0x27=0 1x27=27 2x27=54 3x27=81 4x27=108 5x27=135 6x27=162 7x27=189 8x27=216 9x27=243 10x27=270 11x27=297 12x27=324
To find the value of ( n ) in the equation ( 9 \times 27 + 2 \times 31 - 28n = 0 ), first calculate ( 9 \times 27 = 243 ) and ( 2 \times 31 = 62 ). Combining these gives ( 243 + 62 = 305 ). Setting the equation ( 305 - 28n = 0 ) leads to ( 28n = 305 ), so ( n = \frac{305}{28} ), which simplifies to approximately ( 10.89 ).
