How do you rewrite 3.83 repeating as a simplified fraction

babymother [125]

If the number is 3.8333333.... then

X=3.83333....
10X = 38.3333.....

10X - X
38.3333....
- 3.8333....
= 34.5
so 9X = 34.5
X = 34.5/9
Multiple both top and bottom by 2 to get rid of decimal.
69/18
Normalize it to get rid of improper fraction.
3 15/18
Simplify
3 5/6

If the number is 3.838383838383.... then
X = 3.83838383...
100X = 383.83838383...

100X - X = 99X
383.83838383...
3.83838383...
380

99X = 380
X = 380/99

X = 3 83/99

$\text{Mixed number:}\ 6\dfrac{5}{6}\\\\\text{Improper fraction:}\ 6\dfrac{5}{6}=6+\dfrac{5}{6}=\dfrac{6\cdot6}{6}+\dfrac{5}{6}=\dfrac{36}{6}+\dfrac{5}{6}=\dfrac{41}{6}$

If x=3 is a solution of the equation 2x²-5x+k=0 find the value of k

Novosadov [1.4K]

Answer:

k = - 3

Step-by-step explanation:

Given that x = 3 is a solution then it satisfies the equation, that is

2(3)² - 5(3) + k = 0

2(9) - 15 + k = 0

18 - 15 + k = 0

3 + k = 0 ( subtract 3 from both sides )

k = - 3
