Answer:
25
Step-by-step explanation:
- - 6/5x = -30 ⇒ multiply both sides by -1
- 6/5x = 30 ⇒ multiply both sides by 5
- 6x = 5*30
- x = 150/6 ⇒ divide both sides by 6
- x = 25 ⇒ answer
<span>So the question is what is 8/32 in the simplest form. To find out we need to simplify the fraction. In this case the nominator and the denominator are both multiple of 8 so the nominator is 8=1*8 and 32=4*8 so we can write (1*8)/(4*8) and we see that we can cancel out number 8 and get 1/4 which is the simplest form of the fraction. </span>

Answer:
17,28 %
Step-by-step explanation:
81 .............. 100%
14 ....................x%
x = 14×100/81 = 1400/81 ≈ 17,28 %
First multiply all terms by z
8-z^2=4z
Then order into standard form
-z^2-4z+8=0
Multiply the equation by -1
z^2+4z-8=0
Plug into quadratic equation
-4±√16-4(-8)
-4±√48
(-4±4√3)/2
-2±2√3
Final answer: z=-2± 2√3
