Aman realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. if the after-tax total was $1,814.31, and the tax rate in the area is 6.1%, what was the pre-tax subtotal?

  $1710.00

Step-by-step explanation:

The total bill was ...

  (after-tax total) = (pre-tax subtotal) + 6.1% · (pre-tax subtotal)

  (after-tax total) = (pre-tax subtotal) · 1.061

Divide by the coefficient on the right to find the value of the variable on the right.

  (pre-tax subtotal) = (after-tax total)/1.061 = $1814.31/1.061 = $1710.00

The pre-tax subtotal was $1710.00.

i pretty sure it is

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
