After simplification of the given expression -5w /9 =30 , value of w is equal to -54.
As given in the question,
Given expression is equal to :
-5w / 9 = 30
Simplification of the given expression to get the value of w is :
-5w / 9 = 30
Multiply both the side of the given expression by 9 we get ,
-5w = 30 × 9
Divide both the side of the given expression by -5 we get,
-5w /-5 = ( 30 × 9 ) / -5
⇒ w = -(6 × 9 )
⇒ w = -54
Therefore, after simplification of the given expression -5w /9 =30 , value of w is equal to -54.

There are 40 fish in a pond. 12 of the fish are bream. Of the fish that are not bream, 1/4 are tench and the rest are carp.
What is the ratio of bream to tench to carp in the pond? Give your answer in its simplest form.
The ratio of bream to tench to carp is given by the expression; 12 : 7 : 21
What is a ratio of items?A ratio is a relationship between two or more items, that quantitatively expresses the number of times a unit item can be found within the quantity of each item in the set of items.
The given parameters are;
Number of fish in the pond = 40
The number of fish in the pond that are bream = 12
The number of fish that are tench = 1/4 of the fish that are not bream
The number of the fish that are carp = The rest of the fish that are not bream or carp
Required;
The ratio of bream to tench to carp of the fish in the pond.
Solution;
The number of fish that are either tench or carp = 40 - 12 = 28
The number of the fish that are tench = (1/4) × 28 = 7
Therefore;
The number of fish that are carp = 28 - 7 = 21
Which gives;
Number of bream in the pond = 12
Number of tench in the pond = 7
Number of carp in the pond = 21
The ratio of the number of bream to tench to carp in the pond is given by the expression;
[tex]\displaystyle{ \frac{12}{40}:\frac{7}{40}:\frac{21}{40}}[/tex]
Given that the expression for the ratio cannot be simplified further, we have;
The ratio of bream to tench to pond is 12 : 7 : 21

5. Find the equation of the line joining the points A(5, 7) and B(8, 12).
Given:
There are given that the two points:
[tex]A(5,7),and,B(8,12)[/tex]Explanation:
According to the question:
We need to find the equation of the line:
Then,
To find the equation of the line, first, we need to find the slope of the line.
So,
From the formula of the slope of the line:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where,
[tex]x_1=5,y_1=7,x_2=8,y_2=12[/tex]Then,
Put all the values into the given formula:
So,
[tex]\begin{gathered} m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ m=\frac{12-7}{8-5} \\ m=\frac{5}{3} \end{gathered}[/tex]Then,
From the formula of the equation of the line:
[tex]y-y_1=m(x-x_1)[/tex]Then,
Put the value of m into the above equation:
So,
[tex]\begin{gathered} y-y_{1}=m(x-x_{1}) \\ y-7=\frac{5}{3}(x-5) \\ 3y-21=5(x-5) \\ 3y-21=5x-25 \end{gathered}[/tex]Then,

Brickhouse is expected to pay a dividend of $3.30 and $2.52 over the next two years, respectively. after that, the company is expected to increase its annual dividend at 4.2 percent. what is the stock price today if the required return is 11.6 percent?
The company’s stock price today would be $33.46.
Dividend per share for the first 2 yearsDividend per share Year 1 (D1) = $3.30 per share
Dividend per share Year 2 (D2) = $2.52 per share
Calculation of Stock Price for the Year 2 (P2)Stock Price for the Year 2 (P2) = D2(1 + g) / (Ke – g)
= $2.52(1 + 0.042) / (0.1160 – 0.042)
= $2.63 / 0.0740
= $35.48 per share
The Stock Price todayThe company’s stock price is the Present Value of the future dividend payments and the present value the stock price for the year 2
The Stock Price = D1/(1 + r)1 + D2/(1 + r)2 + P2/(1 + r)2
= $3.30/(1 + 0.1160)1 + $2.52/(1 + 0.1160)2 + $35.48/(1 + 0.1160)2
= [$3.30 / 1.1160] + [$2.52 / 1.24546] + [$35.48 / 1.24546]

The values needed to complete the relative frequency table in the context of this problem are as follows:
a = 69.06%.b = 30.91%.c = 68.60%.d = 31.40%.What is a relative frequency?The relative frequency of an event in an experiment is calculated as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.
To find the relative frequency for boys, we look at the frequency two-way table, and consider that out of 110 boys, 76 went to 4-year colleges and 34 went to two year colleges, hence the relative frequencies are found as follows:
a = 76/110 = 0.6909 = 69.09%.b = 34/110 = 0.3091 = 30.91%.For girls, we also look at the frequency two-way table, and consider that out of 121 girls, 83 went to 4-year colleges and 38 went to two year colleges, hence the relative frequencies are found as follows:

or
y = 0.5x - 1

Step-by-step explanation:
To graph:
Start at (0, 0), or the origin, which is in the center of the coordinate plane.Move over x units to the right or left. Then, move over y units up or down. Mark the point.If you're working with a linear equation, draw lines connecting points from left to right. For a quadratic equation, connect points with curved lines.Another suggestion, is to use Desmos Graphing Calculator (website) and just plug in the points to see where to graph.

Answer: I hope these two answers help please mark me brainlist
Step-by-step explanation:
Simplifying
z = 6(x + -1h)
Reorder the terms:
z = 6(-1h + x)
z = (-1h * 6 + x * 6)
z = (-6h + 6x)
Solving
z = -6h + 6x
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Simplifying
z = -6h + 6x
or another answer
6(x-h)=z
Distribute 6 through the parentheses
6x-6h=z
Swap the sides of the equation
Z= 6x-6h
