Please indicate the question number, and the process should be detailed in questions 8 and 10

7.Solution: 32g-26g=6g

Set the volume to xcm3

x=30cm3

Alcohol = 30 cm3*

Water = 30cm3*

A: 30 grams of water, 24 grams of alcohol.

8.Solution: 10min=600s

Solution v approx. = A: The velocity is.

9.Solution: 54km h*1 1200h=

Set up a distance of mountain xm

x+(x-45m)]/340m/s=3s

x = A: Meters from the mountain.

10.Solution: y=x*(82-2) (80-4)+2-(82-2) (80-4)*4

x*80/76+2-80/76*4

When x=26.

y approx. = when x = y.

The solution is x=y=42

Answer: y =x*80 76+2-80 76*4; When the indication is 26, the actual temperature is; When the temperature is 42, the actual temperature is equal to the thermometer indication.

7.Water, alcohol.

Annoying question

The back one is too annoying, so I don't pull it

1b 2b 3a 4d 5b 6d 9 may be 191: (54 times 3 + 340 times 3) divided by 2

<> picture is cautious and cautious.

7, positive late attack negative one-third of the open tong. Siddan Tan 8, 2 9, 4 10, 243/5. 11,x is equal to two or zero. y is equal to three.

2. Question 11: 10a+7

12 questions: minus 1/2

Question 13: 1 2

Question 14: Question 615: A(1-x).

Question 16: 4

17 questions: 30 yuan.

Question 18: 5

Proof: 1= 2, aed= afd=90°, ad=ad

aed≌⊿afd(aas),ae=af.

ae=af,∠1=∠2.

AD bisects ef. perpendicularly(Isosceles triangle.)"Three-in-one")

It's so late that I still do my homework, admire, admire, admire, admire, admire.

Why don't you do it yourself?
