Answer:

x=-7, y=-5. (-7, -5).

Step-by-step explanation:

2y+x=-17

5x-4y=-15

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

x=-17-2y

5(-17-2y)-4y=-15

-85-10y-4y=-15

-85-14y=-15

14y=-85-(-15)

14y=-85+15

14y=-70

y=-70/14

y=-5

2(-5)+x=-17

-10+x=-17

x=-17-(-10)

x=-17+10

x=-7

Answer:

x=14.5

Step-by-step explanation:

since we know the sum of a triangles interior angles equal 180, we can subtract 66 from 180

180-66=114

6x-8+2x+6=114 - combine like terms

8x-2=114 - add 2 to both sides

8x=116 - divide by 8

x=14.5

angle a= 79

angle n=35

John has gross biweekly earnings of $743.61. By claiming 1 more withholding allowance, John would have $19 more in his take home

Afina-wow [57]

Answer:

Total withholding allowances are 39.

Step-by-step explanation:

Given the gross earning of John = $743.61

It is given that 1 withholding allowance = $19

Now we have to find the total number of withholding allowances. Here, the number of withholding allowances can be determined by dividing the total earnings with $19.

Number of withholding allowances = 743.61 / 19 = 39.14 or 39 (round off).
