question:Jairus read 20 pages of the newspaper. Arniel read 2 more than twice the number of pages Jairus read. How many pages have they read altogether?
answer:Twice the number of pages Jairus read is 20 x 2 = 40 pages. Arniel read 2 more than twice the number of pages Jairus read, which is 40 + 2 = 42 pages. Therefore, Jairus and Arniel read a total of 20 + 42 = 62 pages. 62 The answer is: 62
question:f the product of 5! and 3! is equal to n!, what is the value of n?
answer:We have 5! cdot 3! = n!. Simplifying, we get 120 cdot 6 = n!. This gives us 720 = n!. The only value of n for which n! = 720 is n = boxed{6}. The answer is: 6
question:f Mark is four years older than Billy and Billy is half of Ana's age, and Ana will be 15 in 3 years, what is Sarah's age if it is equal to three times Mark's age minus 4?
answer:If Ana will be 15 in 3 years, then currently she is 15 - 3 = 12 years old. If Billy is half of Ana's age, then Billy is 12 / 2 = 6 years old. If Mark is four years older than Billy, then Mark is 6 + 4 = 10 years old. If Sarah's age is equal to three times Mark's age minus 4, then Sarah's age is 3 * 10 - 4 = 26 years old. 26 The answer is: 26
question:the second hour of a storm it rains 7 inches more than twice the amount it rained the first hour. The total amount of rain in the first two hours is x inches. It rained 5 in the first hour. What is the value of unknown variable x?
answer:To solve this problem, we need to determine the value of x, which represents the total amount of rain in the first two hours. We know that it rained 5 inches in the first hour. In the second hour, it rained 7 inches more than twice the amount it rained in the first hour. Twice the amount it rained in the first hour is 2 * 5 = 10 inches. Therefore, in the second hour, it rained 10 + 7 = 17 inches. The total amount of rain in the first two hours is 5 + 17 = 22 inches. Therefore, the value of the unknown variable x is 22. 22 The answer is: 22
