Answer:

la respuesta es x=3

Step-by-step explanation:

2x−8+7x=19

2x+−8+7x=19

(2x+7x)+(−8)=19

9x+−8=19

9x−8=19

9x−8+8=19+8

9x=27

Step 3: Divide both sides by 9.

9x9=279

2. 4x - 2y = -6<br> -6x + 2y = 2
Phoenix [80]

Answer:

x = 2, y =7

Step-by-step explanation:

4x - 2y = -6

-6x + 2y = 2

Add the equations together

4x - 2y = -6

-6x + 2y = 2

-----------------------

-2x = -4

Divide each side by -2

-2x/-2 = -4/-2

x = 2

now find y

-6x+2y =2

-6(2) +2y =2

-12+2y =2

Add 12 to each side

-12+12+2y = 2+12

2y =14

Divide by 2

2y/2 =14/2

y =7

Determine how Marilyn’s net pay will be affected if she increases her federal withholding allowances from 3 to 4. a. Her net pay
noname [10]

The missing texts where highlighted in bold format.

Marilyn has a biweekly gross pay of $810 and claims 3 federal withholding allowances. Marilyn has all of the following deductions from her gross pay: federal tax from the following table

Social Security tax that is 6.2% of her gross pay

Medicare tax that is 1.45% of her gross pay

state tax that is 21% of her federal tax

Determine how Marilyn’s net pay will be affected if she increases her federal withholding allowances from 3 to 4.

a. Her net pay will increase by $15.00.

b. Her net pay will decrease by $15.00.

c. Her net pay will increase by $18.15.

d. Her net pay will decrease by $18.15.

Answer:

c. Her net pay will increase by $18.15.

Step-by-step explanation:

From the given information; we can compute the deduction on her gross pay.

given that;

gross pay = $810

Social Security tax that is 6.2% of her gross pay

i.e

\dfrac{6.2}{100} * 810= 50.22

Medicare tax that is 1.45% of her gross pay

= \dfrac{1.45}{100}*810=11.745

state tax that is 21% of her federal tax

we are given that her federal withholding allowance is 3

= \dfrac{21}{100}*3=0.63%

The state tax that is 0.63% of her gross pay

=\dfrac{0.63}{100}*810= 5.103

The total deducted amount of Marilyn’s gross pay = 50.22 + 11.745 + 5.103 = 67.068 of his gross pay

= 810 - 67.068 = 742.932

However; the question proceeds by saying ; if she increases her federal withholding allowances from 3 to 4; we should Determine how Marilyn’s net pay will be affected.

SO;

If the federal withholding allowance is 4

Then;

= \dfrac{21}{100}*4=0.84%

The state tax that is 0.84% of her gross pay

=\dfrac{0.84}{100}*810 = 6.804

Thus; from the foregoing :

c. Her net pay will increase by $18.15.
