150 points will be added for a good answer, and 100 points will be added for one article

Question 1: Let the number of boys be x and the number of girls be y y (x-15)=2 1 , (y-45) (x-15)=1 5

The simultaneous solution is y=40

Question 2: Set the first shelf for x books, and the second layer for y x 4=2y 5, x-y=120

The simultaneous solution is y=200

Question 3: Let A remember x words a day, and B remember y x-y=22, (40-15)x=2y

The simultaneous solution is y=10, so 40y=400

Question 4: Let Xiao Ming have the original x book, and Xiao Fang has the y book x=6y, x-2=8(y-2).

Simultaneous solution x=42

Question 5: Let Xiao Ming be x-yuan, Li Qiang y-yuan (x-3) y=2 5, x (y-3)=8 13

Simultaneous solution x=12

Question 6: Let the distance be x m x 60 + x 80 = 21

Solution x=720

If this is an assignment question, the narrative can't be so simple, be clear!

1.Let the girl be x and the boy be y

x-15/y=1/2

x-15/y-45=5/1

Get x= y=

2.Set one bookshelf as x and two bookshelves as y

1/4*x=2/5*y

x-y=120

No, I'm really not in the mood.

Children's math problems, use their own brains!

There are three types of test paper scores: excellent, good, and failing

Excellent, that is, the score is more than 80% of the total score of the test paper, and the score of 120 points is excellent; Good, i.e. a mark between 60% and 80% of the total mark of the paper, a 120-point paper, a score of 72 to 96 is good; Fail, i.e. the score is less than 60% of the total score of the paper, and the score of 120 points is less than 72 points.

It seems that what I know is that getting 60% of the score is passing, 80% good, 90% excellent, so 100 points, 60 points, passing, 80 points, 90 points, excellent, 120 points, 72 points, 96 points, good, 108 points, excellent, 150 points, 90 passing, 120 points good, 135 points excellent, I hope it can help you.

A pass score of 100 is 60 points, a good score is 80 points, and an excellent score is 90 points: a passing score of 150 points is 90 points, a good score is 120 points, and an excellent score is 135 points; A passing score of 120 is 72 points, a good score is 96 points, and an excellent score is 108 points.

A paper with 100 points is 60 points to pass, 150 * 60% = 90 (points) 90 points are to pass.

Set x points to pass. Because when 100 points, 60 points are considered passing, so there are 60 100 = x 150, and solving the above equation, x = 150 * 60 100 = 90, so 150 points for the question, 90 points are considered passing.

A passing score of 100 is 60 points, a good score is 80 points, and an excellent score is 90 points. A pass score of 150 is 90 points, a good score is 120 points, and an excellent score is 135 points.

60% of the total score is a passing grade, 150x60% = a passing grade.

This is calculated as a percentage, and a passing grade is good when it is excellent.

Summary. 150 points pass: 150 points or more Excellent: 150 points or more.
