The number of rows of seats needed to seat the greatest possible number of participants in each row is 5
<h3>What is Highest Common Factor ?</h3>
The highest common factor is the highest number that divides the numbers given.
On the basis of given data
Total number of children = 26
Total number of adults = 39
The highest common factor of both the number is 13 ,
Therefore the highest possible number of people that can sit in one row so that the number is in constant in all the rows.
So 2 rows of children of 13 each and
3 rows of adult of 13 each
Which makes the total number of rows = 5
Therefore the number of rows of seats needed to seat the greatest possible number of participants in each row is 5

The question is incomplete. Here is the complete question:
Which inequality is true for x = 20?
A. x + 30 < 3x
B. x - 5 < 2x - 35
C. x divided by 4 < x - 12
D. 2x < x + 22
Answer:
Options A, B and D.
Step-by-step explanation:
Given:
The value of 'x' is 20.
In order to find which options are correct, we need to plug in 20 for 'x' in each of the given inequalities and check which of them hold true.
Option A:
Substitute 20 for 'x' in the above inequality. This gives,
The given inequality is true as 50 is less than 60.
Option B:
Substitute 20 for 'x' in the above inequality. This gives,
15 < 5
The given inequality is false as 5 is less than 15.
Option C:
Substitute 20 for 'x' in the above inequality. This gives,
5 < 8
The given inequality is true as 5 is less than 8.
Option D:
Substitute 20 for 'x' in the above inequality. This gives,
40 < 42
The given inequality is true as 40 is less than 42.
Therefore, the correct options are A, B and D.
Hello from MrBillDoesMath!
Answer:
x = 12
Discussion:
From the diagram, the two triangles appear to be similiar. Then
28/7 = (6x + 28) /25
as the ratio of corresponding parts of similar triangle are the same.
28/7 = (6x +28)/25 => simplify. 28/7 = 4
4 = (6x + 28)/25 => multiply both sides by 25
4*25 = 6x + 28 => simplify, 4 * 25 = 100
100 = 6x + 28 => subtract 28 from both sides
100 -28 = 6x => simplify. 100 - 28 - 72
72 = 6x => divide both sides by 6
72/6 = 12 = x
Thank you,

2/3 x 5/6 = 5/9
3/2 x 6/5 = 9/5
It’s basically the numerator and denominator flipped
Answer: 2x^2 + 7x + 6
Step-by-step explanation:
You just add it up,
Because they aren’t the same power, you can’t add the x’s together.
Therefore they stay individual.
2x² + 7x + 6
