There must be 5 rows for each row of girl to have only girls

The given parameters are:

Girls = 25

Boys = 20

To calculate the number of rows where each row has only girls, then we first calculate the ratio of boys to girls:

Ratio = Boys : Girls

Boys : Girls = 20 : 25

Divide by 5

Boys : Girls = 4 : 5

Rewrite as:

Boys \to 4

Girls \to 5

This means that there are 4 boys on each row for the boy rows

And there are 5 girls on each row for the girl rows

The number of row is then calculated as:

Rows = \frac{Total\ Girls}{Girl\ Ratio}

Rows = \frac{25}{5}

Total = 5

Hence, there must be 5 rows for each row of girl to have only girls

Which of the following are solutions to | x - 1 |=5x + 2 ?
shutvik [7]

Use the definition of absolute value,

|x| = \begin{cases} x & \text{if } x \ge 0 \\ -x & \text{if } x < 0 \end{cases}

If x - 1 ≥ 0, then |x - 1| = x - 1, and so

|x - 1| = 5x + 2

x - 1 = 5x + 2

4x = -3

x = -3/4

Otherwise, if x - 1 < 0, then |x - 1| = -(x - 1), which means

|x - 1| = 5x + 2

-x + 1 = 5x + 2

6x = -1

x = -1/6
