two numbers are in the tatio 2:3. when 4 is added to each number the ratio changes to 5:

7.the sum of the two original numbers is

The ratio of two numbers is 2:3, and when 4 is added to each number, the new ratio of two numbers is 5:7, and the sum of the original two numbers is found

Suppose the original number is x y

x/y=2/3 >>3x=2y >>x=2y/3

x+4)/(y+4)=5/7 >>7x+28=5y+20 >>14y/3+28=15y/3+20

y/3=8y=24

x=16, so the sum of the original two numbers is 24+16=40

The ratio of two numbers is 2:3, and if each number is added by 4 the ratio is 5:7, then the sum of these two numbers is equal to: 40

【b】754

The answer is (a+b+c) n+m 10+700, where a, b, and c represent the numbers in the three corners, n means the numbers repeat n times, and m means there are m different numbers.

Figure 1: (5+5+6) 2+2 10+700=728Figure 2: (8+6+8) 2+2 10+700=731Figure 3: (9+7+8) 1+3 10+700=754

the woman is a photographer. she shot/took a picture of him, develops it and hang it.

The previous words shoot, holds him under water, and hang are all polysemous words, and their meanings in photography are different from ordinary meanings.

Ordinary Significance: The woman has killed her husband.

Meaning of Photography Terminology: The previous description is the whole process of the woman taking ** for her husband, developing the photo, and hanging the photo.

If you don't know the photographic meaning of these words, you end up wondering: how can the husband come out together to share dinner after his wife has already killed him?

2.Something I love.

america/the usa.or"in Washington".

1.I don't know...

2.Not what I love.

3.The third person thinks the answer is the United States?

1. school

2.Hobby.

3. america

4.Looks like there should be a picture.

2。Things I love.

3。The White House in Washington 4

4。Hehe, I didn't make it myself, I'm sorry.

1.When I am full, I can show the way. When I'm empty, I can't move. I have two sides, one inside and one outside. Who am I?

2.Is it possible for a woman to have 7 children, and exactly half of them are boys?

Answer: 1glove (gloves).

2. all the children are boys,so half are boys and the rest are boys is possible.(All boys, of course half boys, the other half are boys).

woman has 7 children ,and exactly half of them are boys,how is this possible?

She gave birth to half of a boy, half of a girl, and 1 in the womb of a boy or a girl.

The first one I don't know, the second one I feel is the problem with them, they refer to the 8 people in front of them, right? A woman and 7 children, half of them are 4, 4 boy boys. I don't know if it's right, hehe.

1 A glove reference.

I don't know why2 who knows, they could all be boys you didn't say just half.Do you understand?

The answer means who knows, they might all be boys, and you didn't say "only half" references.

If I understand correctly, the meaning of the title is: There are 4 men, and each man has a son. The four sons were asked to go into a dark room.

Then these 4 fathers go into the room and each bring out a child, what are the odds that they will bring their own son out?

Then it's a math problem, not an intellectual one.

The chance is 25%.

The ratio of the two numbers is 2:3, and when 4 is added to each number, the new ratio of the two numbers is 5:7, and the sum of the original two numbers is found

The original number of holes in the town is x

yx/y=2/3

3x=2yx=2y/3

x+4)/(y+4)=5/7

7x+28=5y+20

14y/3+28=15y/3+20

y/3=8y=24

x=16, so the sum of the original two numbers is 24+16=40

Hope it helps.
