The senior class purchased pizza to sell after school for $320. If they sell pizza by the slice they make $2 per slice. If they sell a
whole pizza it's $10. Each pizza has 8 slices. Let u represent the number of slices sold and let y represent the number of whole
pizzas sold. If the class has 40 pizzas to sell, what is the greatest number of pizzas they can sell if they want to make a profit of
at least $140.
Answer:30
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
Why!
let x = number of slices sold
let y= number of pizzas sold
If you need to make a profit of at least 140 then you have to make what you paid + what you want = $320+$140 = $460
x= (40-y)8 = 320-8y : 40 is the number of pizza they bought &each pizza has 8 slices
2x + 10y ≥ 460
2 (320-8y) + 10≥460
Just solve it
180≥6y
30≥y
Therefore the greatest number of pizzas you can sell is 30 to make at least $140

What is a linear number equation ? I don’t understand
Answer:
How do you explain a linear equation?
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b. "Linear equation."
Step-by-step explanation:
In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.

Answer:
A regular polygon with an exterior angle measure of 140 degrees has nine sides
Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
-7m - 8 = m - 4
-15m = -4m
-8 - 3m = 4 - m
-8 - 7m = -4 + m
m - 4 = -7m - 8
-3m - 8 = 4 - m
Answer: answers are (-7m - 8 = m -4) and m - 4 = -7m -8. Hope this helps :)
Step-by-step explanation:
The expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2m - 5m - 8 = 3 + (-7) + m. The given expression will be solved as:-
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
We can also write the same equation in different ways:-
(-8 - 7m = -4 + m)
(m - 4 = -7m - 8)
Therefore, the expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).

X+ 3y = 9
2x+ y = -2
Solve for x and y
Answer:
(-3, 4)
Step-by-step explanation:
hey there,
< From the first equation, let's find x.
x + 3y = 9
x = 9-3y (I hope you understand how that works )
Next, we can substitute our equation that equals to x into the second equation.
2x + y = -2
2(9-3y) + y = -2 (I substituted "x" in "2x" with (9-3y))
Now, let's solve.
2(9-3y) + y = -2
18 - 6y + y = -2
-5y = -20
y = 4
Now that we have found what y is equal to, we can find x too. In the beginning we found that x = 9-3y so x = 9-3(4) = -3 >

the midpoint of AB is M(1,3).if the coordinates of A are(-1,5),what are the coordinates of B
Answer:
(3,1)
Step-by-step explanation:
let B be (x,y)
m(1,3)=midpoint
A(-1,5)=(x1,y1)
B(x,y)=(x2,y2)
(1,3)= x1+x2/2 y1+y2/2
(1,3)= -1+x/2 5+y/2
so,
-1+x/2=1 5+y/2=3
-1+x=2 5+y=6
x=3 y=1
therefore the co ordinates of B(x,y) are (3,1)
The co-ordinate points of B is (3,1)
What is midpoint in a line ?A midpoint in a given line segment divides the line segment in two equal parts.
In the given question
AB is a line segment.
Point A has co-ordinates (-1,5) and midpoint M has co-ordinates (1,3).
Assuming point B has co-ordinates (x,y)
We know midpoint formula is give by
M of x = (x₁ + x₂)/2 and M of y = (y₁ + y₂)/2
∴ 1 = (-1 + x₂)/2
2 = - 1 +x₂
x₂ = 3
And
3 = ( 5 + y₂)/2
6 = 5 + y₂
y₂ = 1
So the co-ordinate points of B(x₂,y₂) = (3,1)

Answer:
First one: Even
Second one: Neither
Third One: Odd
Fourth One: Neither
Step-by-step explanation:
The functions are:
a) f(x) = x² + 9 is neither even nor odd.
b) g(x) = |x - 3| is neither even nor odd.
c) f(x) = x is an odd function.
d) g(x) = x + x² is neither even nor odd.
Here, we have,
To determine whether each function is even, odd, or neither, we examine their symmetry properties under reflection about the y-axis (for even functions) and the origin (for odd functions).
Let's analyze each function:
a) f(x) = x² + 9
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
b) g(x) = |x - 3|
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
c) f(x) = x
This function is odd because it satisfies the property of symmetry under reflection about the origin. In other words, f(-x) = -f(x) for all x.
d) g(x) = x + x²
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
In summary:
a) f(x) = x² + 9 is neither even nor odd.
b) g(x) = |x - 3| is neither even nor odd.
c) f(x) = x is an odd function.
d) g(x) = x + x² is neither even nor odd.

An angle measures 44° less than the measure of its complementary angle. What is the measure of each angle?
a+b=90°
a=b+44°
b+44°+b=90°
2b+44°=90°
2b=90°-44°
2b=46°
b=23°
a=23°+44°
a=67°
The measure of each angle is 23° and 67°.
What is Angle?Angle is defined as the figure formed by the meeting of two lines or rays at a common point.
Complementary angles are those angle whose angle measures sum up to 90°.
Given that two angles are complementary and one of the angle's measure is 44° less than the measure of other one.
Let x be the measure of first angle.
Then x - 44 is the measure of the other angle.
x + (x - 44) = 90°
2x - 44 = 90
2x = 90 + 44
2x = 134
x = 134 / 2
x = 67
One of the measure of angle is 67°.
Measure of other angle = x - 44 = 67 - 44 = 23°
Hence the angle measures are 23° and 67°.

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. Problems- 85 degrees 5x degrees 5x degrees 5x+5 degrees 5x-10 degrees PLEASE HELP!
Answer:
The measure of x is 23 degrees
Step-by-step explanation:
Here, given the values of the angles of a polygon and the total of these angles, we want to find the value of the variable x attached to these angles;
Mathematically;
85 + 5x + 5x + 5x + 5 + 5x -10 = 540
85 + 5 -10 + 5x + 5x + 5x + 5x = 540
80 + 20x = 540
20x = 540-80
20x = 460
x = 460/20
x = 23 degrees
One month, Ruby worked 7 hours more than Isaac, and George worked 3 times as many hours as Ruby. Together they worked 150 hours. How many total hours did they work? Send
Answer:
Issac worked 24.4 hrs, Ruby worked 31.4 hrs, and George worked 94.2 hours
Step-by-step explanation:
x= hours worked
Issac= x Ruby= (x+7) George= 3(x+7)
x+(x+7)+3(x+7) = 150 [distribute 3 to (x+7)]
x+(x+7)+(3x+21) = 150 [add from left to right]
5x+28 = 150 [subtract 28 from both sides]
5x = 122 [divide both sides by 5]
x=24.4
Now plug the x value back into Issac, Ruby, and George's equations:
Issac=x=24.4
Ruby=x+7=31.4
George=3(x+7)=94.2
Double check by adding all their work hours together

Answer:

Step-by-step explanation:
Angle FGE = [tex]180-(7x+18)[/tex] because angles on a straight line add up to 180 degrees.
Angle EFG = [tex]180-38-(180-(7x+18))=6x-10[/tex] (Angles in a triangle add up to 180)
[tex]180-38-\left(-7x+162\right)=6x-10[/tex]
[tex]180-38+7x-162=6x-10[/tex]
[tex]7x-20=6x-10[/tex]
Add 20 to both sides:
[tex]7x-20+20=6x-10+20[/tex]
[tex]7x=6x+10[/tex]
Subtract 6x from both sides:
[tex]7x-6x=6x+10-6x[/tex]
[tex]x=10[/tex]
Angle [tex]EFG=6x-10=6(10)-10=60-10=50[/tex]
When you calculate your net worth and file your taxes, good _______ is particularly important.
A. insurance
B. credit management
C. record keeping
D. communication
Answer: Record keeping
Step-by-step explanation:
A person's net worth is calculated as the total assets they own minus the total liabilities they owe. As such it will be very important to keep records so that you know what you own as well its value as well as what you owe as well.
Taxes are no different. The better the records you keep are, the more accurate your tax payments will be. Without proper records you could overpay taxes which would mean you lose money or you could underpay taxes which is a crime.
