Kenneth has entered a check payment of $350.25 in his checkbook. If the old balance was $545.95, what is his latest balance? A.)$896.25
B.)$195.70
C.)$195

Answers

Answer:

The correct option is B.

Step-by-step explanation:

The old balance of kenneth's checkbook was $545.95.

Kenneth has entered a check payment of $350.25 in his checkbook.

It means the balance of checkbook is reduced by $350.25.

The latest balance of check book is

$\$545.95-\$350.25=\$195.70$

Therefore the latest balance of kenneth's check book is $195.70. Option B is correct.

$(3x+1)(2x-5)=39 \n6x^2-15x+2x-5=39 \n6x^2-13x-5=39 \ \ \ \ \ \ \ \ \ \ |-39 \n6x^2-13x-44=0 \n6x^2-24x+11x-44=0 \n6x(x-4)+11(x-4)=0 \n(6x+11)(x-4)=0 \n6x+11=0 \ \lor \ x-4=0 \n6x=-11 \ \lor \ x=4 \nx=-(11)/(6) \ \lor \ x=4 \n\boxed{x=-1 (5)/(6) \hbox{ or } x=4}$

   (3x + 1)(2x - 5) = 39
      3x(2x - 5) + 1(2x - 5) = 39
3x(2x) + 3x(-5) + 1(2x) + 1(-5) = 39
      6x² + (-15x) + 2x + (-5) = 39
      6x² - 15x + 2x - 5 = 39
      6x² - 13x - 5 = 39
      - 39 - 39
      6x² - 13x - 44 = 0
          x = -(-13) ± √((-13)² - 4(6)(-44))
      2(6)
      x = 13 ± √(169 + 1056)
   12
      x = 13 ± √(1225)
   12
      x = 13 ± 35
      12
      x = 13 + 35 ∨ x = 13 - 35
      12    12
      x = 48    ∨       x = -22
      12    12
      x = 4    ∨        x = -1⁵/₆
The solution set us equal to {4, -1⁵/₆}.

3(-X+4)=7x-8. Yeahhhh...

Answers

Hey there!☺

$Answer:\boxed{x=2}$

$Explanation:$

$3(-x+4)=7x-8$

Let's start by simplifying both sides. First, we distribute.

$(3)(-x)+(3)(4)=7x+-8$

$-3x+12=7x+-8$

$-3x+12=7x-8$

Now let's subtract 7x from both sides.

$-3x+12-7x=7x-8-7x\n-10x+12=-8$

Now we will subtract 12 from both sides.

$-10x+12-12=-8-12\n-10x=-20$

In our last/final step, we will divide both sides by -10.

$(-10x)/(-10)=(-20)/(-10)$

Now simplify -20/-10.

$-20/-10=2$

$x=2$

Hope this helps!
