DochEvi [55]

Answer:

we predict 2,587 persons will adopt dogs

Step-by-step explanation:

out of 40 persons 23 adopt dogs

Then

out of 40×25 persons 23×25 adopt dogs

Then

out of 1000 persons 575 adopt dogs

Then

out of 1000×4.5persons 575×4.5 adopt dogs

Then

out of 4,500 persons 2,587.5 adopt dogs  

Method 2 :

Let x Ben the number of persons we predict they will adopt dogs:

Here we have a proportional relationship:

Then

\frac{4500}{40} =\frac{x}{23}

\Longleftrightarrow x = \frac{4500\times 23}{40} =2587.5

Billy is 6 years younger than Amy. The sum of their ages is 22. How old will each of them be in 8 years?
Dafna11 [192]
First let's find their current ages:
Billy + 6years = Amy
Billy + Amy = 22

Combining these equations:
Billy + (Billy + 6years) = 22
2 Billy = 16
Billy = 8

Billy + 6 = Amy
8 + 6 = Amy
Amy = 14

In 8 years Billy will be 16 and Amy will be 22. The answer is d.

Write an equation and solve: Your math homework has 6 more than three
lorasvet [3.4K]

Answer: 33 math problems.

Step-by-step explanation:

Let x = Number of math problems

y= Number of history problems

According to the question , we have

3y+6=x\ \ \ \ \ (i)\\\\ x+y=42\ \ \ \ (ii)

We can rewrite (i) as x-3y=6    (iii)

Now, subtract (iii) from (ii), we get

y-(-3y)=42-6\\\\\Rightarrow\ y+3y=36\\\\\Rightarrow\ 4y=36\\\\\Rightarrow\  y= \dfrac{36}{4}\\\\\Rightarrow\  y=9

Put this in (i), we get

x=3(9)+6 = 27+6=33

Hence, you have to complete 33 math problems.
