B + g = 16.....b = 16 - g
45b + 55g = 830
45(16 - g) + 55g = 830
720 - 45g + 55g = 830
-45g + 55g = 830 - 720
10g = 110
g = 110/10
g = 11 <=== there are 11 green cassettes
b + g = 16
b + 11 = 16
b = 16 - 11
b = 5 <=== there are 5 blue cassettes

Answer:
20%
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
- So, 20% were satisfied with their car
I hope this helps!
Answer:
<u>Domain = R - {3/2}</u>
Step-by-step explanation:
The domain of a rational function consists of all the real numbers x except those for which the denominator is 0
The given function is :

We need to find the zeros of the denominator
∴ 2x - 3 = 0 ⇒ add 3 to both sides
∴ 2x = 3 ⇒ divide both side by 2
∴ x = 3/2
The domain will be all real number except the zeros of the denominator.
So, Domain = R - {3/2}
Also, see the attached figure that represents the given function.
