1.2x10^4
Step-by-step explanation:
2.
negative exponent means it's a fraction so
4.5x10^-3 is 1/4500 or 0.0045 so
it's a very small number
1.
^4 means means move the decimal 4 spots
12×10^4 = 12,000
3.
^3 means move the decimal 3 spots
3.8 x 10^3 =
3800
4.
7.5x10^3 =
7500
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:
