Answer:
23
Step-by-step explanation:
Let the mean also is x
Mean = Sum of all observations / Total no of observations
x = 30 + 12 + 40 + 10 + x / 5
5x = 92 + x
4x = 92
x = 23
Therefore 23 is the mean and also one of the numbers.
The value of x such that mean of 30, x, 12, 40, and 10 is equal to x will be 23.
What is mean?The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.
Mean = sum of data / Number of data
It is known that,
Mean = sum of data / Number of data
x = (30 + x + 12 + 40 + 10)/5
5x = x + 92
4x = 92
x = 23
Hence "The value of x such that mean of 30, x, 12, 40, and 10 is equal to x will be 23".

The common difference between successive terms in this arithmetic sequence is 6.
Option D is the correct answer.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
We have,
The common difference between successive terms in the sequence 2, 8, 14, 20, 26, ... is 6.
To see why, notice that each term in the sequence is obtained by adding 6 to the previous term.
For example, to get from 2 to 8, we add 6. To get from 8 to 14, we add another 6.
This pattern continues for each successive term in the sequence.
Thus,
The common difference between successive terms in this arithmetic sequence is 6.

Step-by-step explanation:
Set notation is straightforward and just includes putting the lesser and greater signs. For the interval notation, square brackets are for less than and equal or greater than or equal, so I put one for -25. Parentheses are the opposite, only for strict greater or lesser than, so I put a parenthesis.

Answer:
B
Step-by-step explanation:
So we have the equation:
[tex]4xz-4yz=5[/tex]
And we want to find the value of 5/4x in terms of x and y.
From our original equation, let's factor out a 4z from the left. So:
[tex]4z(x-y)=5[/tex]
Now, divide both sides by 4z:
[tex]x-y=\frac{5}{4z}[/tex]
Therefore, the expression that represents 5/4z is x-y.

Samantha claims 3/5 is an integer is she correct?
Answer:
no
Step-by-step explanation:
because integers are positive and negative numbers
Answer:
She is not correct
Step-by-step explanation:
This is the answer because:
1) We know that an integer is either a negative or positive number which has no fractional components/ no relation to fractions.
2) This means that an integer should not be expressed in the x/y form, also known as the fraction form.
3) Integers should always be a whole number that is negative or positive. An integer should never be a "part" of a number.
Therefore, 3/5 in not an integer

What is the place value of 6 in the number 6,029?
Answer:
six thousand
Step-by-step explanation
it lies in place of thousand and value is 6
6* 1000=6000
The place value is thousand.
What is place value?Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.
given number:
6,029
So, place values are as follows:
9- ones
2- tens
0- hundred
6 - thousand

What is the measure of the smallest angle in the figure? The figure is not drawn to scale.
Answer:
(4x-3)°=37
Step-by-step explanation:
solve for x
6x-7+90+4x-3=180
10x=180-80
10x= 100
x=10°
from the equations;
4x-3= 4(10)-3=37° and
6x-7= 6(10)-7=53
therefore the smallest angle =(4x-3) =37
can you help me estimate 102.3+4.7
Answer: 107
Step-by-step explanation:
102.3 can be rounded down to 102 (because the 3 at the end of the number is less than 5)
4.7 can be rounded up to 5 (because the 7 at the end of the number is greater than 5).
102.3 → estimate = 102
4.7 → estimate = 5
estimated sum = 107
Note that estimating the sum is NOT the same as simply adding the numbers and then rounding the sum.

Jordan's team gained 12 yards in the first play in the 2nd play they lost 8 yards witch expression could be used to describe the total yards gained by the team
Answer:
The expression is (x + 4) yards where x yards represent the initial amount of yards had by tre team
Step-by-step explanation:
In this question, we are told to write an expression which can be used to describe the total yard gained by the team.
Now, before we can write an expression showing the yard gained by the team, we need a variable that will represent the amount of yard they had initially.
Let us represent this by x yard.
By gaining 12 yards in the first play, total amount of yards now become x + 12 yards
Now in the second play, they lost 8 yards and this translates to (x + 12)-8 = (x + 4) yards
