Which of the following equations would be solved for x by adding 8 to both sides and then multiplying both sides by 2?
Answers
Answer: A
Step-by-step explanation:
The equation option 3rd is correct option.
What is an equation?An expression or a statement that comprises two algebraic expressions with the same value and are separated by an equal symbol in between them.
Given that, four equation,
5 = 3x/2 - 8
Adding 8 to both sides,
5 + 8 = 3x/2 - 8 + 8
13 = 3x/2
Multiplying by 2 to both sides,
13*2 = 3x/2*2
26 = 3x
x = 26/3
Hence, equation 3rd is the correct answer.

Read the excerpt from The Call of the Wild.
Then an old wolf, gaunt and battle-scarred, came forward. Buck writhed his lips into the preliminary of a snarl, but sniffed noses with him, Whereupon the old wolf sat down, pointed nose at the moon, and broke out the long wolf howl. The others sat down and howled. And now the call came to Buck in unmistakable accents. He, too, sat down and howled. This over, he came out of his angle and the pack crowded around him, sniffing in half-friendly, half-savage manner. The leaders lifted the yelp of the pack and sprang away into the woods. The wolves swung in behind, yelping in chorus. And Buck ran with them, side by side with the wild brother, yelping as he ran.
Which theme does this passage illustrate?
A good leader is strong and intelligent and treats his followers well.
Only the strong survive in the wilderness.
The only way to learn something is to try it.
The desire to fight for power is an instinct.
Answers

Answers
Answer:
The answer is 4 3/10
Step-by-step explanation:
If you first break this question up into two steps, you first must add the whole numbers and then the fractions, like this:
2 7/10 1 6/10
First, add the whole numbers [Bold]
2 + 1
That equals the whole number 3
2 7/10 1 6/10
Next you add the fractions [Underlined]
7/10 + 6/10
this equals 13/10
Since this fraction is higher than 10/10, it equals a whole number too. This fraction, 13/10, will be simplified to 1 whole and 3/10. After simplifying this number you add the whole numbers once again resulting in 3 + 1, giving you 4. after finding this out you add your fractions back in, creating the answer of 4 3/10.

The rabbit population in a certain area is 200% of last year's population. There are 300 rabbits this year. How many were there last year?
Answers
Answer:
There were 650 rabbits last year
The percentage of a quantity can be found by first changing the percent into a fraction and then multiplying it to the value of that quantity. Last year the number of rabbits was 150.
What is percentage?A percentage is a value that indicates the hundredth part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The population of rabbit this year is 300.
The percentage of the population with respect to the last year is 200%.
Suppose the population of rabbits last year was P.
Then as per the question, following expression can be written,
200% of N = 300
⇒ (200 / 100) × N = 300
⇒ 2N = 300
⇒ N = 150
Hence, the population of the rabbits last year was 150.

An airline tracks data on its flight arrivals. Over the past six months, 65 flights on one route arrived early, 273 arrived on time, 218 were late, and 44 were cancelled. What is the probability that a flight is early
Answers
Answer:
0.108
Step-by-step explanation:
Given that:
Number of flights reached early = 65
Number of flights reached on time = 273
Number of flights reached late = 218
Number of flights canceled = 44
To find:
The probability that a flight is early.
Solution:
First of all, let us have a look at the formula for probability of an event E.
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, Event E is that the flight is early.
Number of favorable cases is equal to the number of a flights which reached early i.e. 65
Total number of cases is the total number of flights.
i.e. 65 + 273 + 218 + 44 = 600
So, the required probability is:
[tex]P(E) = \dfrac{65}{600} = \bold{0.108}[/tex]

Answers
Answer:
The midpoint (x,y)=(6,9)
Step-by-step explanation:
We need to find midpoints(x,y) of the line segment having endpoints S(8, 8) and T(4, 10)
The formula to find midpoint is:
[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\[/tex]
We are given: [tex]x_1=8, y_1=8, x_2=4 , y_2=10[/tex]
Putting values and finding midpoint
[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint(x,y)=(\frac{8+4}{2},\frac{8+10}{2})\\Midpoint(x,y)=(\frac{12}{2},\frac{18}{2})\\Midpoint(x,y)=(6,9)[/tex]
So, the midpoint (x,y)=(6,9)

Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)
Step-by-step explanation:
Solve for x:
F x = 2 x^2 - 4 x + 1
Subtract 2 x^2 - 4 x + 1 from both sides:
-2 x^2 + F x + 4 x - 1 = 0
Collect in terms of x:
-1 + x (F + 4) - 2 x^2 = 0
Divide both sides by -2:
1/2 + 1/2 x (-F - 4) + x^2 = 0
Subtract 1/2 from both sides:
1/2 x (-F - 4) + x^2 = -1/2
Add 1/16 (-F - 4)^2 to both sides:
1/16 (-F - 4)^2 + 1/2 x (-F - 4) + x^2 = 1/16 (-F - 4)^2 - 1/2
Write the left hand side as a square:
(1/4 (-F - 4) + x)^2 = 1/16 (-F - 4)^2 - 1/2
Take the square root of both sides:
1/4 (-F - 4) + x = √(1/16 (-F - 4)^2 - 1/2) or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)

Answers
Answer:
5x-5+3x+3+5x=180
Step-by-step explanation:
As it is a triangle, sum of all angles is 180.
5x-5+3x+3+5x=180
13x=182, x=14
The expression that represents the measure sum of the angle is
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that sum of all the interior angles of a triangle is 180°.
The given statement can be written as,
∠A + ∠B + ∠C = 180°.
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
13x - 2° = 180°.
13x = 180° + 2°.
13x = 182°.
x = 14°.
We can also find the measure of each angle now by substituting the value of x in ∠A, ∠B, and ∠C.
