T=4p/q+2 is known. If T=8 and q=-5, Find p. Situation 1: T = 4p/(q+2) ... Substitute T = 8 and q =-5: ... 8 = 4p/(-5+2) ... 8 = 4p/(-3) ... 4p =-24 ... p =-. Let the smallest number be n, then the other two numbers are (n+ 1) and (n+2). N+(n+1)+(n+2) = 243n+3 = 243n = 21n = 7 Minimum number = 7 In a quiz, you can get 5 points for each correct answer and deduct 3 points for each wrong answer or abstention. If this game has 10 questions, how many questions are answered correctly if the score is less than 44 points? Set the answer to question n correctly. Number of questions answered incorrectly or abstained = (10-n) Question 5n-3 (10-n) = 445n-30+3n = 448n = 74n = 9.25 Because n is not an integer, the question has no solution. Solve the problem in the same way. If you get 42 points, if everything else remains the same, you will answer 9 questions correctly. If you get 34 points, if everything else remains the same, you will answer 8 questions correctly. If you are wrong or abstain, only 1 point will be deducted for each question. If everything else remains the same, you will get nine questions right. )

1.t = 4p/q+28 =-4p/5+2-4p/5 = 6-4p = 30p =- 15/22。 The smallest number is x, the middle number is x+ 1, and the largest number is x+2x+(x+).

Because if there are less than 8 questions, 10-8=2 questions, 8*5-2*3=34 5=44, the third question you wrote may be (in a quiz, you can get 5 points for each correct answer and 3 points for each wrong answer or abstention). If this game has 12 questions, and the score is less than 44 points, how many questions are correctly answered? ) There is a solution. 5x-3 (12-x) = 445x-36+3x = 448x = 80x = 10a (possible): less than10.

T=4p/q+2 is known. If T=8 and q=-5, find p.t = 4p/q+28 = 4p/(-5)+28 = 4p/-3-24 = 4pp =-6 If the sum of three consecutive numbers is 24, find the smallest number. Let the smallest continuous number be y.

Then the second consecutive number is (y+ 1)

The largest hyphen is (y+2) y+(y+1)+(y+2) = 243y+3 = 243y = 21y = 7, so the smallest number is 7. In a quiz, you can get 5 points for each correct answer, and deduct 3 points for each wrong answer or abstention. If this game has 10 questions, how many questions are answered correctly if the score is less than 44 points? Suppose you can't answer question a correctly.

Wrong answer or abstention (10-a) because you can get 5 points for each correct answer, and deduct 3 points for each wrong answer or abstention. 5 (a)+[-3 (10-a)} = 445a-30+3a = 448a = 74, so my question system is: {If this game has {12} questions, how many questions are answered correctly if the score is less than 44 points? } If it is ... I will set the question a little smaller than the answer to question A first.

Then the wrong answer or abstention (12-a) is less than 5 points for each correct answer and less than 3 points for each wrong answer or abstention (5 (a)+[-3 (12-a)} = 445a-36+3a = 448a = 80a =/kloc- If T=8 and q=-5, finding p. Q seems to be written as =-5 2009-08-017:18:14. Supplement: Your third question ... because the number of correctly answered questions must be an integer. ...
