6x^2+3x-63
Answer
Find out the how many cookies will each student get.
To prove
As given
mr.chan made 252 cookies for the annual fifth grade class bake sale .
they sold of them
Than
= 189
Number of cookies left after sold = 252 - 189
= 63
of the remaining cookies were given to P.T.A members .
Than
= 21
Number of cookies left after giving to P.T.A members = 63 - 21
= 42
As given
mr.chan allowed the 12 student helper to divide the cookies that are left equally.
= 3.5
Therefore the 3.5 cookies each student gets.
3¹/₂ or 3.5 cookies
Given:
Question:
How many cookies will each student get?
The Process:
Step-1
Then, let us create a suitable diagram as follows:
So, 1 unit of diagram is equal to 63 cookies.
Step-2
Then, let us create a suitable diagram as follows:
So, 1 unit of diagram is equal to 7 cookies.
Step-3
Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.
Let us calculate how many cookies will each student get.
The numerator and denominator are equally divided by 6.
Thus, each student will getcookies.
Keywords: Mr. Chan, made, 252 cookies, the Annual Fifth Grade Class Bake Sale, they sold 3/4 of them, 3/9 of the remaining, were given to, P.T.A members, allowed, the 12 student helper, to divide, left equally, how many, each student get

Group of answer choices
please help me!
A) (5,0.5)
B) (8,-1)
C) (-1,8)
D) (0.5,5)
What is the solution to the system of equations?
y=2x-3.5y = 2 x − 3.5
x-2y=-14x − 2 y = − 14
Group of answer choices
(10.5, 7)
(-7, 3.5)
(7, 10.5)
(3.5, -7)
Answer:
Step-by-step explanation:
1. You can use the expression for y to substitute into the first equation:
2x +4(1/4x -3) = 12
2x +x -12 = 12 . . . . . . eliminate parentheses
3x = 24 . . . . . . . . . . . add 12; next divide by 3
x = 8 . . . . . matches choice C
__
2. You can use the expression for y to substitute into the second equation:
x -2(2x -3.5) = -14
-3x +7 = -14 . . . . . . eliminate parentheses
21 = 3x . . . . . . . . . . add 3x+14; next divide by 3
7 = x . . . . . matches the third choice
_____
When the answer choices are sufficiently different, you only need to find one value to determine which is the correct choice. (If you want to check your work further, you can substitute the other answer value into the two equations to see if it works.)
The equation is solved and the mixed number is x = 30 4/5
Given data:
To solve the equation 5x/7 = 22, we need to isolate the variable x.
We can start by multiplying both sides of the equation by 7 to eliminate the fraction:
(5x/7) * 7 = 22 * 7
This simplifies to:
5x = 154
To solve for x, we can divide both sides of the equation by 5:
(5x)/5 = 154/5
x = 30.8
The solution as a mixed number is represented as:
x = 30.8 can be written as 30 and 4/5 in mixed number form.
Hence, the correct mixed number solution is x = 30 4/5.
