Answer: X=-3.

Anne was correct at fist, but likely didn’t solve the rest of the equation. The correct answer is X=-3, from 5(2x - 3)= 20x + 15, simplified by the distributive property going to 10x - 15 = 20x + 15. You then subtract +15 from the right side, or left side if you want to have a more positive answer, though it depends. That leaves you with 10x - 30 = 20x. You subtract 10x from itself and from 20x. Then you have -30 = 10x. You divide 10x by -30, and you get -3. Therefore, X = -3.

the gross earnings • group health insurance (assuming 15% of gross earnings) pension deduction (assuming 6.5% of gross earnings)

sveta [45]

Step-by-step explanation:

<u>Calculate the gross earnings:</u>

40*7.75 = 310.00

<u>Health insurance deduction:</u>

310.00*15/100 = 46.50

<u>Pension deduction:</u>

310.00*6.5/100 = 20.15

<u>Total deductions:</u>

55.00 + 15.50 + 21.25 + 46.50 + 20.15 = 158.40

<u>Net pay:</u>

310.00 - 158.40 = 151.60

Please answer! this is an important exam that im taking right now.

Answer:

Required ordered pair is (0,0) for system of equation

Step-by-step explanation:

The given system of equation is

A). $9^{12x} = 9^{3y}$

B). $y^{4} - 9y^{2} x^{2} =16y$

On simplifying the equation A

$9^{12x} = 9^{3y}$

Take log on both side,

(12x) (log9) = (3y) (log9)

4x=y

To find the solution of the system of the equation :

Replacing value of y=4x in equation B,

$y^{4} - 9y^{2} x^{2} =16y$

$(4x)^{4} - 9(4x)^{2} x^{2} =16(4x)$

$256x^{4} - 144x^{2} x^{2} =64x$

$256x^{4} - 144x^{4}=64x$

$112x^{4}=64x$

We get,

x=0 and x=0.829

Since, 0.829 is not integer number

Only solution of equations is x=0

For the value of y

Replace value x in y=4x=0

Thus, Required ordered pair is (0,0)
