answer:Albert has already completed 6 laps around the track, which is a total of 6 * 9 = 54 meters. He needs to run a total of 99 meters, so he has 99 - 54 = 45 meters left to run. Since each lap is 9 meters, he needs to run 45 / 9 = 5 more complete laps. 5 The answer is: 5

answer:We can start by breaking the equation into three cases, depending on the signs of x-20 and x-18: Case 1: If x le 18, then |x-20| = 20-x and |x-18| = 18-x, so the equation becomes [(20-x)+(18-x) = |2x-36|.] Simplifying, we get 38-2x = |2x-36|. Since x le 18, we have 2x le 36, so |2x-36| = 36-2x. Substituting, we get 38-2x = 36-2x, which has no solution. Case 2: If 18 le x le 20, then |x-20| = 20-x and |x-18| = x-18, so the equation becomes [(20-x)+(x-18) = |2x-36|.] Simplifying, we get 2 = |2x-36|. Since 18 le x le 20, we have 36 le 2x le 40, so |2x-36| = 2x-36. Substituting, we get 2 = 2x-36, so x = 19. Case 3: If x ge 20, then |x-20| = x-20 and |x-18| = x-18, so the equation becomes [(x-20)+(x-18) = |2x-36|.] Simplifying, we get 2x-38 = |2x-36|. Since x ge 20, we have 2x ge 40, so |2x-36| = 2x-36. Substituting, we get 2x-38 = 2x-36, which has no solution. Therefore, the only solution is x = boxed{19}. The answer is: 19

answer:If Tyrah has 6 times as many pencils as Sarah, and Tyrah has 12 pencils, then Sarah has 12/6 = 2 pencils. If Tim has 8 times as many pencils as Sarah, then Tim has 8*2 = 16 pencils. Therefore, Tim has 16 pencils. 16 The answer is: 16

answer:In January, James earned 4000. In February, James earned twice that amount, so he earned 2 * 4000 = 8000. In March, James earned 2000 less than he did in February, so he earned 8000 - 2000 = 6000. To find the total amount James earned for the year, we add up the earnings from each month: 4000 + 8000 + 6000 = 18,000. 18000 The answer is: 18000
