Here, you could make a proportion. 

 6      x
---- x ----
30    100 

6 * 100 = 600
30 * x = 30x

600 / 30 = 20

Hi!

So we know that there are 30 people over 100, and 6 of them are male. That means the the rest are female. We just have to find out how much the rest is. 

To do that, we subtract
30-6 = 24

The answer is 24.

Hope this helps! :)

Which list contains values that are all part of the solution set of the graphed inequality? 2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1.
olya-2409 [2.1K]

The inequality is,

0\leq x\leq 2001.3

we have given that the solution set

2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1. 1, 1. 5, 19. 7, 8. 2 11, 1, 48. 5, 7.

here we have given that all the values of x are positive and

Which is the smallest point in above set?

0

and

Which is the highest point in the above set?

2001.3

Therefore,

we have a=0 and b=2001.2

Our equality lie in a and b

Therefore,

a\leq x\leq b

Plug the value of a and b we get

0\leq x\leq 2001.3

Therefore we get the inequality is,

0\leq x\leq 2001.3

Solve the system of linear equations by substitution
ziro4ka [17]

y - x = 0  ...equation 1
2x - 5y = 9 \: ...equation  \: 2
working with equation 1
y = x \: ...equation \:  3
next subsitue equation 3 in equation 1
2x - 5(x) = 9
2x - 5x = 9
- 3x = 9
divide by -3
x =  - 3
substitute x= -3 in equation 1
y - ( - 3) = 0
-(-3) = + 3
y =  - 3

PLEASE HELP !!!

<h3>Answer: D. 80% of the home’s value</h3>

============================================================

Explanation:

As you probably expect, the first number 80 refers to the percentage the first loan covers. If the house is say $100,000, then the first loan is $80,000 while the second loan is the remaining $20,000.

An 80/20 mortgage, or similar, will have two monthly payments because you are getting two mortgages bundled together. Usually you should pay a down payment, though it may likely depend on your credit history. Those with good credit will pay less or no down payment, compared to those with worse credit will have to pay more down payment. A good rule of thumb is that 20% of the home's value is made as down payment, though this isn't what the "20" in "80/20" is referring to.

An 80% down payment is extremely high and unreasonable. Not many people have that kind of money laying around. A similar story applies to a 20% interest rate which is incredibly large for a mortgage rate (typically they are in the single digits such as 3%).
