Which of the following would be a possible solution to the system of inequalities given below?
Answer:
(0,5)
Step-by-step explanation:
we have
[tex]2x+3y > 12[/tex] ----> inequality A
[tex]x-y\leq 1[/tex] ----> inequality B
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities of the system (makes true both inequalities)
Verify each ordered pair
Substitute the value of x and the value of y of each ordered pair in the inequality A and in the inequality B and then compare the results
case 1) (0,5)
For x=0,y=5
Inequality A

so
The ordered pair satisfy inequality B
therefore
The ordered pair would be a solution of the system
case 2) (5,2)
For x=5,y=2
Inequality A
[tex]2(5)+3(2) > 12[/tex]

54% of students in your class have move at least one time write this percent as a decimal
Answer:
n*54/100
Step-by-step explanation:
it depend on your class students number. if your class number is n, n*54/100 is your answer and it must be a natural number so u must rond it. for example if n was 20 so 20*54/100 = 10.8 that must rond it to number 10. 10 is the answer.
54% as a decimal is 0.54. This is found by converting the percent (per hundred) to the fraction 54/100, and then dividing the numerator by the denominator.
To write 54% as a decimal, you need to convert the percent into a fraction and then to a decimal. The word 'percent' means 'per hundred,' so 54% can be written as 54/100. To convert this fraction to a decimal, you divide the numerator by the denominator.
Here's the conversion step by step:
Write 54% as a fraction: 54/100.Divide 54 by 100: 54 ÷ 100 = 0.54.Therefore, 54% as a decimal is 0.54%.. This means that 54% of the students in the class have moved at least one time, which is equivalent to 0.54 when expressed as a

Rahmi bought 1 pair of jeans and 2 T-shirts. How much did rahmi spend? Write equations to solve. Use a letter to represent the unknown quantity
1x + 2y = (The answer/money spent)
The total cost that Rahmi spent can be represented by an equation c = j + 2t, with 'c' representing the total cost, 'j' the price of jeans, and 't' the price of a T-shirt. Actual costs can't be determined without specific prices.
Explanation:To figure out how much Rahmi spent, let's set up an equation with the unknown quantities. Let's assume the cost of one pair of jeans is represented by 'j' and the cost of one T-shirt is represented by 't'. Since Rahmi bought 1 pair of jeans and 2 T-shirts, the total cost, 'c', can be represented as:
c = j + 2t
Unfortunately, without specific prices for the jeans and the T-shirts, we cannot calculate the exact total cost. However, this equation will help Rahmi to determine the cost once the prices are known.

After solving n/8=9 you will get n = 72.
To solve the equation n/8 = 9 for n, we need to isolate the variable by performing inverse operations.
Step 1: Multiply both sides of the equation by 8 to eliminate the fraction:
8 * (n/8) = 8 * 9
This simplifies to n = 72.
Therefore, the solution to the equation n/8 = 9 is n = 72. When n is divided by 8, the result is 9. This means that 72 is the value that satisfies the equation and makes it true.

19=8+y solve for y? pleas ehelp me answer
Answer:
Step-by-step explanation:
8+?=19
19-8=11
Y=11
Final answer:
To solve the equation 19 = 8 + y for y, you subtract 8 from both sides which gives you y = 11.
Explanation:
The equation provided, 19 = 8 + y, is a simple linear equation where you are solving for the variable y. To find the value of y, you need to isolate y on one side of the equation.
Here is the step-by-step process:
Start with the original equation: 19 = 8 + y.
To isolate y, you need to get rid of the 8 on the right side of the equation. You can do this by subtracting 8 from both sides of the equation.
Subtracting 8 from both sides gives us: 19 - 8 = y.
Simplify the left side: 11 = y.
Therefore, y equals 11.

y = k/x
Where k is the constant of proportionality
When x = 3 and y = 5
5 = k/3
Cross multiply
k = 5×3
k = 15
The equation is y = 15/x
The given relationship Y varies inversely with X and when X is equal to 3, Y equals to 5 which leads us to the equation Y = 15/X which illustrates this inverse variation.
Explanation:The given question states that Y varies inversely with X and provides us with a pair of values - X = 3, Y = 5. In mathematics, when one quantity Y varies inversely as another X, it can be represented by the equation Y = k/X where k is the constant of variation. To find k, we will substitute the given X and Y values into the equation leading to 5 = k/3. Simplifying, we find k = 5*3, that is, k equals 15.

The sampling method most likely to result in self-selection bias is the voluntary response sample. It involves individuals choosing to respond to the survey and may result in a biased sample as those who participate may not represent the overall opinion of the student body.
Explanation:In the context of the homecoming dance committee's survey, the method that is most likely to result in self-selection bias is the voluntary response sample. This sampling method involves allowing individuals to choose to respond to the survey on their own. The bias comes from the fact that those who choose to respond may not be representative of the entire student body due to differences in interest or motivation related to the theme of the dance. For example, students with strong opinions on the theme or are more involved in the dance may be more likely to respond, leading to a self-selected and therefore potentially biased sample.
