You and your friend are selling magazine subscriptions for a fundraiser. After w weeks, you have sold (3w+8) subscriptions and your friend has sold (6w+6) subscriptions.
Answer:
3w-2
Step-by-step explanation:
Given that, after w weeks you sold (3w+8) subscriptions and your friend sold (6w+6) subscriptions.
So, the difference between the number of subscriptions your friend has sold and you have sold after w weeks = (6w+6)-(3w+8)
=6w+6-3w-8
=3w-2
Hence, the required expression is 3w-2.

Tell a folk story about the history of irrational numbers. Research what is known about irrational numbers, their development, and why they are important.
Answer:
The history of irrational numbers, The discovery of irrational numbers is usually attributed to Pythagoras, more specifically to the Pythagorean Hippasus of Metapontum, who produced a (most likely geometrical) proof of the irrationality of the square root of 2. The story goes that Hippasus discovered irrational numbers when trying to represent the square root of 2 as a fraction. However Pythagoras believed in the absoluteness of numbers, and could not accept the existence of irrational numbers. He could not disprove their existence through logic, but his beliefs would not accept the existence of irrational numbers and so he sentenced Hippasus to death by drowning. Irrational numbers are important because without it we wouldn't have the continuum of real numbers which would make geometry impossible to do in life.

Write the difference of the given functions (f - g)(x):
f(x) = x² + 2x - 6 and g(x) = x + 5.
Answer:
(f - g)(x) = x² + x - 11
General Formulas and Concepts:
Pre-Algebra
PropertiesAlgebra I
Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = x² + 2x - 6
g(x) = x + 5
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = x² + 2x - 6 - (x + 5)Distribute -1: (f - g)(x) = x² + 2x - 6 - x - 5Combine like terms: (f - g)(x) = x² + x - 11Which team has the best record? Explain how you know. a.

What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Let, The numerator of a fraction represents the number of games lost and the denominator represents the total number of games played.
Therefore, The fractions that represent this context for all the teams are,
1/3, 1/9, 1/4 and 1/10.
We know the value of a fraction increase with the same numerator and smaller and smaller denominator.
So, The fraction 1/10 has the least value which indicates that it is the best performer.

the sum of the interior angles in a pentagon
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540

8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe
Answer:
1/6
Step-by-step explanation:
ive seen that question b4
2 pounds of flour are required to make 1 recipe, as of the given condition.
Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.
Thus, 2 pounds of flour are required to make 1 recipe, as of the given condition.

A rental car company is running two specials. Customers can pay $50 to rent a compact car
for the first day plus $6 for each additional day, or they can rent the same car for $20 the
first day and $12 for every additional day beyond that. Nora notices that, given the number
of additional days she wants to rent the car for, the two specials are equivalent. How many
additional days does Nora want?
Write a system of equations, graph them, and type the solution
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5

2
3
4
6
please answer
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6
