The equation is ![b=\frac{2A}{h}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B2A%7D%7Bh%7D)
Step-by-step explanation:
Let us revise how to make a variable subject of an equation
- Write the equation and circle the variable you want to make it subject
- Keep it in one side and move all other in the other side
- Make the coefficient of the subject 1
∵ A =
× b × h
∵ b is the subject
∴ Multiply the two sides by 2
∴ 2A = b × h
- Divide both sides by h
∴ ![\frac{2A}{h}= b](https://tex.z-dn.net/?f=%5Cfrac%7B2A%7D%7Bh%7D%3D%20b)
- Switch the two sides
∴ ![b=\frac{2A}{h}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B2A%7D%7Bh%7D)
The equation is ![b=\frac{2A}{h}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B2A%7D%7Bh%7D)

Answer:
Step-by-step explanation:
Answer:
A. 3 (1,2,3,4,5) B 60%
Step-by-step explanation:
Answer:
See the attached graphic
Step-by-step explanation:
1. Defense cards could be identify with <em>x</em> and offense cards with y.
2. Find the proportion:
<em>For every 4 defense cards (y), he owns 2 offense cards (x)</em>
<em>Offense cards (x) Defense cards (y)</em>
<em> 2 4</em>
<em> 3 6</em>
<em> 4 8</em>
If Chad has 4 offense cards, then he owns 8 Defense cards. Note that the proportional relationship between defense cards and offense cards is 2:1. In a mathematical expression:
![y=2x](https://tex.z-dn.net/?f=y%3D2x)
3. Graph: See the attached graphic. Where y-axis (vertical) represents the defense cards and x-axis (horisontal) represents the offense cards.
