Answer:

x= -1.73

Is 3.222222 a rational number
SIZIF [17.4K]

Answer:

<h2>YES</h2>

Step-by-step explanation:

If the number is rational, I can write it as a fraction in which the numerator and denominator are integers (denominator other than 0).

3.\underbrace{222222}_{6}=\dfrac{3222222}{1\underbrace{000000}_6}-\bold{RATIONAL}

If is repeating:

x=3.2222....       <em>multiply both sides by 10</em>

10x=32.2222...      <em>    make the difference 10x - x</em>

10x-x=32.2222...-3.2222...

9x=29             <em>divide both sides by 9</em>

x=\dfrac{29}{9}-\bold{RATIONAL}

Solve the equation for y. 8x – 9y = 11
Vikentia [17]
8x - 9y = 11    (subtract 8x from each side)

- 9y = -8x + 11  (divide -9 from each side)

\frac{-9y}{-9} = \frac{-8x+11}{-9}

y = \frac{-8}{-9} x - \frac{11}{9}

D. y=\frac{8}{9} x - \frac{11}{9}

Natasha2012 [34]

Answer:

John has 2 dollars and 46 cents left after his purchases.

Step-by-step explanation:

50 - 17.50 = 32.50

32.50 - 24.99 = 7.51

7.51 - 6.99 = 0.52

0.52 + 5.00 = 5.52

5.52 - 3.06 = 2.46
