Answer:
First Equation: One Solution
Second Equation: Infinite Solutions
Third Equation: One Solution
Step-by-step explanation:
Let's solve these equations step by step.
\(-2x+3=-3x+2\\\)
Subtract 2 and add 2x
\(1=-x\\x=-1\)
The only solution here is -1.
\(-2x+3=-2x+3\)
Anytime the equations are the same on both sides, we have infinite solutions.
Add 2x
\(3=3\)
Any value of x will satisfy this equation.
\(-2x+3=2x+3\)
Add 2x and subtract 3
\(4x=0\\x=0\)
The only solution here is 0.

part a. Gretchen is going to make a witch’s hat for Halloween. Her pattern consists of a right circular cone without a base attached to a circle with a hole cut out of the middle, as shown in attached pic. The hole is congruent to the base of the cone.
Gretchen plans to make the conical portion of her hat 18 inches tall with a base circumference of 5pi inches. What is the slant height of the conical portion of the witch hat if made according to Gretchen’s plan? Express your answer as a decimal to the nearest tenth.
part b. Gretchen’s completed hat looks great. Unfortunately, when she tries to put her hat on, she realizes it is too small! When she double checks the dimensions, she finds that they are exactly as she had planned so she must have measured incorrectly in the beginning. Not wanting to waste the great looking hat, she decides to use it to put candy in. How many cubic inches of candy will exactly fill the conical portion of the hat? Express your answer as a common fraction in terms of pi.
part c. If the brim of Gretchen’s hat is a ring that extends 4 inches out from the base of the conical portion, what is the area of the brim in square inches? Express your answer in terms of pi.
part d. Pick one question above and describe your strategy for solving.
The Halloween conical hat, with given height, circular base and brim
extension has the following calculated parameters;
Part a. The slant height is 18.2 inches
Part b. The volume of the cone is \(37\frac{1}{2} \cdot \pi\) in.³
Part c. The area of the brim, A = 36·π in.²
Part d. The area of the brim is found by subtracting the area of the base of the cone from the area covered by the perimeter of the brim
Reasons:
Known parameters;
Height of the conical portion, h = 18 inches
Base circumference, C = 5·π inches
Part a. Slant height of the conical portion; Required
Solution:
The circumference of a circle, C = 2·π·r
Therefore;
\(r = \dfrac{C}{2 \cdot \pi}\)
Which gives;
\(r = \dfrac{5 \cdot \pi}{2 \cdot \pi} = \dfrac{5}{2} = 2.5\)
Radius, r = 2.5 inches
According to Pythagoras's theorem, we have; s² = r² + h²
Where;
s = The slant height of the cone
s² = 2.5² + 18² = 330.25
s = √(330.25) ≈ 18.2
The slant height, s ≈ 18.2 inchesPart b. The measure in cubic inches of candy that exactly fills the conical portion of the hat is the volume of the cone.
\(Volume \ of \ a \ cone = \dfrac{1}{3} \cdot \pi \cdot r^2 \cdot h\)
Therefore;
\(V = \dfrac{1}{3} \times \pi \times 2.5^2 \times 18 = 37\frac{1}{2} \cdot \pi\)
The volume of the cone, V = \(37\frac{1}{2}\)·π in.³Part c. The extension of the brim from the base of the cone = 4 inches
The radius of the brim, R = Radius of the base of the cone + 4 inches
∴ R = 2.5 inches + 4 inches = 6.5 inches
Area of the brim, A = Area of the 6.5 inch circle - Area of the circular base of the cone
∴ A = π × 6.5² - π × 2.5² = 36·π
The area of the brim, A = 36·π in.²Part d. The procedure for solving the question in part c, is described as follows;
The area of the brim can be found by finding the entire area of the circle formed by the perimeter of the brim, then subtracting the area of the base of the cone from that area.Learn more here:

Natalie is selling fruit at the Saturday market. She has a
otal of 48 pears that she wants to sell. She makes bags of
pears and sells them for $5 per bag. In which equation
oes b represent the number of bags of pears?
If Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
To represent the number of bags of pears, b, that Natalie sells at the Saturday market, we can use the following equation:
b = total_number_of_pears / pears_per_bag
In this equation, "total_number_of_pears" represents the total quantity of pears Natalie has, and "pears_per_bag" represents the number of pears she puts in each bag.
Given that Natalie has a total of 48 pears, we can substitute the value into the equation:
b = 48 / pears_per_bag
Now, we need to determine the number of pears she puts in each bag. The information provided states that Natalie sells bags of pears, and each bag is sold for $5. However, the specific number of pears per bag is not given. To proceed, we need this information.
Let's assume that Natalie puts 4 pears in each bag. We can substitute this value into the equation:
b = 48 / 4
Simplifying the equation gives:
b = 12
So, if Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
It's important to note that the specific value of "pears_per_bag" will affect the final result. If Natalie puts a different number of pears in each bag, the equation will yield a different number of bags sold.

The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question following:
8p - 3n + 4q - 9m
We have to determine the equivalent expression to the given expression
