Question 1038523: Kindly help please.
Politics. The percentage s of seats in the House of Representatives won by Democrats and the percentage v of votes cast for Democrats (when expressed as decimal fractions) are related by the equation
5v - 2s = 1.4 0 < s < 1, 0.28 < v < 0.68
(A) Express v as a function of s, and find the percentage of votes required for the Democrats to win 51% of the seats.
(B) Express s as a function of v, and find the percentage of seats won if Democrats receive 51% of the votes.
