As a result, 198 small bags and 92 big bags of popcorn were sold at the movie theatre.
what is equations ?An equation in mathematics is a claim that two statements are equivalent. It usually has two sections: a left and a right, separated by an equals sign in the middle. For instance, the statement that the expression 2x Plus 3 equals the expression 7 is represented by the equation 2x + 3 = 7. The equation can be used to determine the number of x that causes the equation to hold true when the variable x is unknown. Equations, such as linear equations, quadratic equations, trigonometric equations, and many others, can be used to explain a broad range of mathematical relationships.
given
Let x represent the quantity of big popcorn bags sold and y represent the quantity of small popcorn bags sold.
Based on the knowledge provided, we can create the following system of two equations:
x + y = 290 (the total amount of bags distributed) (the total number of bags sold)
4x + y = 566 (the entire revenue from popcorn sales) (the total revenue from popcorn sales)
We have two options for resolving the equation for x and y: substitution or removal. Here, we'll apply the replacement technique:
Y = 290 - x is the result of solving equation 1. We can enter the following formula in place of y in equation 2:
4x + (290 - x) = 566
If we simplify, we get:
3x + 290 = 566
290 from both parts are subtracted, giving us:
3x = 276
3 divided gives us:
x = 92
Thus, 92 big bags of popcorn were sold. We can change x = 92 into equation 1 to determine how many small packages were sold:
92 + y = 290
92 is subtracted from both parts to arrive at:
y = 198
Thus, 198 small packages of popcorn were sold.
As a result, 198 small bags and 92 big bags of popcorn were sold at the movie theatre.

Solve:
|3x|=9
x= 3
x= 1 and x=-2
x=3 and x=-3
x= 0 and x= 7
The required solutions of the equation |3x| = 9 are x = 3 and x = -3.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
We can solve the given equation by isolating the absolute value on one side and simplifying it.
|3x| = 9
| x | = 3
Now, we need to solve two separate equations for x:
When x is positive:
|x| = 3
=> x = 3 (since x is positive)
When x is negative:
|x| = 3
-x = 3 (since x is negative)
x = -3
Therefore, the solutions of the equation |3x| = 9 are x = 3 and x = -3.

The final RSVP guest count is 60 people Which catering company will offer the best deal for your family? How much money will your family save by choosing that company
a) The family's best deal is with Smokey's BBG which charges $780 for 60 guests.
b) Choosing Smokey's BBG over Bennie's BBQ will save (difference) the family $40.
How is the difference or saving determined?The total cost for each company's catering services is worked out using their cost functions.
Smokey's BBG does not charge a fixed cost, unlike Bennie's BBG.
The difference between the total costs of the companies is obtained by subtraction.
The number of guests = 60

Catering Fees $0 $100
Charge per person $13 $12
The total charge for 60 $780 ($13 x 60) $820 ($100 + $12 x 60)
Difference between the charges = $40 ($820 - $780)
However, using a system of equations we can determine the number of guests that makes the total cost the same for each company as 100.
Thus, comparing the total costs for the two companies shows the difference or cost savings to be gained by the family.

we will need at least 96 bags of sand to cover the base of the circular pool.
what is circle?
A circle is a two-dimensional geometric shape consisting of all the points that are equidistant from a given point, called the center.
The area of a circular pool with a diameter of 22 feet can be calculated using the formula:
A = πr^2
where A is the area of the circle, π is a constant (approximately equal to 3.14), and r is the radius of the circle (which is half the diameter).
In this case, the diameter is 22 feet, so the radius is:
r = d/2 = 22/2 = 11 feet
Now we can calculate the area of the circle:
A = πr^2 = 3.14 x 11^2 = 379.94 square feet (rounded to 2 decimal places)
To cover this area with sand, we need to know how many bags of sand are required. We are told that one bag of sand covers about 4 square feet, so we can calculate the number of bags of sand required as follows:
Number of bags = Area of pool / Area covered by one bag
Number of bags = 379.94 square feet / 4 square feet per bag
Number of bags ≈ 95 bags
Since we need to round up to a whole number of bags, we will need at least 96 bags of sand to cover the base of the circular pool.

right. The smallest rectangle measures 4 inches by 7 inches. If 2
inches are added to each dimension as the rectangles get larger, what is
the total area of the entire piece?
The total area of the rectangle with the provided figures will be equal to 280 inches.
How to obtain the area of the rectanglesNote that the area of a rectangle is length * width.
So, given this formula:
The area of the smallest rectangle will be: 4 * 7 = 28
The area of the next rectangle will be: (4 + 2) * (7 + 2)
= 6 * 9
= 54
The area of the next rectangle will be: (6 + 2) * (9 + 2)
= 8 * 11
= 88
The area of the fourth and largest rectangle will be: (8 + 2) * (11 + 2)
10 * 11
= 110
The total area of the angles will be: 28 + 54 + 88 + 110

Answer: The correct answer is yes, he brought enough money to get into the park.
Step-by-step explanation:
Well, let's analyze the information provided:
Admission to the amusement park for 8 students is $ 100. If each student agreed to share of cost equally, it means that we must divide those 100, for each of those students.
Therefore it will remain 100/8 = 12.5
If each student must pay 12.5, and Noah brought $ 13, that means he will have enough money to enter the park, and he will even have $ 0.50 left over.

The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions with a pH less than 7 are acidic, while solutiοns with a pH greater than 7 are basic οr alkaline.
