To solve for q, we need to get q on one side and then simplify if needed.
Our current equation is:
2q + 18 = -5q -3
Let's get q by itself.
Add 5q to both sides.
7q + 18 = -3
Subtract 18 from both sides.
7q = -21
Divide both sides by 7.
q = -3
Your correct answer is B.)

Answer:
Step-by-step explanation:
Hello!
The variable of interest is:
X: height of seaweed.
X~N(μ;σ²)
μ= 10 cm
σ= 2 cm
You have to find the value of the variable X that separates the bottom 0.30 of the distribution from the top 0.70
P(X≤x)= 0.30
P(X≥x)= 0.70
Using the standard normal distribution you have to find the value of Z that separates the bottom 0.30 from the top 0.70 and then using the formula Z= (X-μ)/σ translate the Z value to the corresponding X value.
P(Z≤z)= 0.30
In the body of the table look for the probability of 0.30 and reach the margins to form the Z value. The mean of the distribution is "0" so below 50% of the distribution you'll find negative values.
z= -0.52
Now you have to clear the value of X:
Z= (X-μ)/σ
Z*σ= X-μ
X= (Z*σ)+μ
X= (-0.52*2)+10= 8.96
The value of seaweed height that divides the bottom 30% from the top 70% is 8.96 cm

Option 1 is better. 12% of $300 is $36, so even in just the first year, it grows by $6 more than if they picked the other option. I hope this helps :)
Answer:
6 paintings
Step-by-step explanation:
so it would be 1,290/215 = 6
I found the value for number 2 and it took some time to like calculate but here it is
$15,250
1.)$14,106.25
2.)$13,048.2812
3.)$12,069.6601
4.)$11,164.4356
5.)$10,327.1029
6.)$9,552.57018
7.)$8,836.12742
8.)$8,173.42
The numbers are the years but the value of the car would be number 8
