]\frac{1}{2}[/tex] pounds of the potato salad into 1 [tex]\frac{1}{4}[/tex] pounds for each container, You just divide 10 [tex]\frac{1}{2}[/tex] by 1 [tex]\frac{1}{4}[/tex] using the following method:
Convert 10 [tex]\frac{1}{2}[/tex] into an improper fraction:
[tex]\frac{21}{2}[/tex]
Convert 1 [tex]\frac{1}{4}[/tex] into an improper fraction:
[tex]\frac{5}{4}[/tex]
Then finally divide [tex]\frac{21}{2}[/tex] by [tex]\frac{5}{4}[/tex] :
[tex]\frac{21}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]
This is the same as [tex]\frac{21}{2}[/tex] times the reciprocal of [tex]\frac{5}{4}[/tex]:
[tex]\frac{21}{2}[/tex] × [tex]\frac{4}{5}[/tex] = [tex]\frac{42}{5}[/tex] = 8.4
Since we cannot have 8.4 containers, we round it up to 9 containers, because for 8 containers, there will still be some pounds of potato salad left.
Which phrases can be represented by the expression 60w? Check all that apply. the product of sixty and a number sixty times a number the difference of a number and sixty the quotient of a number and sixty a number divided by sixty the sum of a number and sixty
Answer:
The product of 60 and a number and Sixty times a number.

Julie paid $43 for 8 shirts. At this rate, how much will she pay for 12 shirts?
Answer:
$64.56
Step-by-step explanation:
If she paid 43 dollars for 8 shirts, then that means she paid about 5.38 dollars each for one shirt. (43/8 = 5.375)
Because we are finding the price for 12 shirts, multiply the price of one shirt ($5.38) by the total number of shirts (12) we are buying so, 5.38*12 = $64.56
Our answer is $64.56. :D
Answer:
$64.50
Step-by-step explanation:
To find the unit rate: 43/8=5.375
To find how much for 12 shirts: 12 x 5.375 = 64.50.
