The solution to the equation 3 / 5x-2 = 2 / 3x-1 is x = 1.
What is the solution to the given equation?Given the equation in the question;
3 / 5x-2 = 2 / 3x-1
To solve for x, cross multiply the equation
3 / 5x-2 = 2 / 3x-1
3( 3x - 1 ) = 2( 5x - 2 )
Apply distributive property
3( 3x - 1 ) = 2( 5x - 2 )
3×3x + 3×-1 = 2×5x + 2×-2
9x - 3 = 10x - 4
Subtract 10x from both sides
9x - 10x - 3 = 10x - 10x - 4
9x - 10x - 3 = - 4
Add 3 to both sides
9x - 10x - 3 + 3 = - 4 + 3
9x - 10x = - 4 + 3
-x = -1
Divide both sides by -1
-x/-1 = -1/-1
x = 1
Therefore, the value of x is 1.

The set {10,17,27} does not represent the three sides of a triangle,
What are triangles?Having three edges and three vertices, a triangle is a three-sided polygon. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
Given the sets for the triangles,
property of triangles says that,
The length of a triangle's two longest sides added together is longer than the third side.
Similarly to this, the length of the third side of a triangle third side is shorter than the difference between its two sides.
1: given sides are 10, 17, 27
according to the property sum of 10 and 17 should be greater than 27 but sum is equal to 27,
10 + 17 = 27,
so the sides do not represent the triangle
2: sides are 9, 22, 30
here 9 + 22 > 30
the set represents the triangle.
3: sides 6, 16, 19
6 + 16 > 19
the set represents the triangle.
4: sides 4, 7, 9
4 + 7 > 9

The perimeter of a rectangular red sticker is 14 millimeters. The sticker is 4 millimeters wide. How tall is it?
Answer:
3 millimeters
Step-by-step explanation:
The formula for finding perimeter: 2W+2L=P
W= width
L= length
P= Permiter
So just substitute the numbers in the equation
4 millimeters is the width
14 millimeters is the perimeter
So this is your equation
2*4+2L=14
8+2L=14
Subtract 8 from both sides
2L=6
Divide both sides by 2
L=3
So your length is 3 millimeters
To check:
(2*4)+(2*3)=14
8+6=14
14=14

Use =6 for the year 2006, =7 for the year 2007, etc. ()= { −3.692 +65.28+437.30 6≤ <12 −10.17+691 ≥12 a. According to (), how many Barnes & Noble stores were there in 2009?
The required number of Barnes & Noble stores in 2009 is 725.28.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
To determine the number of Barnes & Noble stores in 2009, we need to evaluate the piecewise function for t = 2009.
Since 2009 is between the interval 6 ≤ t < 12, the number of stores is given by the first piece of the function:
y = -3.692 × x² + 65.28 × x + 437.30
put x = 9 for the year 2009
y = -3.692 × 9² + 65.28 × 9 + 437.30 = 725.28
So, there were 725.28 Barnes & Noble stores in 2009.

c) Shahina has 550 g of apples and plenty of the other ingredients.
Can she make apple crumble for 6 people? Yes/No
Explain how you got your answer.
Show your working
|+
Answer: a) To make apple crumble for 16 people, Farid will need to double the ingredients as compared to serving 8 people. Hence, he will need:
700g * 2 = 1400g of apples
240g * 2 = 480g of sugar
180g * 2 = 360g of flour
So, Farid needs 360g of flour to make apple crumble for 16 people.
b) To make apple crumble for 2 people, Amal will need to use 1/8 of the ingredients as compared to serving 8 people. Hence, she will need:
700g / 8 = 87.5g of apples
240g / 8 = 30g of sugar
So, Amal needs 30g of sugar to make apple crumble for 2 people.
c) To make apple crumble for 6 people, Shahina will need to adjust the ingredients based on the apples she has available. To calculate the amount of sugar and flour required, she can use the ratio of sugar and flour to apples as follows:
Sugar: 700g / 8 = 87.5g per serving * 6 people = 525g
Flour: 700g / 8 = 87.5g per serving * 6 people = 525g
Since Shahina has plenty of the other ingredients, including butter, she can make apple crumble for 6 people with the amount of apples she has available. So, the answer is Yes, Shahina can make apple crumble for 6 people.

Differentiation is a technique for determining a function's derivative. Differentiation is a mathematical procedure that determines the instantaneous rate of change of a function based on one of its variables. The process of finding the derivative of dependent variable in an implicit function by differentiating each term separately
Given data ,
Let the function be represented as f ( x )
Substituting the values in the equation , we get
f ( x ) = √ ( 5 - x² )
Now , the derivative of the function is f' ( x )

3x + 5 = x - 2 ( subtract x from both sides )
2x + 5 = - 2 ( subtract 5 from both sides )
2x = - 7 ( divide both sides by 2 )
x = - 3.5
substitute x = - 3.5 into either of the 2 equations for y

In which:
The slope m represents the rate of change.The intercept b represents the initial value.Two points for the function are given as follows:
(5, 55000) and (8, 61600).
Dividing the change in the output by the change in the input, the slope m is given as follows:
m = (61600 - 55000)/(8 - 5)
m = 2200.
Hence:
P(t) = 2200t + b.
When x = 5, y = 55000, hence the intercept b is given as follows:
55000 = 2200(5) + b
b = 55000 - 2200(5)
b = 44000.
Hence the function is:
P(t) = 2200t + 44000.
2010 is 10 years after 2000, hence the estimate is given as follows:
