Khan academy algebra video why we do the same thing to both sides of an equation

1 answer:

4 0

I haven't seen this video but the way I think of it is to compare the equation with a chemical balance. Both sides have equal weights and the pointer is at zero. To maintain the pointer at zero if we add/take away a weight from one side we have to do the same thing on the other side.

Answer:

To find the slope, use the slope formula. The slope formula is Y2-Y1/X2-X1. Plug in any two points into the equation and solve. I will use (6,4) and (9,6).

6-4/9-6

2/3

The slope of the proportional relationship is 2/3.

Hope this helps! :)

Given

A candy bar box is in the shape of a triangular prism.

The volume of the box is 1,200 cubic centimeters.

A triangular prism is shown with a base of the triangle labeled 10 cm, sides of the triangles labeled 13 cm, and length of the box equal to 20 cm.

<h3>The volume of the prism;</h3>

The volume of a triangular prism is given by the formula;

$\rm Volume=\dfrac{1}{2} \times length \times width \times height$

Part A: What is the height of the base?

The height of the base is given by;

$\rm Volume=\dfrac{1}{2} \times length \times width \times height\\\\1200=\dfrac{1}{2}\times 20 \times 10 \times Height\\\\Height =\dfrac{1200\times 2}{20 \times 10}\\\\Height =\dfrac{2400}{200}\\\\Height = 12 \ cm$

The height of the base is 12cm.

Part B: What is the approximate amount of cardboard used to make the candy box?

The approximate amount of cardboard used to make the candy box is given by;

$\rm Area = 2 \times length \times width+ length \times width \\\\Area = 2\times 20 \times 10+ 20\times 10\\\\Area = 520+200 \\\\Area = 720$

The approximate amount of cardboard used to make the candy box is 720 cm².
