<h3>Given</h3>

\dfrac{x+5}{2}+\dfrac{x+6}{2}

<h3>Find</h3>

The simplified form

<h3>Solution</h3>

There are a couple of possibilities, depending on whether you insist on a common denominator.

\dfrac{x+5}{2}+\dfrac{x+6}{2}=\dfrac{(x+5)+(x+6)}{2}\\\\=\dfrac{2x+11}{2}\qquad\text{one possible representation of the sum}\\\\=x+\dfrac{11}{2}\qquad\text{another representation of the sum}

Whitepunk [10]
Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)

(2) x 2 => 2x + 6y = 112 . . . (3)

(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17

The two numbers are 13 and 17.

\text{State Income Tax Rate: }6.65\%, \\\text{Deduction: }\$7,702.03

Answer:

State income tax: 6.65\%

Step-by-step explanation:

Based on the interface, it seems like you have chosen lawyer as a career with the given salary of $115,820.

The chart given for state income tax is broken into two categories:

$21,400-$80,650 => 6.45%

$80,651-$215,400 => 6.65%

Since the chosen career's salary is $115,820, the career falls into the second range of 6.65% state income tax.

The deduction is simply the amount of money taxed. For a 6.65% state income tax, the deduction can be found from:

115,820\cdot 0.0665=\boxed{\$7,702.03}
