WebLet us find the number of computers sold for no profit. That is, find the value of "x" when y = 0. Substitute y = 0 in the equation y = 27x - 10,000. 0 = 25x - 10,000. Add 10,000 to both sides. 10,000 = 25x. Divide both sides by 25. 400 = x. Step 3 : When Lily sells 400 computers in a month, her profit is equal to zero. navfac engineering command hawaiiWebThe relationships described in equation form are as follows: x+x+ 2+x+4 = 246 x + x + 2 + x + 4 = 246 Which reduces to: 3x + 6 = 246 − 6 −6 3x = 240 x = 240 3 or 80 3 x + 6 = 246 − 6 − 6 3 x = 240 x = 240 3 or 80 This means that the three consecutive even integers are 80, 82, and 84.
