Answer:

For this case we must represent the following expression algebraically:

"eight more than the product of a number and two"

Let "x" be the variable that represents the unknown number

We have to:

the product of a number and two is represented as: [tex]2x[/tex]

Then, the full expression will be:

[tex]2x + 8[/tex]

Thus, we use multiplication and addition.

ANswer:

Option C

Answer: multiplication and addition

Step-by-step explanation:

In mathematics we use addition(+) operation to show "sum", subtraction (-) to show "difference" , multiplication (×) operation to show "product" and divide (÷) to show "quotient".

Given mathematical statement : eight more than the product of a number and two

Here, we use addition(+) operation to show "more than" and multiplication (×) operation to show "product" .

Hence, the two operations are needed to write the expression that represents are : multiplication and addition

Answer:

X=18

Step-by-step explanation:

Multiply the 6 and the 15= 90

Then left with 5x so then divide 90 and 5= 18

Left with X= 18

The value of x in the given equation is x = 18.

Given is an equation 5x/6 = 15, we need to find the value of x,

To solve for x, you need to isolate x on one side of the equation.

Here's how you can do it step by step:

Start with the equation: 5/6 x = 15

To isolate x, you need to get rid of the fraction on the left side. Since the fraction has a denominator of 6, you can multiply both sides of the equation by 6 to eliminate it:

(6) × (5/6 x) = (6) × 15

The 6 on the left side cancels out the denominator 6, leaving:

5x = 90

Now, to find the value of x, you need to get x by itself on one side. Since 5x means 5 times x, you can undo this by dividing both sides by 5:

5x / 5 = 90 / 5

This simplifies to:

x = 18

So, the value of x is 18.

Answer:

x > 7/3

Step-by-step explanation:

5(3x - 2) > 3(4x - 1)

First, use the distributive property on both sides.

15x - 10 > 12x - 3

Subtract 12x from both sides.

15x - 12x - 10 > 12x - 12x - 3

3x - 10 > -3

Add 10 to both sides.

3x - 10 + 10 > - 3 + 10

3x > 7

Divide both sides by 3.

3x/3 > 7/3

x > 7/3

Jorge's statement is partially correct. 0.029 can be written as a fraction but it is 29/1000, not 29/100 since it has three decimal places.

Jorge's statement that 0.029 can be written as 29/1000 is indeed correct. When you convert a decimal to a fraction, we count the number of decimal places, which determines the denominator of the fraction. In the case of 0.029, it has three decimal places, therefore, the denominator would be 1000 (the first place represents tenths, the second represents hundredths and third represents thousandths). Hence 0.029 as a fraction is written as 29/1000, not 29/100.

Answer:

42

Step-by-step explanation:

if you divide 546 with 13 it will give you 42 mostly because 546 is the total of miles that he drove so if you dive by how many days he has been driving you will get your answer.

Troy drove 546 miles over 13 days, resulting in an average of 42 miles driven each day after dividing the total miles by the number of days.

To find out how many miles Troy drove each day, we need to divide the total number of miles driven by the number of days. Troy drove a total of 546 miles over the course of 13 days.

Divide the total miles (546) by the number of days (13).

The calculation is:

546 miles / 13 days = 42 miles per day.

Therefore, Troy drove 42 miles each day.

The problem involves calculating a binomial probability for 12 out of 20 adults being satisfied with airlines, given a satisfaction rate of 66%. This uses the formula for Binomial Probability: P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k)).

The question involves using Binomial Probability in statistics. Here, the experiment is repeated 20 times (20 adults are selected), each trial is independent (one adult's answer doesn't affect another's), there are two possible outcomes (satisfied or unsatisfied), and the probability of success (being satisfied) is constant (66%).

To calculate the probability of exactly 12 adults being satisfied, we use the formula for Binomial Probability:

P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k))

By subbing in these values, we can calculate the desired outcome.

The first one. 55.3 and 40. 38

Step-by-step explanation:

Subtract all of the second legs from the first legs that they go with and find the biggest number. When this is done, the first one has the biggest number.

Answer:

The biggest decrease in time is 14.92 seconds.

Step-by-step explanation:

Consider the provided table.

Consider the row 1.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.3 seconds - 40.38 seconds = 14.92 seconds

Hence, the decrease in time is 14.92 seconds

Consider the row 2.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.29 seconds - 40.402 seconds = 14.888 seconds

Hence, the decrease in time is 14.888 seconds

Consider the row 3.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.295 seconds - 40.4 seconds = 14.895 seconds

Hence, the decrease in time is 14.895 seconds

Consider the row 4.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.037 seconds - 41.2 seconds = 13.837 seconds

Hence, the decrease in time is 13.837 seconds

From the above calculation it is clear that the biggest decrease in time is 14.92 seconds.

To determine the football team's change in field position using a number line, one would sequentially move 5 units left for each loss of 5 yards over 3 plays, resulting in a total change of -15 yards.

To find the football team's change in field position after the 3 plays, you can use a number line to represent the yards on the field.

If we consider the team's starting point as zero on the number line, each loss of 5 yards will be represented as moving 5 units to the left (into the negative side) from that starting point. Here's how you would calculate it step by step:

Mark the starting point at zero on the number line.

Since the team lost 5 yards on the first play, move 5 units to the left and mark that new point, which represents -5 yards.

Repeat the process for the second play, moving another 5 units to the left from the -5 mark to reach -10 yards.

Finally, for the third play, move yet another 5 units to the left to end up at -15 yards.

Therefore, after 3 plays with each losing 5 yards, the team's field position has changed by -15 yards.

Answer:

20 - 2n

Step-by-step explanation:

The sequence is arithmetic since the difference between consecutive terms is constant, that is

d = 16 - 18 = 14 - 16 = 12 - 14 = - 2

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 18 and d = - 2, thus

[tex]a_{n}[/tex] = 18 - 2(n - 1) = 18 - 2n + 2 = 20 - 2n

[tex]a_{n}[/tex] = 20 - 2n

If we know that [tex]x_{1} = 18[/tex] and [tex]r = -2[/tex], then the n-th term of the number sequence is [tex]f(n) = 18 -2\cdot (n-1)[/tex].

This sequence is an example of an arithmetic sequence, since each consecutive pair of elements has one and only one difference, that is to say:

[tex]r = x_{i+1}-x_{i}[/tex], [tex]\forall\,i\in \mathbb{N}[/tex] (1)

The expression for any arithmetic sequence is described by the following formula:

[tex]f(n) = x_{1} + r\cdot (n-1)[/tex], [tex]n \ge 1[/tex] (2)

Where:

If we know that [tex]x_{1} = 18[/tex] and [tex]r = -2[/tex], then the n-th term of the number sequence is [tex]f(n) = 18 -2\cdot (n-1)[/tex].
