Sum of all angles in a triangle = 180°
Which means :-
∠1 + ∠2 + ∠3 = 180°
[tex]2x + x + x + 8 = 180°[/tex]
[tex]4x + 8 = 180°[/tex]
[tex]4x = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]x = \frac{172}{4} [/tex]
[tex]x = 43[/tex]
Angle 1 :-
= 2x
= 2 × 43
= 86°Angle 2 :-
= x
= 43°Angle 3 :-
= x + 8
= 43 + 8
= 51°[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

are added to the pile. How many eggs are
there in the pile?
Given parameters:
Number of eggs in a pile on the desk = 62 eggs
Eggs per package = 6
Number of added eggs = 6
Unknown:
Number of eggs in the pile = ?
Solution:
To find the number of eggs in the pile, simply add the original amount of eggs to that which was added;
Number of eggs in pile = (62 + 6)eggs = 68 eggs
Number of eggs there in the pile are 68 eggs

What is different about the solutions to an inequality (like r > -3) with that of an equation (like
= 2)?
When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.
Hope this helps.
what is 6.08 rounded to the nearest tenth
Answer:
6.1
Step-by-step explanation:
anything 5 and over you round to one, so .08 turns into .1 :) glad i could help
The given decimal number is rounded to the nearest tenth as 6.1.
The given decimal number is 6.08.
Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
Here, in 6.08 digit in the hundredths place is 8, which is greater than 5.
So, the digit in the tens place increased by 1 and digits after tens place becomes zero.
That is, 6.10
Therefore, the given decimal number is rounded to the nearest tenth as 6.1.

A.) 1,400-2,000
B.) 0-3,500
C.) 1,600-1,800
D.) 1,500-1,900
Your answer is:
A) 1,400 - 2,000
keep believing and dont give up.
if nobody loves you, i do
Option A is right.
Given that:
Mean = 1700
Standard deviation = 100
So, the range for 3 standard deviations to the right and to the left of the mean is:
[tex]\left(1700-3\left(100\right)\ ,\ 1700\ +\ 3\left(100\right)\right)\\=\left(1700-300,\ 1700\ +\ 300\right)\\=\left(1400,\ 2000\right)[/tex]

Jason solved the following equation to find the value for x.
–8.5x – 3.5x = –78
x = 6.5
Describe how Jason can check his answer.
Sample answer:
Substitute the value for x into the original equation. Simplify using order of operations. If the statement is true, Jason’s solution for x is correct. If the statement is false, Jason’s solution for x is incorrect.Step-by-step explanation: (My answer)
1) Subtract 8.5 and 3.5, that equals 12.
[tex]8.5x - 3.5x = -78[/tex]
2) Multiply 78 and 12, that equals 6.5 .
[tex]\frac{12x}{12} = \frac{78}{12}[/tex]
3) Check your answer.
[tex]-8.5 (6.5) -3.5 (6.5) = -78[/tex]
Multiply 8.5 and 6.5, that equals 55.25. Next, multiply 3.5 and 6.5, that equals 22.75.Finally, you will need to subtract your answers. Subtract both 55.25 and 22.75.Once you've done that, the answer you should get is 78.
78 is equal to 78, that is your final answer and it is correct.

Which graph represents f(x) = 1/2x^5
The solution is option a)
How to graph an equation?
To graph an equation using the slope and y-intercept. Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). Next, plot the y-intercept. From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.
Given data ,
Let the function be f ( x ) = ( 1 / 2 ) x⁵
Now , to know which graph represents the equation mentioned, you can put some values of x in the equation and evaluate the value of y
So , when x = 1
y = ( 1 / 2 )
when x = 2
y = ( 1 / 2 ) × 2⁵
= 2⁴
= 16
when x = -1
y= ( 1 / 2 ) × ( -1 )⁵
= - ( 1 / 2 )
So , by plotting all the points of x and y in the graph , Option a ) satisfies the solution
Hence , the solution is Option a)

An electronics superstore normally sells a new smartphone for $200, but it is currently offering a 50% discount off the price. The same phone is available online for $200; the website is offering 25% off the phone, plus another 25% discount off all purchases. Where should you buy the phone to get the better deal? Why?
Answer: They are equal, but if you are buying something else with it,, say a case, the website
Step-by-step explanation:
Website:
1/4 +1/4 = 1/2
Store:
1/2
Answer:
the 50% off is the better deal
Step-by-step explanation:
200 x .50= 100 so on the first phone you save $100
the website you get 25% off so .25 x 200=50 so 200 - 50 =150 then you get another 25% off .25 x 150 =37.50 so 150 - 37.50 = 112.50.
