0.07x = 35....with x being the cost of the stereo
Because -2x+4+2x-4=0, the additive inverse is (2x-4)
The number of ways is 497420
The ways can the team assign field positions to 9 of the 22 players, putting each of the 9 selected players in a position he can play, and ensuring that all 9 field positions are filled is
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

• 2 x 10^5 = $200,000
• $200,000 * 8 years = $1,600,000
• $1,600,000 = 1.6 x 10^6
Simple,
x= ln(2)/4 ln(7)+ln(5)/4 ln(7)
x=0.29582367
or rounded,
