The simplified expression using the commutative property is in the first option :  1/3 + 2/3 + 3/5   = 1 + 3/5 = 1 3/5 .

now the given expression is 1/3 + 2/3 + 3/5 .

Therefore this expression can be simplified using the commutative property where we put the like terms together.

1/3 + 3/5  + 2/3

= 1/3 + 2/3 + 3/5 (here we use commutative property on the second and third terms of the expression)

= 1 + 3/5 (we know that 1/3 +2/3 = 1)

=1 3/5

Hence by using the commutative property we calculate the sum easily.

The commutative property applies to the arithmetic operations of addition and multiplication. This suggests that no matter how the numbers are arranged or placed, the result of adding or multiplying them remains the same.

As an illustration, 1 + 5 = 6 and 5 + 1 = 6. No matter how two numbers are added, the sum is unaffected. Multiplication uses the same principle. The commutative property does not hold for division and subtraction because the results are completely different when the numbers are rearranged.

The Linear function representing the total cost , where x is the number of tickets is  c(x) = 5. 50 + 20. 50x  , the correct option is (a) .

In the question ,

it is given that ,

the total cost for 5 tickets = $108

the service fees for the tickets to a basketball game = $5.50

we need to find the cost function for 5 tickets .

we substitute , the value of x = 5 in each option and check which option gives the cost as $108 .

Option (a)

c(x) = 5.50 + 20.50x

= 5.50 + 20.50(5)

= 108

Option(b)

c(x) = 5. 50x + 20. 50

= 5.50(5) + 20.50

= 48

Option(c)

c(x) = 5. 50 + 21. 60x

= 5.50 + 21.60(5)

= 113.5

Option(d)

c(x) = 5. 50x + 21. 60

= 5.50(5) + 21.60

= 49.1

So, from the answers above we can conclude that the cost function representing the cost for 5 tickets is c(x) = 5. 50 + 20. 50x   .

Therefore , The Linear function representing the total cost , where x is the number of tickets is  c(x) = 5.50 + 20.50x  .

Subtraction:

Subtraction serves as a representation for the act of removing items from a collection. The negative symbol stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above illustration) are then transported to a basket, the stack will now contain five oranges rather than nine. Therefore, the difference between 9 and 4 is 5, which equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter "-" represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.

The smallest possible value of the sum of the eight integers is given by:

116.

The eight integers in the problem are given as follows:

n, ..., n + 7.

Hence:

The smallest integer is more than 3/5 of the largest integer, hence the following inequality is built to relate them:

n > 3/5(n + 7)

Applying the distributive property on the right side, we have that:

n > 0.6n + 4.2.

0.4n > 4.2

n > 4.2/0.4

n > 10.5.

Hence the integers are:

11, 12, 13, 14, 15, 16, 17, 18.

(as 11 is the smallest integer possible).

Then the value of the sum is obtained as follows:

11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 116.

The sum of the infinite geometric sequence exists and is equal to 15.

We are given an expression for terms in a geometric progression. The term at position "n" is given by the following formula.

T(n) = 12(0.2)^(n - 1)

The general representation for the terms in a geometric sequence is given by : T(n) = a*r^(n - 1).

Here, the variables "a" and "r" represent the first term and the common ratio for the geometric progression. On comparing the given formula with the standard representation, we conclude that the first term of the given geometric progression is 12 and the common ratio is 0.2.

a = 12

r = 0.2

The sum of an infinite geometric sequence exists if the common ratio lies between -1 and 1.

-1 < r < 1

-1 < 0.2 < 1

The above inequality holds true, so the sum exists. Let the sum of the infinite geometric sequence be denoted by "S". The formula and calculations are below.

S = a/(1 - r)

S = 12(1 - 0.2)

S = 12/0.8

b The reason the function is linear is because the rate of change in the x and y-values are constant, such that the rate of change of the function is also constant

2. a. The function is not linear

b. This is so because the changes in the consecutive terms of the x-values is not constant while the change in the y-values is constant making the overall rate of change of the function (the slope of the function) to vary

3. a. The table is not a linear function

b. The reason why the table does not represent a linear function is because the change in the terms of the y-values is not constant

4. a. The table is a linear function

b. The reason why it is a linear function is because the changes in the x and y-values are constant

A linear function is a function that when plotted on a graph, forms a straight line.

1) The changes in x-values are;

Δx₁ = -2 - (-3) = 1

Δx₂ = -1 - (-2) = 1

Δx₃ = 0 - (-1) = 1

Δx₄ = 1 - 0 = 1

The changes in y-values are;

Δy₁ = 2 - 1 = 1

Δy₂ = 3 - 2 = 1

Δy₃ = 4 - 3 = 1

Δy₄ = 5 - 4 = 1

a. Is it a linear function? Yes

b. Why it is a linear function is because the first difference of the y-values and the change between consecutive x-values are both constant

2. The changes in x-values are;

Δx₁ = -2 - (-5) = 3

Δx₂ = -1 - (-2) = 1

Δx₃ = 2 - (-1) = 3

Δx₄ = 5 - 2 = 3

The changes in y-values are;

Δy₁ = 4 - 2 = 2

Δy₂ = 6 - 4 = 2

Δy₃ = 8 - 6 = 2

Δy₄ = 10 - 8 = 2

a. Is it a linear function? No

b. The reason why it is not a linear function is because the rate of change in the y-values is constant while the rate of change in the x-values varies, which indicates that the rate of the function also varies resulting in a non linear function.

3. The changes in x-values are;

Δx₁ = -5 - (-10) = 5

Δx₂ = 0 - (-5) = 5

Δx₃ = 5 - 0 = 5

Δx₄ = 10 - 5 = 5

The changes in y-values are;

Δy₁ = 4 - 9 = -5

Δy₂ = 2 - 4 = -2

Δy₃ = 0 - 2 = -2

Δy₄ = -3 - 0 = 2

a. Is it a linear function? No

b. The reason why the table of values does not represent the values of a linear function is that the first difference, which is the change in the consecutive y-values is not constant, such that the rate of changes of the ordered pairs of the function function is not constant and the graph therefore does not follow a straight line pattern

4) The changes in x-values are;

Δx₁ = 3 - (-1) = 4

Δx₂ = 7 - 3 = 4

Δx₃ = 11 - 7 = 4

Δx₄ = 15 - 11 = 4

The changes in y-values are;

Δy₁ = -4 - (-9) = 5

Δy₂ = 1 - (-4) = 5

Δy₃ = 6 - 1 = 5

Δy₄ = 11 - 6 = 5

The tons of waste recycled in 2021 was 619.4286 tons.

According to the question,

We have the following information:

In 2021: There were 2341 people living in the town. Each person in the town recycled an average of 264.6kg of waste. Aleks knows that 1 ton = 1000kg.

Now, the total waste recycled in 2021 can be found using multiplication:

Number of people*waste recycled by each person

2341*264.6

619428.6 kg

Now, we will convert this from kilogram to tons.

1 ton = 1000 kg

1 kg = 1/1000 ton

So, we will divide the waste in kilogram by 1000:

Total waste recycled = 619428.6/1000

Total waste recycled = 619.4286 tons

Hence, the tons of waste recycled in 2021 was 619.4286 tons.

Answer: 11 Cents per ounce of Juice

Step-by-step explanation:

The first step here is going to be to find how many ounces are in a gallon. This can be determined as shown using the given information you stated above:

1 gallon * 4 quarts * 2 pints * 2 cups * 8 ounces = 128 ounces in 1 gallon

Step 2 is multiplying 128 ounces by 2 because we have two gallons of juice in the bottle:

128 ounces per gallon* 2 gallons = 256 ounces

Step 3 is dividing the total cost of the juice, which is $28.16, by the number of total number ounces (256)

$28.16 / 256 ounces = .11 dollars per ounce (aka 11 cents per ounce)
