Ajar contains n nickels and d dimes. there are 27 coins in the jar, and the total value of the coins is $1.85. set up and solve a system of equations to find how many nickels and how many dimes are in the jar.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
