What is additive comparison?

In an additive comparison, we question or state how much more (or less) one amount is in contrast to the other to determine the relationship between the two numbers. Additive comparison issues are typically word problems that can be resolved by creating an equation.

The comparison approach is a technique for rewriting each equation with the same variable as the subject in order to solve systems of independent equations. The initial variable to isolate can be any of the variables. Every equation is now an isolated-subject equation with an isolated variable.

Let,

  if in about x month, the population of the towns will be equal .

the equation will be;

                          70,000 + (150-100)x = 61,000 - 200x

                        ⇒  70,000 + 50x = 61,000 - 200x

                        ⇒ 250x = 9000

                       ⇒ x = 9000/250

                      ⇒ x = 36

So, in 36 months the populations of the 2 cities be the same .

The required measure of the angles x and y is given as 50°.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,

As it can be seen, x and y are alternate-opposite equal angles,
x = y

Now,
Adding complementary angles to 180°,
x + 60 + 70 = 180
x = 180 - 130
x = 50°

So,
x = y = 50°

Thus, the required measure of the angles x and y is given as 50°.

Answer: When we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function f(x)=5−3x2 f ( x ) = 5 − 3 x 2 can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5.

Step-by-step explanation:

Functions is an important branch of math, which connects the variable x with the variable y. Functions are generally represented as y = f(x) and it states the dependence of y on x, or we say that y is a function of x.

Eliud was running 125 miles per week, and now he is running 20% more. To determine how many miles Eliud is now running per week, the equation is 125 plus 125 times 0.2, which equals 150 miles per week.

125 + (125 x 0.2)

=125 + 25

= 150

Eliud was previously running 125 miles per week. To determine how many miles he is now running per week, an equation needs to be solved. The equation is 125 plus 125 times 0.2, which equals 150 miles per week. This is because 20% of 125 is 25, so 125 plus 25 is 150. Therefore, Eliud is now running 150 miles per week, which is an increase of 25 miles per week from his previous running amount. This increase of 25 miles per week is equivalent to 20% more than he was previously running. Solving this equation reveals that Eliud is now running 150 miles per week, which is an increase of 20% from his previous mileage.

The sum of the interior angles of a 21-gon (21 sides) is 3420°.

What are Interior angles?

Any angle that is created between two of a polygon's adjacent sides is said to be its internal angle. The internal angle of a polygon is what we might refer to as the angle measured at the interior portion of a polygon.

The polygon has 21 sides.

we can find the sum of all interior angles of the polygon by using this formula :

S = 180 ( n - 2)

So, S = 180 (21 - 2)

If the product is positive integers is 32118, then the king's age is 53, his number of children is 6 and is length of boat is 101m.

What is integer?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

The puzzle demands for three numbers - x, y, z which represent the king's number of children, age and length of boat respectively.

It will be advantageous to conceive the problem thus: We have but one unknown; this unknown, however, is not a number but a tripartite unknown, a triplet (x, y, z) of numbers.

It is very important to split the condition that is expressed by the statement of the problem into appropriate clauses. This needs careful con-sideration of details and considerable regrouping. After several trials (which we skip to save space) we may arrive at the following two clauses:

(r1), x, y, and z are positive integers different from 1 and such that -

xyz = 32118

(r2) 4 ≤ x < y < 100

Begin with (r1) which leaves only a finite number of possibilities, whereas (r2), which does not restrict z at all, leaves an infinite number.

Therefore, we examine (r1). Now, 32118 is divisible by 6, and so we easily decompose it into prime factors:

32118 = 2 × 3 × 53 × 101

For a decomposition into three factors we have to combine two of the four primes. Therefore, there are only six different ways to decompose the number 32118 into a product of three factors all different from 1:

6 × 53 × 101

3 × 101 × 106

3 × 53 × 202

2 × 101 × 159

2 × 53 × 303

2 × 3 × 5353

Of these six possibilities, the remaining requirement (r2) rejects all except the first one, and so we obtain -

x = 6 , y = 53 and z = 101.

Therefore, the values of x, y and z are 6, 53 and 101 respectively.

The domain of function, (cd)(x) is all real values of x except x = 2, i.e., (−∞,2)∪(2,∞).

The domain of a function is defined as a set of values accepted by function. In this case, we have a rational function. A rational function will only be defined if the denominator is not equal to zero. We have, two functions, c(x) = 5/ x - 2 and

d(x) = x + 3. We should determine the domain of (cd) (x). The product of two is (cd) (x) = c(x) . d(x)

=> (cd)(x) = (5/(x - 2) )(x + 3) = 5(x+3)/(x -2)

Which is a rational function. So, the function will be defined if the denominator is not equal to zero, i.e., x - 2 ≠ 0 => x ≠ 2. Thus, domain set of function contains all real numbers values except 2. Therefore, the required domain of function (cd) (x) is all real values of x except 2.

Satisfying all the given situations, there were 156 candidates in the examination.

We can use the principle of inclusion-exclusion to solve the problem.

The principle of inclusion-exclusion states that the total number of elements in the union of two or more sets is equal to the sum of the number of elements in each set, minus the number of elements in their intersection.

Here, let A be the set of candidates who offered biology, B be the set of candidates who offered history, and C be the set of candidates who offered mathematics.

Using the principle of inclusion-exclusion, the total number of candidates, N, can be found as follows:

N = (A U B U C) = (A + B + C) - (A ∩ B + B ∩ C + A ∩ C) + (A ∩ B ∩ C)

where A U B U C is the union of the three sets, A ∩ B is the intersection of A and B, and so on.

Given that:

|A| = 52, |B| = 60, |C| = 96

|A ∩ B| = 21, |A ∩ C| = 22, |B ∩ C| = 16

|A ∩ B ∩ C| = 7

Therefore,

N = (52 + 60 + 96) - (21 + 22 + 16) + 7

N = 156

The value of x = 3 and y = 1 is the solution.

Two or more algebraic equations that have a common variable and are solved simultaneously are referred to as simultaneous equations (that is, simultaneously). For instance, the simultaneous equations x + y = 5 and x - y = 6 are created by concurrently solving two equations that have the same unknown variables, x and y. Multiple techniques, including the substitution method, elimination approach, and visual methods, can be used to solve simultaneous equations.

We have 2 equations,

2x - y = 5 (equation 1)

3x + 2y = 11 (equation 2)

We can solve the given equations simultaneosuly.

Multiplying equation 1 by 2,

4x - 2y = 10

Adding the 2 equations,

4x - 2y = 10

3x + 2y = 11

⇒ 7x = 21

⇒x = 3

Substituting the value of x = 3 in equation 1,

2x - y = 5

⇒ 6 - y = 5

⇒ y = 1

Hence, the values of x and y are 3 and 1 respectively; this is the solution of the equation.
