answer:If the whole pizza was cut into 8 slices, and Angeli and Marlon each ate 3/2 slices, then they ate a total of 3/2 + 3/2 = 6/2 = 3 slices. If there were originally 8 slices and they ate 3 slices, then there are 8 - 3 = 5 slices of pizza left. 5 The answer is: 5

answer:We know that x^2 = 729. Taking the square root of both sides, we get x = sqrt{729}. Since x is positive, the value of x is boxed{27}. The answer is: 27

answer:To solve this problem, we need to determine the value of x, which represents the number of days it rained. On the first day, the rain poured heavily from 7:00 to 17:00, which is a total of 10 hours. On the second day, the rain took 2 more hours than the first day to stop, so it rained for 10 + 2 = 12 hours. On the third day, the rain poured for twice the amount of time it took on the second day, so it rained for 12 * 2 = 24 hours. To find the total time it was raining in x days, we add up the time for each day: 10 + 12 + 24 = 46 hours Therefore, the value of the unknown variable x is 3. It rained for 46 hours in 3 days. 3 The answer is: 3

answer:To solve this problem, we need to determine the value of x, which represents the number of fish Ellianna cooked and served for each type. Let's break down the information given: Amount of fat in a herring: 40 oz Amount of fat in an eel: 20 oz Amount of fat in a pike: 10 oz more than an eel Total amount of fat served: 3600 oz We can set up the equation as follows: (Number of fish of each type * Amount of fat in a herring) + (Number of fish of each type * Amount of fat in an eel) + (Number of fish of each type * Amount of fat in a pike) = Total amount of fat served x * 40 + x * 20 + x * (20 + 10) = 3600 Let's simplify and solve for x: 40x + 20x + 30x = 3600 90x = 3600 To isolate x, we divide both sides of the equation by 90: 90x / 90 = 3600 / 90 x = 40 The value of x is 40. 40 The answer is: 40
