At the Wild West amusement park, Florence's favorite ride is the Blazing Bullet roller coaster. The roller coaster normally has a lot of seats to choose from, but Florence noticed that 12 of the seats are now reserved for season pass holders. There are 42 seats remaining for people without season passes. Let s represent the total number of seats on the Blazing Bullet roller coaster. Which equation models the problem?
Answers
Answer:
s=42+12
if there were 42 seats remaining and 12 seats reserved, adding both of them together would give you the total number of seats
Answer: s-12=42
Step-by-step explanation:
We don’t see any multiple choice problems but I think the answer would be this.

Answer: Jeremy will need 36 gallons of brown material and 12 gallons of green material.
explanation: I did the test and got the question right. hope this helps!
The correct choice is: Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Brown Material: 12.75, 18.6, 24, E (E is missing, represents the unknown value)
Green Material: 4.25, B (B is missing, represents the unknown value), D (D is missing, represents the unknown value), 11.5
Total: A (A is missing, represents the unknown value), C (C is missing, represents the unknown value), 32, 46
We know that Jeremy needs a total of 48 gallons of compost. So, we can set up an equation:
A + C = 48
From the brown material data, the total brown material is 12.75 + 18.6 + 24 + E:
12.75 + 18.6 + 24 + E = A
From the green material data, the total green material is 4.25 + B + D + 11.5:
4.25 + B + D + 11.5 = C
Now, let's look at the given total values:
A + C = 32 + 46 = 78
We can now set up a system of equations:
12.75 + 18.6 + 24 + E = A ........(1)
4.25 + B + D + 11.5 = C ........(2)
A + C = 78 ........(3)
Now, to find the values of A and C, let's use equation (3):
A + C = 78
From the choices provided, let's try option (A) Jeremy will need 36 gallons of brown material and 12 gallons of green material.
If Jeremy needs 36 gallons of brown material, then A would be 36. Let's see if this fits:
A + C = 78
36 + C = 78
C = 78 - 36
C = 42
Now, let's check if this aligns with the green material:
4.25 + B + D + 11.5 = C
4.25 + B + D + 11.5 = 42
Now, B and D must be positive values, and they need to sum up to 42 - (4.25 + 11.5) = 26.25.
There are various combinations for B and D that satisfy this, such as B = 20 and D = 6.25, or B = 15 and D = 11.25.
But since none of the given values in the green material (4.25, 11.5) match these combinations, option (A) is not the correct answer.
Now let's try option (B) Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Jeremy needs 30 gallons of brown material, then A would be 30. Let's see if this fits:
A + C = 78
30 + C = 78
C = 78 - 30
C = 48
Now, let's check if this aligns with the green material:
4.25 + B + D + 11.5 = C
4.25 + B + D + 11.5 = 48
Now, B and D must be positive values, and they need to sum up to 48 - (4.25 + 11.5) = 32.25.
One combination for B and D that satisfies this is B = 20 and D = 12.25.
Since the values 20 and 12.25 are among the given green material values, option (B) is the correct answer.
So, Jeremy will need 30 gallons of brown material and 18 gallons of green material.
Therefore, the correct choice is:
Jeremy will need 30 gallons of brown material and 18 gallons of green material.

Answer:
y = 3/4x -1/4
Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:
✅ Y = 3/4x - 1/4

The y-intercept is (12,0).
The x-intercept is (0,2).
Step-by-step explanation:
X & Y intercepts.• The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
• These can be easily found by rearranging the equation to standard slope format and plugging 0 into either variable.
Rearrange the equation to y = mx+ b.• -24x - 4y = -48.
• -4y = -48 + 24x.
• Divide the entire equation by -4 to isolate y.
• Y = 12 - 6x.
• Plug 0 into x
○ Y = 12 - 6(0).
○ Y = 12.
• Plug 0 into y
○ 0 = 12 - 6x
○ 6x = 12
○ X = 2
The x intercept is (0,2)
The y intercept is (12,0)

The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
Answers
The probability of landing on yellow is less than the probability of landing on blue.
Explanation:
The probability of landing on yellow is 2/8, while the probability of landing on blue is 3/8. 2/8 is less than 3/8
None of the other answers can be right, because:
the probability of landing on purple (2/8) is greater than the probability of landing on orange (1/8),
the probability of landing on orange (1/8) is less than the probability of landing on yellow (2/8),
and the probability of landing on purple (2/8) is less than the probability of landing on blue (3/8)
what is the equation of the line slope intercenpt form that passes through the point (8,9) and is parallel to the graph of y=3/4x-2? please explain.
Answers
Answer:
Slope-intercept form is y= 4x - 30
Step-by-step explanation:
Step 1: Substitute the slope from original line into the equation of the line
Here slope , m is 4
y= mx +b
where m is the slope
b is the y intercept
So Substituting slope we get,
y= 4x +b--------------------------------------------(1)
Step 2 :Substitute the given point (8,2) into the x and y values of equation (1)
y = 4x +b
2 =4(8) + b
Step 3: Solve for y intercept values
2 = 32+ b
2-32 =b
-30 =b
Now the y intercept value b= -30
Step 3: Substitute this value for 'b' in the slope intercept form equation
Substituting the value in eq (1) we get,
y= 4x +(-30)
y= 4x - 30
