To solve the inequality 3x - 2 > 2x - 7, we can start by subtracting 2x from both sides of the inequality:
3x - 2 - 2x > 2x - 7 - 2x
x - 2 > -7
Next, we can add 2 to both sides of the inequality:
x - 2 + 2 > -7 + 2
x > -5
The solution set can be graphed on a number line. We draw an open circle at -5 and shade to the right, indicating that x is greater than -5.
The solution set in interval notation is (-5, ∞).

To solve the inequality (3/4)x > 5, we can multiply both sides of the inequality by 4/3 (the reciprocal of 3/4). However, since we are multiplying by a negative number, we need to reverse the inequality sign:
(3/4)x * (4/3) < 5 * (4/3)
x < 20/3
To find the solution set in interval notation, we can write the fractional value 20/3 as a mixed number: 6 2/3.

To solve the inequality 7(3x + 11) < 7, we can start by simplifying both sides of the inequality:
21x + 77 < 7
Next, we can subtract 77 from both sides of the inequality:

Finally, we divide both sides of the inequality by 21:
21x/21 < -70/21

Apologies for the confusion. Let's go through the inequality one more time.
To solve the inequality 7(3x + 11) < 7, we can begin by simplifying the left side of the inequality:
21x + 77 < 7
Next, we can subtract 77 from both sides:
21x < 7 - 77
21x < -70
To isolate x, we divide both sides of the inequality by 21. However, we need to reverse the inequality sign since we are dividing by a negative number:
x > -70/21
The solution set can be graphed on a number line. We will use an open circle at -70/21 and shade to the right to indicate that x is greater than -70/21.
The solution set in interval notation is (-70/21, ∞).

Let's solve the inequality step by step:
-5(x-2)-5x < -(5x+4)+2x
First, distribute the -5 on the left side and the -1 on the right side:
-5x + 10 - 5x < -5x - 4 + 2x
Combine like terms:
-10x + 10 < -3x - 4
Next, bring all the variables to one side of the inequality by adding 10x and 3x to both sides:
-10x + 10 + 10x + 3x < -3x - 4 + 10x + 3x
13x + 10 < 13x - 4
Simplify:
13x < 13x - 14
Now, let's subtract 13x from both sides to isolate the variable:
13x - 13x < 13x - 13x - 14
0 < -14
The inequality 0 < -14 is false since 0 is not less than -14. Therefore, there is no solution.
Thus, the solution set is the empty set or {}, and there is no graph to represent on a number line. In interval notation, we would write the solution set as Ø.
-5(x-2)-5x < -(5x+4)+2x
First, distribute the -5 on the left side and the -1 on the right side:
-5x + 10 - 5x < -5x - 4 + 2x
Combine like terms:
-10x + 10 < -3x - 4
Next, bring all the variables to one side of the inequality by adding 10x and 3x to both sides:
-10x + 10 + 10x + 3x < -3x - 4 + 10x + 3x
13x + 10 < 13x - 4
Simplify:
13x < 13x - 14
Now, let's subtract 13x from both sides to isolate the variable:
13x - 13x < 13x - 13x - 14
0 < -14
The inequality 0 < -14 is false since 0 is not less than -14. Therefore, there is no solution.
Thus, the solution set is the empty set or {}, and there is no graph to represent on a number line. In interval notation, we would write the solution set as Ø.

Apologies for the incorrect response. Let's solve the inequality again:
-5(x-2) - 5x < -(5x+4) + 2x
First, distribute the -5 on the left side and the -1 on the right side:

-10x + 10 + 10x + 3x < -3x - 4 + 10x + 3x
3x + 10 < 7x - 4
Now, subtract 3x from both sides:
3x - 3x + 10 < 7x - 3x - 4
10 < 4x - 4
Next, isolate the variable by adding 4 to both sides:
10 + 4 < 4x - 4 + 4
14 < 4x
Finally, divide both sides by 4 (positive number, so the inequality sign remains the same):
14/4 < 4x/4
7/2 < x

-10x + 10 + 10x + 3x < -3x - 4 + 10x + 3x
3x + 10 < 7x - 4
Now, subtract 3x from both sides:
3x - 3x + 10 < 7x - 3x - 4
10 < 4x - 4
Next, isolate the variable by adding 4 to both sides:
10 + 4 < 4x - 4 + 4

Let's assume the width of the rectangle is denoted by "w".
The formula for the perimeter of a rectangle is P = 2(l + w), where "l" is the length and "w" is the width.
Given that the length is 40 centimeters and the perimeter is no greater than 140 centimeters, we can set up the following inequality:
2(40 + w) ≤ 140
Now, let's simplify the inequality:
80 + 2w ≤ 140
Subtracting 80 from both sides:
2w ≤ 60
Next, divide both sides by 2 to isolate "w":
w ≤ 30
Therefore, the maximum width of the rectangle must be 30 centimeters or less.

Certainly!
We have the inequality 2(40 + w) ≤ 140, which represents the perimeter of the rectangle being no greater than 140 centimeters.
To solve for the maximum width of the rectangle, we want to isolate the variable "w" by simplifying the inequality.
First, we distribute the 2 to both terms inside the parentheses:
80 + 2w ≤ 140
Next, we subtract 80 from both sides of the inequality to move the constant term:
2w ≤ 60
To solve for "w", we divide both sides of the inequality by 2:
w ≤ 30
This means that the width of the rectangle must be less than or equal to 30 centimeters in order for the perimeter to be no greater than 140 centimeters.
Therefore, the maximum width of the rectangle is 30 centimeters.

Apologies for not providing a specific number earlier.
To find the maximum width, we can substitute the given length and inequality into the formula for perimeter:

Now, distribute the 2:
80 + 2w ≤ 140

Let's assume the number of people they invite is denoted by "p".
The total cost of the reception will include the cleanup fee plus the cost per person multiplied by the number of people:
Total Cost = Cleanup Fee + (Cost per person) x (Number of people)
In this case, the cleanup fee is $80 and the cost per person is $38.
So, the equation becomes:
Total Cost = $80 + $38 x p
According to the budget, the total cost should not exceed $4,000. Therefore, we can create the following inequality:
$80 + $38 x p ≤ $4,000
To find the greatest number of people they can invite within their budget, we need to solve this inequality for "p".
First, let's subtract $80 from both sides of the inequality:
$38 x p ≤ $4,000 - $80
$38 x p ≤ $3,920
Dividing both sides of the inequality by $38:
p ≤ $3,920 / $38
p ≤ 103.157, approximately
Since they cannot invite a fraction of a person, the greatest number of people they can invite while staying within their budget is 103 people.
