Ethan, Chris and Jon have $90 altogether. Ethan has a half of that amount and Chris has one third of all the money. How much doe

stepladder [879]

The answer would be 15.

If Ethan has half of $90. You would have to divide $90 by 2, giving you $45.

And if Chris has a third of $90. You would have to divide $90 by 3, giving you $30.

Now, Chris. That leaves Chris with the rest of the money missing that adds up too $90. So if, $45 plus $30 equals $75. Subtract $75 from $90 which gives you $15 left.

Find the solutions to the equation below 30x^2-28x+6 =0

Naddik [55]

For this case, we have the following equation of the second degree:

$30x ^ 2-28x + 6 = 0$

If we divide between 2 on both sides of the equation, we will have:

$15x ^ 2-14x + 3 = 0$

Where:

$a = 15\\b = -14\\c = 3$

The solutions will come from:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}$

Substituting:

$x = \frac {- (- 14) \pm \sqrt {(- 14) ^ 2-4 (15) (3)}} {2 (15)}\\x = \frac {14 \pm \sqrt {196-180}} {30}\\x = \frac {14 \pm \sqrt {16}} {30}\\x = \frac {14 \pm4} {30}$
