makkiz [27]

Answer:

$8x - 9 - 5x = 3x - 36 - 18x \\ 8x - 5x - 9 = 3x - 18x - 36 \\ 3x - 9 = - 15x - 36 \\ 3x = - 15x - 36 + 9 \\ 3x = - 15x - 27 \\ 3x + - 15x = - 27 \\ - 12x = - 27 \\ x = \frac{ 27}{12}$

seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who d

guajiro [1.7K]

So if x people were surveyed, $\frac{7}{8}$ people owned a bike and $\frac{1}{8}$ did not.

The difference between them is 72:
$\frac{7}{8}$ x-\frac{1}{8} [/tex] =72
so this means that
$\frac{6}{8}$ x=72

let's simplify:

$\frac{3}{4}$ x=72

and divide by 3:

$\frac{1}{4}$ x=24

and mupliply by 4:

x=96

so 96 people were surveyed
