What is the solution set for StartAbsoluteValue 4 minus StartFraction x over 2 EndFraction EndAbsoluteValue = 8?
A.x = negative 24 and x = negative 8
B.x = negative 24 and x = 24
C.x = negative 8 and x = 8
D.x = negative 8 and x = 24
The solution to the set is .x = negative 8 and x = 24.
What is Absolute value?The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.
Given:
|4 - x/2| = 8
So, there are two possibilities
4- x/2 = 8 or 4 - x/2 = -8
-x/2 = 8-4 or -x/2 = -8-4
-x/2 = 4 or -x/2 = -12
x= -8 or x= 24
Hence, the solution to the set is .x = negative 8 and x = 24

18.1
17.3
15.9
16.4
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
[tex]a^{2} +b^{2}= c^{2}[/tex]
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
[tex]10^2+b^{2} =20^{2}[/tex]
Then, use the squares in the equation:
[tex]100+b^{2} =400[/tex]
Then, subtract 100 from both sides to isolate b:
[tex]b^{2} =300[/tex]
Finally, square root both sides to get your answer:
[tex]b=17.3205080757[/tex]
Then round to the nearest tenth which gives you 17.3.

Answer:
x = 20
Step-by-step explanation:
If angle PQS is = 70° then

5x - 30 = 70 add 30 to both sides
5x = 100 divide both sides by 5
x = 20

Answer:
x = 8
Step-by-step explanation:
Corresponding segments are proportional.
(3x +1)/10 = (7x -1)/22
11(3x +1) = 5(7x -1) . . . . . . multiply by 110
33x + 11 = 35x -5 . . . . . . eliminate parentheses
16 = 2x . . . . . . . . . . . add 5-33x to both sides
8 = x . . . . . . . . . . divide by 2
Answer:
Solution :-[tex] \sf \bull \large \: \dfrac{3x + 1}{10} = \dfrac{7x - 1}{22} [/tex]
