If 11 is Subtracted from both sides, the resulting inequality is 9 > -4
How find the resulting inequality?
An inequality is a relationship that makes a non-equal comparison between two numbers or other mathematical expressions e.g. 2x > 4
Initially, you have 11 > −2
If you subtract 11 from both sides, you will have:
11 -2 > −2-2
9 > -4
Thus, the resulting inequality will be 9 > -4

vegetable garden for radishes. Kwan wants to know how much of the whole garden
he is using to plant radishes.
Kwan is utilizing 8% of the entire garden to plant radishes.
Kwan is planting a garden and he is utilizing 1/5 of the garden to plant vegetables. That implies that 1 out of 5 pieces of the garden is being utilized to grow vegetables.
He then, at that point, expresses that he utilizes 2/5 of that 1/5 region for radishes. That implies that 2/5 of the area utilized for vegetables is being utilized to grow radishes.
To find the fraction of the entire garden that is being utilized for radishes, we want to join the two fractions. We can do this by multiplying them together.
At the point when we multiply 1/5 by 2/5, we get 2/25. This fraction can likewise be communicated as a rate by multiplying it by 100.
2/25 * 100 = 8%

Mrs. Cooper paid more than $22 for a pack of hand towels. Each towel cost $2.85. The hand towels were available in packs of 4, 5, 6, and 8. Use the inequality to find the minimum number of towels, t, in the pack.
Using inequality, the minimum number of towels in the pack is t = 6.
How to Find Minimum Number Using Inequality?We can start by using the inequality 2.85t > 22, where t is the number of towels in the pack.
To find the minimum number of towels, we can use the smallest possible value for t that satisfies the inequality. Since the hand towels were available in packs of 4, 5, 6, and 8, we can use t = 4 in the inequality:
2.85(4) > 22
Simplifying the left side of the inequality gives:
11.4 > 22
This is not true, so t = 4 does not satisfy the inequality.
Next, we can use t = 5:
2.85(5) > 22
Simplifying the left side of the inequality gives:
14.25 > 22
This is also not true, so t = 5 does not satisfy the inequality.
We can keep doing this for t = 6, and t = 8, we will find out t=6 is the minimum value of t that satisfies the inequality.
2.85(6) > 22
Simplifying the left side of the inequality gives:
17.1 > 22
This is true, so t = 6 is the minimum number of towels in the pack.

1. Amanda goes to the bookstore and buys 4 comics and 1 novel, which together cost $19. Janelle goes to the same bookstore and buys 1 comic and 2 novels for $17. How much does each comic and each novel cost? adc
Each comic costs $4.71 and each novel costs $7.29.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b. where m is the slope and b is the y-intercept.
Let x be the cost of one comic and y be the cost of one novel.
From Amanda's purchase, we know that:
4x + y = $19
From Janelle's purchase, we know that:
x + 2y = $17
We can use the first equation to solve for y in terms of x:
y = $19 - 4x
We can substitute this expression for y into the second equation:
x + 2($19 - 4x) = $17
x + 2$19 - 8x = $17
-7x = $17 - 2$19
-7x = -$33
x = $33/-7 = $4.71
We can use this value of x to find the value of y:
y = $19 - 4($4.71) = $7.29
Hence, each comic costs $4.71 and each novel costs $7.29.

The graphs shows the speed of a car for 30 seconds. A) using a single appropriate trapezium , estimate the distance travelled by the car during this time . B) is your answer an overestimate or underestimate ?
The distance travelled by the car during this time by using single appropriate trapezium is 26.25 and the answer provided is an underestimate
Estimate the distance travelled by the car during this time?A) Using a single appropriate trapezium, the estimated distance travelled by the car during the 30 seconds is approximately 55 metres.
This is calculated by taking the area of the trapezium formed by the two points of the speed graph: 8m/s and 6m/s.
The area is calculated by taking the average of the two points, multiplied by the time duration:
Area = (8+6/2) * 30
Area = 7*30
Area = 210
The area of the trapezium is then divided by the speed of the car at the start of the journey (8m/s) to get the estimated distance travelled:
Distance = 210/8
Distance = 26.25
This is rounded up to give an estimated distance travelled of 55 metres.
B) The answer of 55 metres is an underestimate of the actual distance travelled by the car. This is because the trapezium method only takes into account the start and end points of the graph, and not any of the other points in between. The actual distance travelled by the car is likely to be higher as the speed of the car is likely to have been greater at points in between the start and end points.

Write & Solve a System of Equations to determine how many PUMPKIN pies they are selling.
Here is one possible system of equations to represent the information provided:
The system of equationsLet x be the number of apple pies, y be the number of pumpkin pies, and z be the number of key lime pies.
The number of apple pies is the same as the number of pumpkin and key lime pies combined, since both tables have the same number of pies: x = y + z
There are twice as many pumpkin pies as key lime pies: y = 2z
There are 5 more apple pies than pumpkin pies: x = y + 5
Solving for y in the second equation, we have: y = 2z
Substituting that into the first equation we have: x = 2z + z = 3z + 5
Substituting that into the third equation we have: x = y + 5 = 2z + 5
So we have a system of equations:
x = 3z + 5y = 2zNow we can solve for any of the variables. Let's find the number of PUMPKIN pies

Option B is correct.
What is area of square?The quantity of square units required to completely fill a square is known as the area of a square. The region that lies inside the confines of a flat item or a two-dimensional figure is generally referred to as the area. The measurement is made using square units, with square metres serving as the standard unit (m²).
Area of square = Side ²
side=6√2
Area=?
Area of square = ( 6√2)²
72 .0 inches.
Why square units for area?This is because the sum of two lengths is used to calculate an area. If those are, for instance, measured in meters, you would multiply some meters by others. Consequently, the expression for the area in square meters. Similar to volume: You divide three lengths by.

Graph y= 1/3x-3 .I just need to know the plots
Answer: Points: (0, -3), and (9, 0)
Step-by-step explanation:
In order to graph an equation, you find 2 pairs of points and then just connect them into a line. (The x intercepts and the y intercepts are helpful)
One pair: (x, y) = (0, -3)
Another pair: (x, y) = (9, 0)
Now just connect them to get the line :>
To the nearest hundredth find the value of x
Answer:
x = 14.83 (to the nearest hundredth)
Step-by-step explanation:
Following the Pythagoras' Theorem,
a² + b² = c²
x² + 6² = 16²
x² = 220
∴ x = 14.83 (to the nearest hundredth)
