Answer:
8 red marbles.
Step-by-step explanation:
The ratio is 3:2, blue to red. If there's 12 blue marbles and the first part of the ratio's 3, then:
12/3=4
Then you take the 4 and multiply it by 2, the second half of the ration to get 8.
And so, the answer's 8. If you divide 12:8 by 4 each you get your original ratio of 3:2, so that's your way to check.

PLZ I HAVE TO FINISH THIS TEST TODAYYY
Answer:
4 tickets for $1
Step-by-step explanation:
I just divided 8 with 2.00 and got 4.
The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
At a school carnival, tickets can be purchased to participate in different activities.
The data are shown in the picture.
From the data:
y ∝ x
Removing the proportional sign:
y = kx
Plug x = 8
y = 2
2 = 8k
k = 1/4
Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

The profit y(in dollars) for a business from selling x coats is represented by y=47x . Graph the equation.
The graph of the equation is attached .
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope-intercept form of the line equation
y= mx + c
where m is the slope
b is the y-intercept
We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation
y=47x .
Now comparing with the slope-intercept form of the line equation;
m = 47
We know that the value of the y-intercept can be determined by setting x = 0
substitute x = 0 in the equation
y = 47(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The slope m = 47
The y-intercept b = 1
The graph of the equation is also attached.
