the perimeter is at least 18 feet. Write and solve inequality that represents x
The inequality that represents x is [tex]$x \geq 6$[/tex]. This means that the total length of all the sides of the shape must be at least 6 feet.
Let's say the total length of all the sides of the shape is represented by the variable x. We are given that the perimeter is at least 18 feet. This can be written as an inequality: [tex]$x \geq 18$[/tex]
Since the sides of the triangle measure 3 feet, 5 feet and x-2 feet, we can express the perimeter inequality in terms of x as: [tex]$x+ 3 + 5 +x-2 \geq 18$[/tex]
Simplifying the left side of the inequality, we get: [tex]$2x + 6 \geq 18$[/tex]
Subtracting 6 from both sides, we obtain: [tex]$2x \geq 12$[/tex]
Dividing both sides by 2, we get: [tex]x \geq 6$.[/tex]

Which system of inequalities is shown in the graph?
The system of the inequalities is y ≥ 2x - 2, y ≥ x - 3x. Option B
How to determine the inequalitiesTo determine a system of inequalities graphically, plot each inequality on the same coordinate plane.
Represent each inequality as a boundary line (dashed or solid, depending on the inequality sign) and shade the region that satisfies the inequality. The solution area is the overlapping shaded region where all inequalities intersect.
The points within this shared region satisfy all the given inequalities simultaneously. If there is no intersection or common shaded area, the system has no solution that satisfies all the inequalities simultaneously.
So, we have that;
y ≥ 2x - 2
y ≥ x - 3x

ou work at the Peacock Blue store 40 hours/week over five days at a rate of $10.25/hour. Deductions are FICA (7.65%), federal withholding (15%), and state withholding (10%). Your expenses are transportation at $5.25/day, lunch at $3.85/day, and black slacks required for work at $19.95. How much is your discretionary income for one week?
Answer:
$210.69
Step-by-step explanation:
Firstly, just calculate how much money you earn:
40 * 10.25 = $410
Your transportation expenses = 5.25 * 5 = $26.25
Your lunch expenses = 3.85 * 5 = $19.25
Expenses for black slacks = $19.95
FICA = 7.65/100 * 410 (money you earned) = $31.365
Federal withholding = 15/100 * 410 = $61.5
State withholding = 10/100 * 410 = $41
Your discretionary income = 410 - (26.25 + 19.25 + 19.95 + 31.365 + 61.5 + 41) = $210.69

The price of a Barry bonds baseball card in 2001 was $50. It is now being sold for $30. Find the percent decrease in the cost of the card
Final answer:
The percent decrease in the cost of the Barry Bonds baseball card is 40%.
Explanation:
To calculate the percent decrease in the cost of the card, we can use the formula:
Percent decrease = ((original value - new value) / original value) * 100
In this case, the original value of the card was $50 and the new value is $30. Plugging in these values into the formula:
Percent decrease = ((50 - 30) / 50) * 100 = (20 / 50) * 100 = 0.4 * 100 = 40%
Therefore, the percent decrease in the cost of the card is 40%.

What’s 22.5 as a fraction in simplest form
Answer:
22.5% = 9/40 as a fraction
Step by Step Solution
To convert 22.5 percent to a fraction follow these steps:
Step 1: Write down the percent divided by 100 like this:
22.5% = 22.5/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
22.5/100 = (22.5 x 10)/(100 x 10) = 225/1000.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25. So,
(225÷25)/(1000÷25) = 9/40 when reduced to the simplest form.
Step-by-step explanation:
Answer:
9/4, or 2 1/4 is your answer
Step-by-step explanation:
Note that 22 is a whole number, and that 5 is a decimal.
Change the decimal into a fraction. To do so, move the decimal point to the right two place values and set the number over 100
22.5 = 225/100
Simplify.
(225/100)/(25/25) = 9/4
9/4, or 2 1/4 is your answer

-5(3x^2+5x+b)=ax^2-25x+45
Answer:
a = - 15 and b = - 9
Step-by-step explanation:
distribute the left side
- 15x² - 25x - 5b
For - 15x² - 25x - 5b = ax² - 25x + 45
Then the coefficients of like terms must be equal, hence
comparing coefficients of x² term ⇒ a = - 15
comparing constant term ⇒ - 5b = 45 ⇒ b = - 9
Answer: a = -15, b = -9
Step-by-step explanation:
-5(3x² + 5x + b) = ax² - 25x + 45
-15x² - 25x - 5b = ax² - 25x + 45 distributed -5 on left side
Notice that the middle terms (-25x) are equal, so the the remaining terms will also be equal.
-15x² = ax² ⇒ -15 = a
-5b = 45 ⇒ b = -9
Man can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?
Answer:
one box of crackers costs $0.70
Step-by-step explanation:
Let $x be the price of 1 container of yogurt and $y be the price of 1 box of crackers.
1. Man can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. 4 containers of yogurt cost $4x and 3 boxes of crackers cost $3y. In total,
[tex]3x+4y=9.55.[/tex]
2. Man can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. 2 containers of yogurt cost $2x and 2 boxes of crackers cost $2y. In total,
[tex]2x+2y=5.90.[/tex]
3. Solve the system of two equations:
[tex]\left\{\begin{array}{l}3x+4y=9.55\\2x+2y=5.90\end{array}\right.[/tex]
Multiply the second equation by 2 and subtract it from the first equation:
[tex]3x+4y-2(2x+2y)=9.55-5.90\cdot 2,\\ \\3x+4y-4x-4y=9.55-11.80,\\ \\-x=-2.25,\\ \\x=\$2.25.[/tex]
Then
[tex]2\cdot 2.25+2y=5.90,\\ \\2y=5.90-4.50,\\ \\2y=1.40,\\ \\y=\$0.70[/tex]
By setting up a system of equations and using elimination, we find that one box of crackers costs $2.25.
To solve the cost of one box of crackers, we need to set up two equations based on the information given:
4y + 3c = $9.552y + 2c = $5.90We use 'y' to represent the cost of one container of yogurt and 'c' for the cost of one box of crackers. To find the value of 'c', we can use substitution or elimination.
Let's eliminate 'y' by multiplying the second equation by 2, which gives us 4y + 4c = $11.80. Subtracting the first equation from this, we get:
c = $11.80 - $9.55
c = $2.25
So, one box of crackers costs $2.25.
After changing its format, a radio station lost 34% of its listeners. If there were an estimated 83,000 listeners orginally, how many listeners does the radio station have now?
Final answer:
The radio station has 54,780 listeners now.
Explanation:
To find the number of listeners the radio station has now, we need to calculate the number of listeners it lost after changing its format. If the station lost 34% of its listeners, we can calculate the number of lost listeners by multiplying the original number of listeners by 0.34 (34%).
Lost Listeners = 83,000 * 0.34 = 28,220 listeners
To find the number of listeners the radio station has now, we subtract the lost listeners from the original number of listeners.
Number of Listeners Now = 83,000 - 28,220 = 54,780 listeners
What is the answer ?
Answer:
2y
Step-by-step explanation:
Simplifying
21x + -42y = 0
Solving
21x + -42y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '42y' to each side of the equation.
21x + -42y + 42y = 0 + 42y
Combine like terms: -42y + 42y = 0
21x + 0 = 0 + 42y
21x = 0 + 42y
Remove the zero:
21x = 42y
Divide each side by '21'.
x = 2y
Simplifying
x = 2y

Write a number in which the value of the 3 is 10 times the value of the digit 3 in 156.32
Answer:
1563.2
Step-by-step explanation:
If you just multiply 0.3 by 10 you will get 3
Now all you need to do is write 3 or have a number which has unit place value of 3
Answer: The number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3
Step-by-step explanation:
The given number = 156.32
The place value of 3 in 156.32 is 3 tenth [since it the left most number after the decimal].
3 tenth can be written as [tex]\frac{3}{10}[/tex]
The number 10 times [tex]\frac{3}{10}[/tex]= [tex]10\times\frac{3}{10}[/tex]
Therefore, The number 10 times [tex]\frac{3}{10}[/tex]=3
Hence, the number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3
