We can solve this system by substitution: if 2x - y = 4, we can manipulate this to arrive at: => 2x - 4 = y Substitute in 2x - 4 to the second equation wherever we see a y: If: 2x - y = 3 => 2x -(2x - 4) = 3 => 2x - 2x + 4 = 3 => 4 = 3 ... This is
.32(1,000) = x => x = 320.
OK, so selecting five numbers at random, I will use: 75, 76, 83, 91, 87 Mean: (75 + 76 + 83 + 91 + 87)/5 = 82.4 Median: is the middle number, so 83. Mode: is the number which repeats the most, so since no numbers repeat, there is no mode. Midrange: is the
.40(x)=82 => x = 82/(.40) => x = 205
