Alex787 [66]

Answer:

$15,267

Step-by-step explanation:

Kay earns $78,400 per year and gets a standard deduction of $5,700.

Her taxable income is amount of money that she can pay tax on and that is:

Income - Standard Deduction

= $78,400 - $5,700 = $72,700

She pays tax at a 21% rate, hence, her income tax is:

\frac{21}{100} * 72,700

= $15,267

Her income tax is $15,267.

Help me on this math problem please! I’ve been stuck on it for 15 mins now
Reil [10]

Answer:

Step-by-step explanation:

P = perimeter = 114

P =2 * length +2* width

P = 2(2x - 3) + 2(x)

114 =  4x-6  + 2x

114 = 6x -6

19 = x -1

20 = x

check it  

2( 2x -3)+2x =  ?  

4x -6 +2x=?

6x -6 = ?

6(20)-6 =?

120-6 = 114

yep this is correct

11. A line through points (-5, 2) and (2, y) has a slope of 3.<br> Find y.<br> Help
allochka39001 [22]

Answer:

23

Step-by-step explanation:

  • Create an equation to find y:  3 = \frac{y-2}{2-(-5)}
  • Calculate by adding:  3 = \frac{y-2}{7}
  • Multiply both sides of the equation by 7 : 21 = y - 2
  • Move the variable to the left-hand side and change its sign : -y + 21 = -2
  • Calculate and change signs : y = 23

                                                             y = 23
