Answer:

2(x + 6) = 38

Step-by-step explanation:

First, we choose a variable to represent the unknown number.

1. Let x = the unknown number.

Then, we translate the sentence into an equation using the variable we chose.

"Twice the sum of six and a number is 38."

We do it piece by piece:

"the sum of six and a number":                        x + 6

"Twice the sum of six and a number":              2(x + 6)

"Twice the sum of six and a number is 38.":    2(x + 6) = 38

Now we have an equation that represents the sentence.

2(x + 6) = 38

Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.

2) Use the word "to" : a to b

3) Write it in fraction: a / b

What is Irrational Number?

An Irrational number is areal number that cannot be expressed as a ratio of integers; for example [tex]\sqrt{2}[/tex] is an irrational number. We cannot express any irrational number in the form of ratio, such as p/q, where p and q are integers, q[tex]\neq[/tex] 0. Again, the decimal expansion of an irrational number in neither terminating nor recurring.

Let us assume [tex]7\sqrt{56}[/tex] is rational.

So, we can write this number as

[tex]7\sqrt{56}[/tex] = a/b __(1)

Here, a and b are two co-prime numbers and b is not equal to zero.

Simplify the equation (1) divide by 7 both sides, we get

[tex]\sqrt{56}=\frac{a}{7b}[/tex]

Here, a and b are integers, so a/7b is a rational number, so [tex]\sqrt{56}[/tex] should be a rational number.

But [tex]\sqrt{56}[/tex] is a irrational number, so it is Contradictory.

Therefore, [tex]7\sqrt{56}[/tex] is irrational number.

Given,

Four friends are sitting at a table together at the prom.

Here we need to find  the probability that a particular one of them will sit in the chair closest to the dance floor.

Since the samples are arranged with a fixed reference point, this is a linear permutation.

So there are 4! or 24 ways in which the samples can be arranged.

The number of favorable outcomes is the number of permutations of the other 3 people given that a particular one of them will sit in the chair closest to the dance floor, 3! or 6.

Given events are independent events and the probability that getting an even number on die and getting odd number on a spinner numbered 1 to 5

In this question,

we have been given two events.

Let event A: rolling an even number on a die

event B: spin a spinner numbered 1 through 5 and get an odd number.

We can clearly observe that the occurrence of event A is not dependent on the other event B.

So, event A and event B are independent events.

The probability of event A is,

P(A) = n(A) / n(S)

here, sample space, n(S) = 6

n(A) = 3

So, P(A) = 3/6

P(A) = 1/2

The probability of event B is,

P(B) = n(B) / n(S)

here, sample space, n(S) = 5

n(B) = 3

So, P(B) = 3/5

Now we find the joint probability of these independent events.

⇒ P = P(A) × P(B)

⇒ P = 1/2 × 3/5

⇒ P = 3/10

Therefore, given events are independent events and the probability that getting an even number on die and getting odd number on a spinner numbered 1 to 5

a(n) = a r^(n-1)

Where:

Using Substitution method,

From the equation (1) i.e., x - 2y = 4 , the value of x is

Answer:

B.  -2  <  x  <  4

Step-by-step explanation:

The function is (x +2)/(x-4) and we are asked to determine the x interval when the inequality (x +2)/(x-4) < 0 is satisfied

1. Find the critical points

The critical points are

x = - 2 when the numerator becomes -2 + 2 = 0, and f(x) = 0

and

x = 4 when the denominator becomes 4 - 4 = 0 and (x + 2)/0 is undefined

So critical points are -2 and 4

2. Use these critical points to divide the number line into intervals
The intervals are -∞ < x < -2, -2 < x < 4 and 4 < x < ∞
these can be re-written as x < -2, -2 < x < -4 and x > 4

3. For each  of these intervals take a test point and see if it satisfies that inequality
(a) -∞ < x < -2    Take x = -3 which is less than -2
We get f(-3) =  (-3 + 2)/(-3 -4) = -1/-7 which is + 1/7 and does not satisfy the (x+2)/(x-4) < 0 inequality.

So we can discard this interval
(b) For interval -2 < x < 4, Let's take x = 0
(0+2)/(0-4) = 2/(-4) = -1/2 = -0.5 which does satisfy the inequality
(x+2)/(x-4) <0, so this is a valid interval

(c) For interval x > 4, take x = 5
(x+2)/(x-4 ) = (5 + 2)/(5-4) = 7/1 = 7 and does not satisfy (x+2)/(x-4 ) < 0

So the interval which satisfies the inequality is -2 < x < 4
