The solution to the inequality is 1 < x ≤ 8.
The given inequality can be split into two components:
The difference of 2x and 5 is greater than -3: This can be written as:
2x - 5 > -3
To solve for x, we first add 5 to both sides of the inequality:
2x > 2
Then, we divide both sides by 2:
x > 1
This indicates that the values of x which satisfy this part of the inequality are greater than 1.
The difference of 2x and 5 is less than or equal to 11: This can be written as:
2x - 5 ≤ 11
Adding 5 to both sides:
2x ≤ 16
Dividing both sides by 2:
x ≤ 8
Therefore, the common range that satisfies both parts is 1 < x ≤ 8.

Jimmy dean made 15 sausages in 3 hours. At this same rate , how many sausages did he make in 8 hours
Answer:
40
Step-by-step explanation:
15/3=5
5*8=40
Jimmy Dean would make 40 sausages in 8 hours, based on a calculation using his rate of sausage making determined from the 15 sausages he made in 3 hours.
Explanation:If Jimmy Dean made 15 sausages in 3 hours, we can calculate the rate at which he makes sausages and then use this rate to find out how many he would make in 8 hours. First, find the sausage-making rate by dividing the total sausages made by the total hours worked:
Rate = Total Sausages / Total Hours = 15 sausages / 3 hours = 5 sausages per hour
Next, we multiply this rate by the number of hours we are interested in, which is 8 hours:
Sausages in 8 hours = Rate * 8 hours = 5 sausages/hour * 8 hours = 40 sausages
Therefore, at the same rate, Jimmy Dean would make 40 sausages in 8 hours.
Hello ! Do you know the ways of arranging the letters in the word TOY?
Answer:201525
Step-by-step explanation:
In permutations, the order of items matters. The word 'TOY' can be arranged in 6 different ways, calculated using the formula: n!/(n-r)!.
Explanation:The student is asking a mathematical question related to permutations. Permutations refer to the arrangements of items where the order is important. In this instance, the student is interested in arranging the letters in the word 'TOY'. To calculate the number of ways to arrange these letters, we use the formula: n!/(n-r)!.

Suppose you bought supplies for a party. Three rolls of streamers and fifteen party hats cost $30. Later, you bought two rolls of streamers and four party hats for $11. Write and solve a system of equations to determine the cost of streamers and party hats, find their costs.
Final answer:
To determine the cost of streamers and party hats, a system of linear equations is created and solved. The streamers cost $2.50 each, and the party hats cost $1.50 each after solving the system by the elimination method.
Explanation:
To find the cost of streamers and party hats, we need to set up a system of linear equations based on the information provided. Let's denote the price of one roll of streamers as s and the price of one party hat as h.
From the first purchase:
3s + 15h = $30
From the second purchase:
2s + 4h = $11
Now, we'll solve the system using substitution or elimination method. For simplicity, we'll use the elimination method.
First, let's multiply the second equation by 3.75 to match the number of hats in the first equation:
7.5s + 15h = $41.25
Subtract the first equation from this new equation:
7.5s + 15h - (3s + 15h) = $41.25 - $30
4.5s = $11.25
s = $2.50
With the cost of a streamer found, substitute s = $2.50 into the second original equation:
2($2.50) + 4h = $11
$5 + 4h = $11
4h = $6
h = $1.50
Therefore, the cost of one roll of streamers is $2.50 and the cost of one party hat is $1.50.
Final answer:To determine the cost of streamers and party hats, a system of linear equations is created and solved. The streamers cost $2.50 each, and the party hats cost $1.50 each after solving the system by the elimination method.Explanation:To find the cost of streamers and party hats, we need to set up a system of linear equations based on the information provided.

Answer:
Therefore the price of an foundation drink is $ 3.20(approx).
Step-by-step explanation:
Let the price of one fountain drink be x and one beg of popcorn be y.
The Clayton family bought 4 fountain drinks and 3 begs of popcorn and paid $22.50. The Hanks family bought 5 fountain drinks and 2 begs of popcorn and paid $23.75.
According to the problem,
4x+3y=22.50..............(1)
5x+2y=23.75..............(2)
Equation (1)×5 - Equation (2)×4
20x+15y-(20x+8y)=112.5-91
⇔20x + 15y -20 x-8y=21.5
⇔7y=21.5
⇔y = 3.07
putting the value of y in equation (1)
4x+3×3.07 =22.50
⇔4x=22.50 -9.21
⇔x=3.20
Therefore the price of an foundation drink is $ 3.20(approx).

A football field is 120 yards long by 53 yards wide. What is the total area
Answer:
6360
Step-by-step explanation:
the steps is just 120 times 53 which equals 6360. area= length multiplied by width
The area of a football field that is 120 yards long and 53 yards wide is 98,304,000 square inches.
To calculate the total area of a football field that is 120 yards long and 53 yards wide, you can use the formula for the area of a rectangle, which is length× width.
Step 1: Identify the dimensions of the field. The football field is 120 yards long and 53 yards wide
Step 2: Convert the dimensions into a consistent unit of measure, such as feet. Since there are 3 feet in a yard, multiply each dimension by 3.
Length in feet: 120 yards× 3 feet/yard = 360 feet
Width in feet: 53 yards × 3 feet/yard = 159 feet
Step 3: Calculate the area in feet. Area = Length × Width.
Area = 360 feet × 159 feet = 57,240 square feet
Step 4: To get the area in square inches, recognize that there are 12 inches in a foot, so the area in square inch\
es is:
Area in square inches = 57,240 ft²× (12 inches/foot)² = 98,304,000 square inches.
This calculation shows that the total area of the football field is approximately 98,304,000 square inches.

The vertex is (-4, -52), and it represents the minimum for the function.
Step-by-step explanation:
Parallelogram ABCD has coordinates A(-1,10) B(2, -1) C(5,4) and D(-4,5). Find the coordinates of where diagonals AC and BD intersect at. Enter your answers as numbers.
The coordinates of where diagonals AC and BD intersect at O(2,7).
Step-by-step explanation:
We are given coordinates as A(-1,10) and C(5,4).And we know that the diagonals of parallelogram always bisect each other.
Let us consider O is the intersection point among the diagonals AC and BD. So, the point O bisects the line AC into two equal parts, and also it is the mid-point of AC.
We can find point O using the midpoint formula as,
O (x,y) = ([tex]\frac{(x1+x2)}{2}[/tex] , [tex]\frac{(y1+y2)}{2}[/tex])
= ([tex]\frac{(-1+5)}{2}[/tex] , [tex]\frac{(10+4)}{2}[/tex])
= ([tex]\frac{4}{2}[/tex], [tex]\frac{14}{2}[/tex])
= (2,7)
So Diagonals AC and BD intersects at the point O (2,7).
the three points (3, -5) , (-a+2,3) and (2a+3, 2) lie on the same line. what is a?
Answer:
a = -7/23.
Step-by-step explanation:
For them to lie on the same line the slope of the line joining the first 2 points must equal the slope of the line joining the second and third points.
so (3 - -5) / (-a+2 - 3) = (2 - 3) /[(2a + 3) - (-a + 2)]
8 / (-a - 1) = -1 / (3a + 1) Cross multiply:
-1(-a - 1) = 8(3a + 1)
a + 1 = 24a + 8
-7 = 23a
a = -7/23.
To find the value of a, we can set the slopes between pairs of points equal to each other and solve for a. The value of a is 14/13.
Explanation:To determine the value of a such that the points (3, -5), (-a+2,3), and (2a+3, 2) lie on the same line, we can use the slope formula. The slope between two points (x1, y1) and (x2, y2) is given by the formula: m = (y2 - y1) / (x2 - x1). We'll calculate the slopes for the two pairs of points and set them equal to each other to find a.
Let's start by finding the slope between the first two points: (-a+2, 3) and (3, -5).
The slope is: m1 = (3 - (-5)) / (-a+2 - 3), which simplifies to m1 = 8 / (-a-1).
Next, let's find the slope between the second and third points: (2a+3, 2) and (3, -5).
The slope is: m2 = (2 - (-5)) / (2a+3 - 3), which simplifies to m2 = 7 / (2a).
Setting the two slopes equal to each other, we have: m1 = m2. Plugging in the expressions for m1 and m2, we get: 8 / (-a-1) = 7 / (2a). To solve for a, we'll cross-multiply and simplify the equation.
After simplifying, we find that a = 14/13.

Find the surface area of the following triangular prism.
Answer: 144 ft squared
Step-by-step explanation:
Let's find the two bases first. They are triangles with a base of 6 and a height of 8. The formula for the area of a triangle is b * h * 1/2 = 6 * 8 * 1/2 = 24. There are two so you would do 24 * 2 which is 48.
Then let's find the area of the other three faces, all of which have a length of 4. One has a width of 8 so you would do 4 * 8 which is 32. Another has a width of 6 so you would do 4 * 6 which is 24. The last one has a width of 10 so you would do 4 * 10 which is 40.
Add up the areas of the two bases and three faces together:
48 + 32 + 24 + 40 = 144 ft squared

To find the volume of a cylinder in cubic inches, use the formula V = πr²h, where r is the radius of the base of the cylinder and h is the height of the cylinder.
Explanation:The equation for finding the volume V of a cylinder in cubic inches can be derived from the basic principle that the volume of a shape is equal to the area of its base multiplied by its height. For a cylinder, the base is a circle, and the area of a circle is given by the formula πr², where r is the radius of the circle.
Therefore, the volume of the cylinder is the area of its base times its height, which can be written as V = πr²h, where h is the height of the cylinder. By using this formula, you can calculate the volume of a cylinder if you know the radius of its base and its height.

[tex]\frac{9}{4}x-\frac{5}{6}=-\frac{13}{12} x[/tex] Subtract 9/4x on both sides
[tex]-\frac{5}{6} =-\frac{13}{12} x-\frac{9}{4} x[/tex] To combine fractions, the denominator has to be the same. They both have a least common denominator (LCD) of 12, so multiply -9/4x by 3/3 to make the denominator 12
