If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14     /*3
_________
6x – 3y = 3
<span>–6x + 18y = 42
</span>_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

<span>6x – 3y = 3
</span>6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

Radda [10]

First solve the return in each price per unit

Return = number units sold x price per unit

Return1 = 5000 units x Php 900

Return1 = php 4,500,000

Next is solve the other price per unit

Return2 = number units sold x price per unit

Return2 = (5000 + 1500 units0 x ( php 900 – 100)

Return2 = php 5,200,000

So the php 800 per unit will have greater return

Answer:

A. The length of the second leg is 8.5 inches

B. The length of the three-dimensional diagonal is 9.9 inches

Step-by-step explanation:

Let us revise the relation between the hypotenuse and the two legs of a right triangle

(hypotenuse)² = (vertical leg)² + (horizontal leg)²

∵ The length of the rectangular box = 8 inches

∵ The width of the rectangular box = 3 inches

∵ The height of the rectangular box = 5 inches

∵ Length and width are perpendicular to each other

∴ The Δ whose legs are 3 and 8 is a right triangle

In the right Δ whose legs are 3 and 8

∵ (hypotenuse)² = (3)² + (8)²

∴ (hypotenuse)² = 9 + 64

∴ (hypotenuse)² = 73

- Take √  for both sides

∴ hypotenuse = \sqrt{73} = 8.544003745

- Round it to the nearest tenth of one inch

∴ hypotenuse = 8.5 inches

A.

The 3-dimensional diagonal is the hypotenuse of a right triangle whose legs are the vertical edge and the hypotenuse of the right triangle whose legs are 3 and 8

∵ The hypotenuse of the right triangle whose legs are 3 and

   8 is 8.5 inches

∴ The length of the second leg is 8.5 inches

B.

In the right triangle whose hypotenuse is the 3-dimensional diagonal and legs are the vertical edge , the hypotenuse of the right triangle whose legs are 3 and 8

∵ (3-dimensional diagonal)² = (5)² + (73)²

∴ (3-dimensional diagonal)² = 25 + 73

∴ (3-dimensional diagonal)² = 98

- Take √ for both sides

∴ 3-dimensional diagonal = \sqrt{98} = 9.899494937

- Round it to the nearest tenth of an inch

∴ 3-dimensional diagonal = 9.9 inches

∴ The length of the three-dimensional diagonal is 9.9 inches

<em>V.I.N: you can find the length of the  three-dimensional diagonal by using this rule → </em>d=\sqrt{l^{2}+w^{2}+h^{2}}<em> </em>
