Answer:

x = 7

Step-by-step explanation:

3x+5 = 5x-9

(Subtract 3x from both sides)

5 = 2x-9

(Add 9 to both sides)

14 = 2x

(Divide 2x from both sides)

7 = X

The equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

<h3>Write an equation that models the movement of Tanus around Ini, where Ini is located at (0, 0)</h3>

The given parameters are:

The length of Tanus’ major axis = 150 million miles

The length of its minor axis = 75 million miles

The center of the ellipse = (0, 0) --- the location of Ini

When the coordinate of the center of an ellipse is (0, 0), the standard form of the ellipse is represented as:

x^2/a^2 + y^2/b^2 = 1

Where:

Length of the major axis = 2a

Length of the minor axis = 2b

This means that:

2a = 150 and 2b = 75

Divide both sides of 2a = 150 by 2

a = 75

Divide both sides of 2b = 75 by 2

b = 37.5

Substitute b = 37.5 and a = 75 in the standard form of the ellipse represented as: x^2/a^2 + y^2/b^2 = 1

x^2/75^2 + y^2/37.5^2 = 1

Hence, the equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

The length of a rectangle is 8 times it's width. The perimeter is 126 cm. What is the length of the rectangle?
agasfer [191]

Answer:

width: 7 cm

length: 56 cm

Step-by-step explanation:

Let:

x=width

8x=length

P=2l+2w

126=2x + 2(8x)

126=2x+16x

18x=126

x=7

width: 7 cm

length: 56 cm

hope this helps!!
