Please explain your answer!!
Answers
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.

Your class at school has 18 girls and 12 boys. If your school had the same ratio throughout the whole school and there are 2000 students in the school, how many total girls are in your school?
Answers
The ratio of girls to boys in your class is 18 girls : 12 boys, or in fraction form 18/12 or 3/2.
If the school has the same ratio throughout, the ratio of girls to boys in the entire school is 3 girls to 2 boys.
To find the number of girls in the school, you can use the equation:
(number of girls) / (number of students) = (3 girls) / (5 students)
Cross-multiplying, we get:
(number of girls) = (3 girls) / (5 students) * (2000 students)
Simplifying, we get:
(number of girls) = 1200
So, there are 1200 girls in the school.

Let the cost of each car decal is d.
After applying a discount of $2 the total for 25 decals came to $250.
Set up an equation:
25(d - 2) = 250Solve it for d:
25(d - 2) = 250d - 2 = 250/25d - 2 = 10d = 10 + 2d = 12The normal cost of each decal is $12.

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)
