The required numbers are [tex]2\frac{2}{5}[/tex] and [tex]2\frac{5}{8}[/tex] .
In this question , given is [tex]2\frac{2}{5}[/tex] , [tex]2\frac{2}{7}[/tex] , [tex]1\frac{7}{8}[/tex] , [tex]2\frac{1}{10}[/tex] , [tex]2\frac{5}{8}[/tex]
So when we solve it we get; [tex]\frac{12}{5} , \frac{16}{7} , \frac{15}{8} , \frac{21}{10} , \frac{21}{8}[/tex]
We need two numbers whose sum should be greater than 5
first adding the numbers which have the same denominator we get:
[tex]\frac{15}{8} + \frac{21}{8}[/tex]
[tex]\frac{36}{8}[/tex]
which on dividing will give us 4.5 < 5
Lets take numbers [tex]\frac{12}{5} , \frac{16}{7}[/tex]
On taking LCM we get ;
[tex]\frac{84+ 80}{35}[/tex] = [tex]\frac{164}{35}[/tex] = 4.6 < 5
Lets now take [tex]\frac{16}{7} + \frac{15}{8}[/tex] = [tex]\frac{128+ 105 }{56}[/tex] = [tex]\frac{233}{56}[/tex] = 4.16 < 5
Lets take [tex]\frac{12}{5} + \frac{21}{8}[/tex] = [tex]\frac{96+ 105}{40}[/tex] = 5.025 > 5
Thus the required numbers are : [tex]\frac{12}{5} and \frac{21}{8}[/tex].
So in these type of questions we are supposed to take two or the numbers which have been given in the question and then we should add or subtract them as per the question .
Likewise in this question we had to find two numbers and after so many trials we were able to get the two required numbers.

Find the sum: 4-2(x-3)=24
The first step to find the value of 'x' in this expression is to calculate the product with the parenthesis term:
[tex]\begin{gathered} 4-2(x-3)=24 \\ 4-2x+6=24 \end{gathered}[/tex]Then, we need to isolate in one side of the equation the terms with the variable 'x', and in the other side the terms without the variable 'x'. Then, we can calculate the value of x:
[tex]\begin{gathered} 4-2x+6=24 \\ -2x=24-4-6 \\ -2x=14 \\ x=\frac{14}{-2}=-7 \end{gathered}[/tex]So the value of x in this expression is -7
A monkey can eat 24 pieces of fruit in 12 hours.
The equation y = 2x can be used to represent
this situation. What is the constant of
proportionality? What does the constant of
proportionality represent in the context of the
problem?
The constant of proportionality for the equation y = 2x is k = 2.
The number of pieces of fruit the monkey can eat is two times the amount of time the monkey takes.
The equation y = 2x can be used to represent a monkey eating 24 pieces of fruit in 12 hours.
The constant of proportionality, which is a fixed value that represents the rate at which two or more ratios rise or decrease, is used to compare them. The result of dividing the denominator by the numerator when a ratio is expressed as a fraction is the constant of proportionality.
When a ratio is expressed as a fraction, the constant of proportionality is found by dividing the denominator by the numerator. The constant of proportionality, k, can be calculated from the equation if x is the ratio's numerator and y is its denominator.
k = y/x
Therefore, the constant of proportionality in this case is:
y = 2x
k = y/x = 2
The constant of proportionality in this case represents that the number of pieces of fruit a monkey eats is two times the amount of time the monkey takes.

The non-real solutions of the polynomial expression are x = (2 + i√26)/3 and x = (2 - i√26)/3
How to determine the non-real solutions?The equation of the polynomial expression is given as:
3x^3 + 14x^2 - 14x + 60 = 0
From the question, we have
Real solution = -6
Rewrite the above equation as
x = -6
Add 6 to both sides of the equation
So, we have
x + 6 = 0
The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0
This is represented as
3x^3 + 14x^2 - 14x + 60/x + 6
Using a graphing calculator, we have
3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10
Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula
So, we have
x = (-b ± √(b² - 4ac))/2a
This gives
x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3
So, we have
x = (4 ± √-104)/6
This gives
x = (4 ± 2√-26)/6
Divide
x = (2 ± √-26)/3
Rewrite as
x = (2 ± i√26)/3
Split
x = (2 + i√26)/3 and x = (2 - i√26)/3
So, the conclusion is that
Using the polynomial expression, the non-real solutions are x = (2 + i√26)/3 and x = (2 - i√26)/3

The mapping diagram above does not represent a function since

from Set B (the output).
What is a function?In Mathematics, a function simply refers to a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.
This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (Set A) to an output variable (Set B).
Based on the mapping diagram shown above, we can reasonably infer and logically deduce that Set A with inputs (-4, 8), (1, 8) and (1, -3) are ordered pairs which does not represent a function because they indicate multiple mappings in Set B (the output).

The elements in the set A'∩B is { z } .
Set theory is a branch of mathematical logic that studies sets, which are essentially collections of objects.
Despite the fact that any type of object can be assembled into a set, set theory is a branch of mathematics that primarily deals with issues that are relevant to mathematics as a whole.A straightforward binary link between an object o and a set A serves as the basis of set theory. If o is a component (or member) of A, it is expressed as o A. When describing a set, members are listed with commas to indicate separation, or a property of those components is contained in braces. Since sets are objects, they can be related by the membership relation.Given universal set U = {q, r, s, t, u, v, w, x, y, z}
set A = {q, s, u, w, y}
∴A' = {r, t, v, x, z}
set B = {q, s, y, z}
Now A'∩B = { z }
Hence the elements in the set A'∩B is { z } .

A Shopper has $140 to spend. The shopper wants to buy shirts and hats. Each shirts coats $21, and each hat cost $16. What combination of shirts and hats maximizes the amount of money the shopper can spend
The combination of two shirts and six hats will maximize the amount of money the shopper can spend.
What are Mathematical Inequalities?An inequality results from the comparison of two or more algebraic expressions using the symbols <, > ≤, or ≥. They are mathematical expressions with unequal sides.
Let's assume x is the number of shirts and y is the number of hats brought then,
Total amount spend = 21x + 16y
It is given that the total amount the shopper can spend is $140.
So, 21x + 16y ≤ 140,
As x and y are the number of shirts and the number of hats so x and y will assume positive integral values only, to find out the values of x and y plot the region 21x + 16y ≤ 140 with x ≥ 0, y ≥ 0 as shown in the graph.
From the graph, it is clear that the highest integer value which is close to the boundary of 21x + 16y ≤ 140 is x = 2 and y = 6.
The amount spend when x = 2 and y = 6 is 21(2) + 16(6) = 138
Hence, two shirts and six hats will maximize the amount of money the shopper can spend.
