What's the answer, "If 84 cookies will serve 28 students, how many cookies are needed for 30 students" I need serious help!!!

Answers

Answer 1

Answer: For this question you will need to find out how many cookies each student eats. To find this, do 84 divided by 28. You will get 3. Since 28 is 2 less than 30, add 6 cookies for the two extra students. You will need 90 cookies.

Answer 2

Answer: First you need to figure out how many cookies will serve a single student.
You divide 84 by 28 and get 3.
So if 3 cookies serves an individual student, you multiply 3×30 and get 90. 90 cookies serve 30 students.

Rewrite by completing the square. 2x^2+7x+6=0

Answers

(2x + a)(x + b)

2b + a = 7
b*a = 6

factors of 6: (2x3) and (6x1)

let b = 2, a = 3

2(2)+ 3 = 7 check

(2x + 3)(x + 2)

Final answer:

To complete the square and rewrite the quadratic equation 2x^2+7x+6=0, follow these steps: move the constant term, divide the coefficient of x^2, square half of the coefficient of x, add the result to both sides, factor the left side, take the square root, and solve for x.

Explanation:

To rewrite the quadratic equation 2x^2+7x+6=0 by completing the square, follow these steps:

Move the constant term to the other side of the equation: 2x^2+7x = -6.
Divide the coefficient of x^2 by 2: x^2+(7/2)x = -3.
Take half of the coefficient of x and square it: (7/4)^2 = 49/16.
Add the result from step 3 to both sides of the equation: x^2+(7/2)x+49/16 = -3+49/16.
Factor the left side of the equation: (x+7/4)^2 = (1/16).
Take the square root of both sides of the equation: x+7/4 = ±(1/4).
Solve for x: x = -7/4 ±(1/4).

Y=2x+4
y=x=6
i need help solving the system of equations

Answers

Answer:

X = 6

Y = 6

Step-by-step explanation:

y = x = 6

we won’t pay attention to the first equation because this equation says that: “y = x” and “x = 6”

so, if x = 6, so will be y

Final answer:

The solution to the system of equations y = 2x + 4 and y = x + 6 is x = 2 and y = 8.

Explanation:

To solve a system of equations, you need to find the intersection point between the graphs of the two equations. The equations presented here are y = 2x + 4 and y = x + 6. However, there seems to be a typo in the question; presumably, the second equation should read y = x + 6 instead of y = x = 6.

To solve, we will set the two equations equal to each other and solve for x:

2x + 4 = x + 6

If we subtract 'x' from both sides of the equation, we get:

x + 4 = 6

Subtract '4' from both sides:

So, x = 2

Substitute x = 2 into the first equation to solve for y:

y = 2*2 + 4 = 4 + 4 = 8

Hence, the solution to the system of equations is x = 2, y = 8.
