Solve the proportion
2/r = 12/18​

r=3

Step-by-step explanation:

Divide the numbers

2/r=12/18

2/r=2/3

Multiply all terms by the same value to eliminate fraction denominators

rx2/r=rx2/3

simplify

2=2r/3

multiply all terms by the same value to eliminate fraction denominators again

3x2=3x2r/3

simplify

6=2r

divide both sides if the equation by the same term

6/2=2r/2

r=3

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
