George tells you that when variables are in the denominator the equation 4/5 + 3 / x= 1 / 2 becomes unsolvable. george explains there is a value for x that makes the denominator zero and you can't divide by zero. demonstrate to george how the equation is still solvable explain your reasoning.

The westins and the shermans live in the same city and pay the same sales tax rate, and both families made $14,000 in taxable purchases last year. if the westins made $86,000 and the shermans made $33,000 last year, is the sales tax in their city an example of a regressive tax? yes, because the westins and the shermans both paid the same sales tax rate. b. no, because the shermans paid a higher percentage of their income in sales tax than the westins did. c. no, because the westins and the shermans both paid the same sales tax rate. d. yes, because the shermans paid a higher percentage of their income in sales tax than the westins did.
