Awnser-H=5/2
Explantion- Absolute value equalitiy entered
7|-3h+8| = 21h-49 Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 7|-3h+8|
For the Negative case we'll use -7(-3h+8)
For the Positive case we'll use 7(-3h+8)
-7(-3h+8) = 21h-49
Multiply
21h-56 = 21h-49
Rearrange and Add up
0h = 7
False, No solution for the Negative Case 7(-3h+8) = 21h-49
Multiply
-21h+56 = 21h-49
Rearrange and Add up
-42h = -105
Divide both sides by 42
-h = -(5/2)
Multiply both sides by (-1)
h = (5/2)
Which is the solution for the Positive Case When an absolute value equation has just one solution, that solution has to be checked:
The equality is 7|-3h+8| = 21h-49
The solution is h = 5/2
We check the solution by plugging it for h
7|-3(5/2)+8| = 21(5/2)-49
The left hand side is equal to (7/2)
The right hand side is equal to (7/2)
The two sides are equal!
Solution checks!
h=5/2

Answer:
52
Step-by-step explanation:
Angle A equals 4x+8
Angle B equals 5x-b
and they are vertical angles.
If so, vertical angels are equal. You can set the expressions equal to each other, solve for x, and plug that value back in to solve for A.
4x+8=5x-b
add 3 to both sides
4x+11=5x
subtract 4x from both sides
11=x
Then plug x=11 into 4x+8.
4(11)+8
44+8

27⅛ ÷ 3½
in my opinion, turning it into a decimal is easier
27 ⅛ = 27.125
3 ½ = 3.5
so.....
27.125 ÷ 3.5 = 7.75 which is also 7 ¾
