3x+4y+6z=15 Solve for x.

aalyn [17]

Answer:

Step-by-step explanation:

<h3>Question:-</h3>

To solve for x

<h3>Equation:-</h3>

3x + 4y + 6z = 15

<h3>Solution:-</h3>

=> 3x + 4y + 6z = 15

[On subtracting both sides with 4y]

=> 3x + 4y + 6z - 4y = 15 - 4y

[On Simplification]

=> 3x + 6z = 15 - 4y

[On subtracting both sides with 6z]

=> 3x + 6z - 6z = 15 - 4y - 6z

[On Simplification]

=> 3x = 15 - 4y - 6z

[On dividing both sides with 3]

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

[On Simplification]

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$

ikadub [295]

The base of the prism is a 3:4:5 right triangle.
One of the legs is its base and the other is its height. (The longest side is the hypotenuse!)

The area of the triangular base is bh/2 = (9)(12) / 2. There are two of these.
There are also three rectangular sides on the prism.
Their dimensions are 9 by 20, 12 by 20, and 15 by 20.

You can do the arithmetic from here.
And the answer is 828cm ^2

23 + 17 + 26 + 5 + 33 + 11 = 115

115 / 6 = 19.16666666666667
