4 (10) of 40%.

5 Their area is (square decimeter).

6 Accuracy rate (90%)

7 (with x bicycles, 2x+3(15-x)=36, 9 bicycles), 8 small (51) pages.

1: Ten correct answers.

2: 28 males and 22 females.

3: The number A is (45), and the number B is two numbers (120).

4:16 of 1 4 is 40% of (10).

6: Xiao Ming did oral arithmetic problems, did 20 questions, got two questions wrong, and the correct rate (90%)

The first question is the equation Let the correct answer x answer and the wrong answer y can be obtained from the meaning of the question: x+y=12 (1).

10x-5y=90(2)

Solution: x=12-y(3).

Substitute Eq. (3) into Eq. (2).

It becomes a one-dimensional equation.

10（12-y)-5y=90

The solution is y=2 and y=2 is substituted into equation (1).

The solution is x+2=12

So x=10

y=2A: 10 things are done correctly and 2 things are wrong.

This is the solution to the first problem, and it's very detailed

The number A is 3 5 of the number B, the number B is 75, and the number A is (75*3 5 = the number of A).

The circumference of a circle is decimeter, and their area is (3*3*).

It is the best way to buy a group ticket.

Non-group: 36*8=288 yuan.

Group: 40*8*RMB.

288-256 = 32 yuan So save 32 yuan.

Buy a group ticket and give the remaining 4** to someone else.

40*8=320 (yuan) 320*1 5=64 (yuan) 320-64=256 yuan 4*8=32 yuan 256-32=224 yuan.

You can save 64 yuan.

36*8=288 yuan 288-224=64 yuan.

I mean: you can look at the first person, the second person though in real life is the most cost-effective. But you can't do that. Can only be done like the first floor!

Question 8 is wrong, right?

1.360*1 6=60 tons Day 2: 60*1 4=16 tons2

600*1 5=120 kg.

Apple: 600*3 10=180 kg.

Total: 120 + 180 = 300 kg.

Oranges are 180-120 = 60 kg less than apples.

Others: 600-300 = 300 kg.

5 350 * 3 7 * 4 5 = 120 kg.

6 65*2 5=13*2=26 people.

7 120 * (1 + 2 3) + 7 = 207 sheets.

1.On the first day, 360*1 6=60 tons were transported.

The next day, (360-60) * 1 4 = 75 tons * (1-1 3-1 4) = 5004, a total of 600 * (3 10 + 1 5) = 300 oranges are 600 less than apples 600 * (3 10-1 5) = 60 other fruits 600 * (1-3 10-1 4) = 3005, 350 * 3 7 * 4 5 = 120

8. There is an error in the question.

There was an expedition unit, they were shipwrecked and drifted to a desert island, on this desert island, there was a strange tribe, and the natives of these tribes caught strangers and asked them to say a word, and then these natives would analyze whether the person was telling the truth or false, and if it was true, the natives would take this stranger to the goddess of truth to the east of the tribe and kill him, and if it was a lie, the natives would take him to the goddess of lies to the west of the tribe and kill him, and for many years, no one was spared, This time, in the midst of this expedition, there was a man who said a word, and in the end, the natives decided to let him go, and guess what this person said?
