3Y-4X=6 MULTIPLY BY 3 & ADD.

12X+20Y=272

-12X+9Y=18

1. Find the distance from point P to QS

12345 [234]

Answer:

5.7 units

Step-by-step explanation:

The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).

Use distance formula to calculate distance between P and R:

$PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$P (1, 1) = (x_1, y_1)$

$R(-3, 5) = (x_2, y_2)$

Plug in the values into the formula.

$PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2}$

$PR = \sqrt{(-4)^2 + (4)^2}$

$PR = \sqrt{16 + 16}$

$PR = \sqrt{32}$

$PR = 5.7 units$ (to nearest tenth)

Scrat [10]

Answer:

14x - 6

Step-by-step explanation:

P = 2(length + width)

P = 2(6x - 2 + x - 1) = 2(7x - 3) = 14x - 6

For a Chinese New Year celebration, James and Zhou are making a dragon costume similar to the one shown above.

Lilit [14]

Answer:

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

<em>Let the length of fabric in meters still required be</em> = $x$

<em>The total length can be given as :</em>

⇒ $(15+17.6+x)\ m$

⇒ $(32.6+x)\ m$

The total fabric required = 56.6 m

So, the equation to find $x$ will be:

$32.6+x=56.6$

Subtracting both sides by 32.6

$32.6+x-32.6=56.6-32.6$

∴ $x=24$

Thus,<u> 24 meters</u> of fabric is still required to make the costume.
