Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

0.4(12 - 3x) = 0.3(12x - 16)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute:                                4.8 - 1.2x = 3.6x - 4.8
  2. Add 1.2x on both sides:          4.8 = 4.8x - 4.8
  3. Add 4.8 on both sides:           9.6 = 4.8x
  4. Divide 4.8 on both sides:       2 = x
  5. Rewrite:                                   x = 2

Huey has a fish tank that measures 5 feet long by 2 feet wide and 2 feet tall . The volume of the tank.
iris [78.8K]
This is a simple problem

First, take common sense and apply it here. The problem doesn't specifically tell you what the shape ACTUALLY is, but we can also apply what we know about geometry here, as well as what we know in general. Fish tanks most commonly come in 2 shapes: Square's and Rectangles. Fish tanks are what we call "3D" objects (meaning it's just not flat like a piece of paper", and the shapes are known as "Cubes and Rectangular Prisms".

Well, we know that squares/cubes have to have even sides. The problem states the tank is 5(l) by 2(w) by 2(h). This means it CAN'T be a cube, thus meaning it's a rectangular prism.

Now, to calculate volume, we have to know the formula. For this, the formula for volume is as follows: V=lwh
This means Volume=Length*Width*Height

So, do replace the words with what you know you already have. Let's make a list:
Length=5
Width=2
Height=2

V=lwh-----V=5*2*2

Now, work it out. 5*2=10*2=20, Left to right

Your answer here is V=20

~Hope this helps!

Isabel joins a service to download movies. She pays $2 per movie, but she gets the first 5 movies for free. How many movies, m,
Damm [24]

The first question the answer to it is 30.

To do that divide 50/2 and see how many movies she can buy, which 25, then add the 5 free movies which gives you 30.

And the second part of the question I think is missing a picture or something.
