Answer:

The park is <u>31 inches</u> wide in the drawing.

Step-by-step explanation:

Given:

Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards.

The actual width of a neighborhood park is 62 yards.

Now, to find the width of park in drawing.

Let the width of park in drawing be $x.$

The scale drawing of the city is 1 inch : 2 yards.

So, 1 inch is equivalent to 2 yards.

Thus, $x$ is equivalent to 62 yards.

Now, to get the width of park in drawing by using cross multiplication method:

$\frac{1}{2} =\frac{x}{62}$

By cross multiplying we get:

$62=2x$

Dividing both sides by 2 we get:

$31=x$

$x=31\ inches.$

Therefore, the park is 31 inches wide in the drawing.

Rectangular classroom seats 72 students. If the seats were rearragned with 3 more seats rows in each row, the classroom would ha

Gre4nikov [31]

<span>Let the original number of seats in a row be x;
</span>Let the number rows be y;

( x + 3) * (y - 2 )= 72 and x * y = 72 => 72 + 3 * y - 2 * x = 72 => 3 * y = 2 * x;
=> x is divisible by 3;

1. x = 3 => y = 72 / 3 => y = 24;
2. x = 6 => y = 72 / 6 => y = 12;
3. x = 9 => y = 72 / 9 => y = 8;
4. x = 12 => y = 72 / 12 =. y = 6;
5. x = 24 =. y = 72 / 24 => y = 3;
6. x = 36 => y = 72 / 36 => y = 2;
7. x = 72 => y = 72 / 72 => y = 1;

My analysis tell me that the right answer is 9 seats in a row and 8 rows;
The original number in each row is 9.
