Step-by-step explanation:
We have 5x + 4y = 87 and x + y = 20.
=> 5x + 4y = 87 and 4x + 4y = 80.
5x + 4y = 87
- (4x + 4y = 80)
=> x = 7
Therefore (7) + y = 20, y = 13.
The answers are x = 7 and y = 13.

A city has a population of 400,000 people. Suppose that each year the population grows by 6%. What will the population be after 11 years? Use the calculator provided and round your answer to the nearest whole number.
Answer:
773,917
Step-by-step explanation:
I will assume it will be a compound interest:
To solve any compound interest problems, use the formula (P x e)^r x t
P = Principal amount
e is Euler's number can be found on your calculator
r = rate
t = time
so 400,000e^0.06 x 11 = 773,916.93 = 773,917 (round to the nearest whole number)
Answer:
pop after 11 years will be 772,000
Step-by-step explanation:
P = initial population · [tex]e^{(.06)(11)}[/tex] e = Eulers number which is approx 2.7
P = 400,000 · [tex]2.7^{0.66}[/tex]
P = 400,000 · 1.93
P = 772,000

2x+y=-4
-3y=2x+12
Answer: 3y=12−2x 3 y = 12 - 2 x
Step-by-step explanation:
Answer:
Let
2x+y=-4——(1)
-3y=2x+12
2x+3y=-12—-(2)
Deduct eqt 1 from 2
(2x+3y=-12)
-(2x+y=-4)
2y=-8
y=-4
Put y=-4 into eqt 1
2x-4=-8
2x=-8+4
2x=-4
Divide both sides by 2
x=-2
:. x,y= -2,-4

a person can pay 14$ for a membership to the science museum and then go to the mesum for just 1$ per visit what is the maxium number of visits a member of the science museum can make for the total cost of 43$
Answer:
I think 43 visits
Step-by-step explanation:
I hope this helps you and I hope this is right and have a wonderful day:)
Hello! I won't give you the answer but I'll show you an example to a similar question like that!
Okay, so what if: a person can pay $6 for a membership to the art museum and then go to the museum for just $1 per visit. what is the maximum number of the art museum can make for a total cost of $18?
An easy way to solve this is to make an equation.
Let's call the number of times we can visit "x".
So, we pay $6 off the bat, and then pay $1 per visit after.
6+1x
That's the cost associated with visiting "x" number of times, now, we need to know how many times we can visit for 18, so we equate the expression to 18.
6+x=18
x=12
We can visit 12 times.
I hope this helps and that now you know the problem is supposed to be solved!
See ya later, pal!

Describe the features of the Free-market system
Answer:People often use the terms free enterprise, free market, or capitalism to describe the economic system of the United States. A free enterprise economy has five important characteristics. They are: economic freedom, voluntary (willing) exchange, private property rights, the profit motive, and competition.
Step-by-step explanation:
Answer:
Feature 1 # Property Rights:Property rights are social institutions that govern the ownership, use and disposal of resources, goods and services.
Feature 2 # Freedom of Private Enterprise:Allied to the property rights is freedom of enterprise which is another basic feature of a market economy. Freedom of enterprise means that everybody is free to engage in whatever economic activity he pleases. In other words, he is free to choose to work in any industry he likes or adopts any occupation or trade he desires.
Feature 3 # Profits and Prices: Incentives and Information:No individuals would work and save if adequate incentives are not provided to them in the form of wages and interest respectively. Similarly, the firms will not produce goods and services and bear risk of losing money if sufficient incentives are not given to them. Profits are earned from undertaking the task of producing goods and services and introducing new products and new techniques of production. Profits earned by the firm depend on prices of goods and services produced and cost incurred.
Feature 4 # Competitive Markets:In ordinary speech the word market means a place where buyers and sellers meet to buy and sell goods. In economics, market has a wider meaning and is interpreted to mean any arrangement that enables buyers and sellers to exchange things; they may contact each other through telephone, fax or direct computer link to negotiate prices of goods they buy and sell. In our above example, rational and self-interested consumers and profit-maximizing firms contact each other through any media and buy and sell things on the negotiated price.

If point A(-8, 5) is reflected over the line y=2 and then translated according to the rule (x,y) -> (x-1, y-4), what quadrant will point A be in?
9514 1404 393
Answer:
3rd quadrant
Step-by-step explanation:
The second-quadrant point will lie in the 3rd quadrant after reflection over the line. Its coordinates there will be ...
A'(-8, 2·2 -5) = A'(-8, -1)
Then, translation down and to the left will move it further into the 3rd quadrant, to ...
A''(-8-1, -1-4) = A''(-9, -5) . . . . a 3rd-quadrant point

Answer: D
Step-by-step explanation: $12
Zelda would have to pay $64 more per month than Don as per the given data. The correct option is C.
Since Don's credit score is 777, his FICO score range is 720-850, and he will be charged an interest rate of 5.59%. Thus, his monthly payment will be $860.
For Zelda, since her credit score is 709, her FICO score range is 675-699, and she will be charged an interest rate of 6.25%. Using this interest rate and the mortgage amount of $150,000, her monthly payment would be $924.
Therefore, Zelda would have to pay $64 more per month than Don. The answer is option C.

You and your friend collect each rocks and fossils. your friend collects three times as many rocks and half as many fossils as you. you collect 20 objects. your friend collects 20 objects. how many rocks andhow many fossils do you each collect. PLEASE ANSWER FAST! I DONT WANNA FAIL!!
Answer:
you - 4 rocks and 16 fossilsfriend - 12 rocks and 8 fossilsStep-by-step explanation:
Let the rock be r and the fossil be f
Equations
You: r + f = 20Friend: 3r + 1/2f = 20Double the second equation and subtract the first one:
2(3r + 1/2f) - (r - f) = 2*20 - 206r - r = 205r = 20r = 4Then find f:
f = 20 - 4 = 16So you collect 4 rocks and 16 fossils
