The ordered pairs that are solutions to the inequality 3x + 4y ≥ 12 are (8, -3), (0, 5), and (3, 2). The pair (-5, 2) does not satisfy the inequality and is not a solution.
To determine which ordered pairs are solutions to the inequality 3x + 4y ≥ 12, we can substitute the x and y values from each pair into the inequality and see if it holds true.
For (8, -3), we check if 3(8) + 4(-3) ≥12, which gives 24 - 12 ≥ 12, so 12 ≥ 12. This pair is a solution because the inequality is satisfied.For (-5, 2), we check if 3(-5) + 4(2) ≥ 12, which gives -15 + 8 ≥ 12, so -7 ≥ 12. This pair is not a solution because the inequality is not satisfied.For (0, 5), we check if 3(0) + 4(5) ≥ 12, which gives 0 + 20 ≥ 12, so 20 ≥ 12. This pair is a solution because the inequality is satisfied.For (3, 2), we check if 3(3) + 4(2) ≥ 12, which gives 9 + 8 ≥ 12, so 17 ≥ 12. This pair is a solution because the inequality is satisfied.Therefore, the solution pairs are (8, -3), (0, 5), and (3, 2).
a square room has a tile floor with a hundred square tiles how many tiles are along the edge of the room
The number of tiles along the edge of a square room with a hundred square tiles is 10.
First, we need to recognize that a square room means all sides are of equal length. Since the room is tiled with square tiles throughout, the number of tiles along one edge will be the same as the other.
If there are a hundred square tiles in total, this represents the area of the square which is the product of the lengths of its sides (since the area of a square is given by side x side).
To find the length of a side, we take the square root of the total number of tiles. In this case, the square root of 100 is 10.
Therefore, there are 10 tiles along the edge of the square room.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
1/2 ÷ 3
This expression situation can be represented as:
Half of the cake is left and the leftover cake is divided among 3 people.
The formula for dividing fractions.
= a/b ÷ c/d
= a/b x d/c
= (axd) / (bxc)
The solution for 1/2 ÷ 3.
= (1/2) / 3
= 1/(2x3)
= 1/6
Thus,
The 1/2 ÷ 3 situation that represents can be:

A man comes into a store and steals $100 from the register without the owner knowledge. Comes back and buys $70 worth of stuff and the owner gives him $30 in change. How much money did the owner lose
Answer
The owner lose is $100 .
Reason
As given
A man comes into a store and steals $100 from the register without the owner knowledge.
Comes back and buys $70 worth of stuff and the owner gives him $30 in change.
i.e First man steals $100 than give back to owner when he buys $70 worth of stuff and the owner gives him $30 in change.
Therefore the total owner lose is the sum of $70 worth of stuff and $30 in change.
Total owner lose = $70 + $30
= $100
Therefore the owner lose be $100 .
Hence proved
Use the distributive property to solve each problem 5x13
To solve 5x13 using the distributive property, we can distribute 5 to both terms inside the parentheses and simplify the expression.
Explanation:Using the distributive property, we can solve 5x13 as:
5x13 = (5 x 10) + (5 x 3)
= 50 + 15 = 65.

A fair coin is flipped 100 times and the results are recorded in the table below.
Which statement is correct?
A) The theoretical probability of the coin landing on heads is 7/20.
B) The experimental probability of the coin landing on tails is 1/2.
C) The theoretical probability of the coin landing on tails is 1/2.
D) The experimental probability of the coin landing on heads is 13/20.
Option C) is the correct statement as the Theoretical Probability of the coin landing on tails is 1/2
What do we mean by theoretical probability?Theoretical probability is the ratio of favorable outcomes to the total number of outcomes.
What do we mean by experimental probability?Experimental probability or empirical probability is based on a particular experiment using the same formula.
How do we determine probabilities by the question?Experimental probability of getting heads
= Frequency of heads/Total observations
= 35/100 = 7/20
Experimental probability of getting tails
= Frequency of tails/Total observations
= 65/100 = 13/20
The theoretical probability of getting a heads
= Favorable outcomes of getting heads/Total possible outcomes
= 1/2
The theoretical probability of getting a tails
= Favorable outcomes of getting tails/Total possible outcomes
= 1/2
When we cross-check with the options,
A) Incorrect, as the Theoretical Probability of the coin landing on heads = 1/2
B) Incorrect, as the Experimental Probability of the coin landing on tails = 13/20
C) Correct, as the Theoretical Probability of the coin landing on tails = 1/2
D) Incorrect, as the Experimental Probability of the coin landing on heads = 7/20

"Пятерку я получил не на третьем уроке" - ложь. Значит, пятерку Вася получил на третьем уроке.
"Четверку получил на втором" - тоже ложь. Значит, четверку Вася мог получить на перовом или на третьем уроке.
Выше мы выяснили, что на третьем уроке он получил пятерку, следовательно, четверку Вася получил на первом уроке.
Свободны остались только второй урок и тройка.

Five less than the product of a number n and -6 is at least 8.
A) 5-(-6n)≥8
B -n/6-5≥8
C) -6n-5≥8
The required inequality is -6n - 5 ≥ 8. Option (C) is correct.
What is inequality?Inequality shows relation between two expression which are not equal to each others.
Given that,
When 5 is subtracted from the product of number n and -6 is at least 8.
The product of number n and - 6 = -6n
Subtract 5 from product of number n and -6 = -6n - 5
To write the inequality that shows that 5 less than -6n is at least 8,
Implies that, -6n - 5 can be grater than or equal to 8.
The inequality can be expressed as,
-6n - 5 ≥ 8

What are two ways to find the total cost of a pair of shoes for $57 with a sales tax of 2%?
Answer:
The total cost is $58.14.
Step-by-step explanation:
Given : A pair of shoes for $57 with a sales tax of 2%.
To find : What are two ways to find the total cost ?
Solution :
Cost price CP=$57
Sales tax S=2%
One way :
The total cost is given by,
[tex]C=CP+2\%\text{ of } CP[/tex]
[tex]C=57+\frac{2}{100}\times 57[/tex]
[tex]C=57+1.14[/tex]
[tex]C=58.14[/tex]
The total cost is $58.14.
Another way :
Using selling price formula,
[tex]SP=\frac{100+S\%}{100}\times CP[/tex]
[tex]SP=\frac{100+2}{100}\times 57[/tex]
[tex]SP=1.02\times 57[/tex]
[tex]SP=58.14[/tex]
The total cost is $58.14.
