Answer:
A : 428 ≤ 28x+42y B : 5.5238 trays
Step-by-step explanation:
X stands for # of pans of chicken and y stands for # of pans of wraps. Multiply 28 by 7 pans to get 196. then subtract the total guests by 196 to get 232. then divide that by how many a turkey wrap tray feeds so you get 5.5238
Final answer:
To ensure at least 428 guests are fed, using the given food pan capacities, Sabrina must prepare at least 6 trays of turkey wraps if she already plans on preparing 7 pans of chicken, according to the inequality 28x + 42y ≥ 428.
Explanation:
To solve this problem, we need to approach it in two parts. Let's tackle each part systematically.
Part A: Writing the Inequality
Let's let x represent the number of pans of chicken and y represent the number of trays of turkey wraps. Given that a pan of chicken feeds 28 guests and a tray of turkey wraps feeds 42 guests, and we need to feed at least 428 guests, we can write the following inequality:
28x + 42y ≥ 428
Part B: Finding the Minimum Number of Turkey Wraps Required
Given Sabrina prepares 7 pans of chicken, we need to find the minimum number of turkey wraps required. Substituting x = 7 into our inequality gives us:
28(7) + 42y ≥ 428
Solving for y gives:
196 + 42y ≥ 428
42y ≥ 232
y ≥ 5.5238
Since Sabrina cannot prepare a fraction of a tray, she must prepare at least 6 trays of turkey wraps to meet the minimum requirement, ensuring she has enough food to feed at least 428 guests.

Step-by-step explanation:
The teachers equation is:
[tex]-10x-7y=5[/tex]
[tex]12x-8y=-4[/tex]
If a row operation on the teacher's equation results in any of the system of the students' equation then the two systems are equivalent and will have the same solution.
For instance:
Let's maintain the bottom equation and add both equation to replace the top equation:
[tex]-10x+12x-7y-8y=5+-4\\12x-8y=-4[/tex]
This results in Khaled's equation:

Answer: [tex]average\ rate\ of\ change\approx-3[/tex]
Step-by-step explanation:
For this exercise you need to use the following formula:
[tex]average\ rate\ of\ change=\frac{f(b)-f(a)}{b-a}[/tex]
You need to find the average rate of change of the given function g(x) over the following interval:
[tex][-1,2][/tex]
So, you can see in the table that the point whose x-coordinate is -1, is:
[tex](-1,5)[/tex]
And the point whose x-coordinate is 2, is:
[tex](2,-3)[/tex]
Knowing this, let be:
[tex]a=-1\\f(a)=5\\\\b=2\\f(b)=-3[/tex]
Now you can substitute values into the formula:
[tex]average\ rate\ of\ change=\frac{-3-5}{2-(-1)}[/tex]
Finally, evaluating, you get that the average rate of change over the interval indicated in the exercise, is:
[tex]average\ rate\ of\ change=\frac{-8}{3}\\\\average\ rate\ of\ change=-2.66\\\\average\ rate\ of\ change\approx-3[/tex]

Identify the formula for finding the nth term of an arithmetic sequence, where A(n) is the nth term of an arithmetic sequence, a is the first term,n is the term number and d is the common difference.
Option D: A(n) = a + (n – 1) d
Solution:
To identify the formula for finding the nth term of an arithmetic sequence.
Let a be the first term.
d be the common difference of the each term.
n be the term of the number.
A(n) be the nth term of the arithmetic sequence.
Arithmetic formula:
A(n) = a + (n – 1) d
Example: 1, 4, 7, 10, 13, 16, 19, ...
This is a arithmetic sequence.
a = 1, d = 4 – 1 = 3.
To find the 5th term:
Substitute this in the above formula, we get
A(n) = a + (n – 1) d
A(5) = 1 + (5 – 1) 3
= 1 + 4(3)
= 1 + 12
A(5) = 13
In the given sequence 5th term is 13.
Hence Option D is the correct answer.
A(n) = a + (n – 1) d
Answer:
A(n) = a + (n - 1)d

Fina wants to use substitution to solve the system of equations. explain what she needs to do before using substitution. then solve the system of equations:
2x - y = 3
-1.5x + 3y = -18
To solve the system of equations using substitution, Fina needs to isolate one variable and substitute it into the other equation. The solution to the system of equations is x = -3 and y = -9.
Explanation:To solve this system of equations using substitution, Fina needs to isolate one variable in one of the equations and then substitute that expression into the other equation.
Here are the steps:
Choose one equation and isolate one variable. Let's isolate x in the first equation: 2x - y = 3. Add y to both sides: 2x = y + 3 and divide by 2: x = (y + 3)/2.
Substitute the expression for x in the other equation. Replace x in the second equation with (y + 3)/2: -1.5((y + 3)/2) + 3y = -18.
Solve the equation for y. Simplify the equation: -1.5y - 4.5 + 3y = -18. Combine like terms: 1.5y - 4.5 = -18. Add 4.5 to both sides: 1.5y = -13.5. Divide by 1.5: y = -9.
Substitute the value of y back into the expression for x to find its value. Replace y in x = (y + 3)/2 with -9: x = (-9 + 3)/2 = -6/2 = -3.
Therefore, the solution to the system of equations is x = -3 and y = -9.
there are 56 fish in a tank and each fish is yellow blue or black.
There are six more yellow fish than blue fish, and 4 fewer blackfish than blue fish.
How many blue fish are in the tank.
A) 18
B) 22
C) 20
D) 27
Answer:
c?
Step-by-step explanation:
To find the number of blue fish, we set up an equation based on the given information, solving which indicates there are 18 blue fish in the tank (option A).
Explanation:The question is a word problem asking to find out the number of blue fish in a tank given the total number of fish and the relationships between the counts of different colored fish. We can set up algebraic expressions to solve for the number of blue fish. Let the number of blue fish be represented by x. According to the problem, there are six more yellow fish than blue, which we can express as x + 6. There are four fewer black fish than blue, which we can say is x - 4. The total number of fish is given as 56.
So, the equation we can set up is:
x + (x + 6) + (x - 4) = 56
Simplifying the equation, we get:
3x + 2 = 56
Solving for x, we subtract 2 from both sides to get:
3x = 54
And then divide by 3:
x = 18
Thus, there are 18 blue fish in the tank, which corresponds to option A.

The redwood national park is home to some of the largest trees in the world. Hyperion is the tallest tree in the park, with a height of approximately 379 feet. Tom wants to find the height of the tree in yards
Final answer:
To find the height of the tree in yards, divide the height in feet by 3, the conversion factor from feet to yards.
Explanation:
The Redwood National Park is home to some of the largest trees in the world, including Hyperion, the tallest tree in the park at approximately 379 feet. To find the height of the tree in yards, we can convert the height from feet to yards by using the conversion factor of 1 yard = 3 feet.
Height in yards = Height in feet / Conversion factor
Height in yards = 379 feet / 3 feet/yard
Height in yards = 126.33 yards
Therefore, the height of Hyperion is approximately 126.33 yards.

81 is 18% of what number?
Answer:
n = 450
Step-by-step explanation:
18%·n = 81
18·n/100 = 81
18n = 8100
n = 8100 : 18
n = 450
Answer:
81 is 18% of 450.
Step-by-step explanation:
81 ÷ 18 = 4.5
4.5 x 100 = 450
450 - 18% = 369
450 - 369 = 81
So, 18% of 450 is 81 and 81 is 18% of 450.

A waitress sold 11 ribeye steak dinners and 12 grilled salmon dinners, totaling $560.63 on a particular day. Another day she sold 16 ribeye steak dinners and 6 grilled salmon dinners, totaling $584.46. How much did each type of dinner cost?
The cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20
Solution:
Let "a" be the cost of each ribeye steak dinners
Let "b" be the cost of each grilled salmon dinners
A waitress sold 11 ribeye steak dinners and 12 grilled salmon dinners, totaling $560.63 on a particular day
Thus we frame a equation as:
11 x cost of each ribeye steak dinners + 12 x cost of each grilled salmon dinners = 560.63
[tex]11 \times a + 12 \times b = 560.63[/tex]
11a + 12b = 560.63 -------- eqn 1
Another day she sold 16 ribeye steak dinners and 6 grilled salmon dinners, totaling $584.46
Thus we frame a equation as:
16 x cost of each ribeye steak dinners + 6 x cost of each grilled salmon dinners = 584.46
[tex]16 \times a + 6 \times b = 584.46[/tex]
16a + 6b = 584.46 ------------ eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 2 by 2
32a + 12b = 1168.92 ------- eqn 3
Subtract eqn 1 from eqn 3
32a + 12b = 1168.92
11a + 12b = 560.63
( - ) ----------------
21a = 1168.92 - 560.63
21a = 608.29
Divide both sides by 21
[tex]a = 28.96 \approx 29[/tex]
Substitute a = 29 in eqn 1
11(29) + 12b = 560.63
319 + 12b = 560.63
12b = 560.63 - 319
12b = 214.63
Divide both sides by 12
[tex]b = 20.13 \approx 20[/tex]
Thus cost of each ribeye steak dinner is $ 29 and cost of each grilled salmon dinner is $ 20
